2-Axis Precision Levelling Instrument
Models: DWL 1500XY, DWL 2000XY, DWL 3000XY & DWL 3500XY Series


I purchased the Digi-Pas® 2-Axis DWL3500XY (Bluetooth model) on the recommendation from Hurco. It was mainly for leveling the 5 axis equipment. What I found is I use it for every leveling process we perform regardless of the application. The Bluetooth feature is the best. You can set and calibrate the level in one single spot and it will give you X and Y real time feedback to your laptop. This is great on large machines. You can make a leveling screw adjustment while being on the floor behind the machine and if you have your computer or Android device you can see it as you make the adjustment. This level will cut a leveling process by 75% no joke! It is the best purchase I have ever made for our service department.

I inspect, calibrate, and certify these units on a regular basis. I have several customers that submit them for annual calibration and have yet to see one not meet specification. I see these in all conditions, from abused to pristine. My experience is one of durability and reliability. That being said, they are precision instruments and should be handled accordingly. Customer Service has been outstanding. They reply promptly and efficiently.

Digi-Pas® DWL3000XY (Bluetooth version) has enough capability in terms of usability, functionality and accuracy. It is very easy for our machinist to use when installing and setting up CNC machine centre in factories. The 2-Axis graphical LCD display is very clear, precise and high quality. The Bluetooth connectivity on PC Sync Professional software is very helpful for wireless remote measuring and data logging which cuts down machine set-up time, manpower and increase productivity.

We are extremely pleased with Digi-Pas® 2-Axis DWL3500XY digital machinist levels after working with our customers on this product for over a year. These instruments have been very well received and with overwhelming feedback from all our users that they have found these levels to be a greatly superior alternative to traditional single-axis machinist levels, with many benefits, including speeding up alignment procedures and reducing training level for new operators to reliably achieve precise levelling results. The 'live' Dual axis readout is simply brilliant, especially for operators experienced in having to meticulously taking readings in both directions over and again with traditional single-axis levels. In my opinion, the ability to directly read off precise, live, digital level readings in both directions (2-Axis) simultaneously represents a major step forward in the industry. This greatly simplifies and speeds up the process of levelling precision machine, even more than I anticipated when I first saw this impressive technology presented by JSB TECH - to an extent that may only be truly appreciated by people who have used other levelling methods.

Digi-Pas® DWL3500XY is working out very well for us as we have been using it successfully for various testing and alignment of our instruments. The dual-axis static levelling accuracy, precision and repeatability are performances that we were looking for in our laser beam vector alignment (or misalignment measurement) to our Lidar (Light Detection and Ranging) sensor mechanical reference frame (in an absence of our precise inertial measurement unit) is well provided by DWL3500XY. The USB connectivity with PC Sync software is also much valuable to us.

Digi-Pas® DWL3500XY dual-axis precision angle measurement unit is easy to use, sturdy and could be mounted to a surface. We used for characterizing a high precision rotator for one of our machines. The rotator is used to orient a measurement module at many different angles. The DWL3500XY can be placed on the instrument, set the angles of interest and take direct measurement with a known angular accuracy. The DWL3500XY makes this process much more efficient than other methods available whereby there are some errors associated with those alternative methods that are difficult to quantify.

The Digi-Pas® DWL2000XY dual-axis precision Digital Level was a straight forward alternative for the traditional single-axis spirit level. This piece of instrument has superb accuracy combined with the temperature stabilization feature is awesome for the kind of research we do in Cavendish Laboratories, University of Cambridge. The level meter has been instrumental in the alignment of the experimental surfaces which have to be totally flat to ground. This feature was lacking in the earlier single-axis spirit levels which we used to use. With the DWL 2000XY, the alignment job has boiled down to few minutes compare to hours which we used to spend earlier. The 2-axis simultaneous digital readouts display gives it the strength in dealing with planar (two-dimensional) leveling and alignment in a non-trivial way when working in glove boxes compared to the traditional spirit levels.

Digi-Pas® DWL3000XY is helpful tools for us to measuring a heel angle of a moving boat that is laying in the water. We like the feature of data logging from computer using USB, as this feature help us to save data into excel spreadsheet for further data analysis.

Digi-Pas® DWL3000XY High Precision Digital level which I purchased never fail me during my applications. It's 2-Axis mode provides an accurate mean to ensure our Satellite dish alignments and Antenna installation processes are within controlled specification.

I really appreciate your team in assisting me to use the Digi-Pas® 2-axis DWL5000XY precision inclination sensor module in my research. The sensor is working very well and I'm currently running various tests to gain access on angular measurements. I think the control box is great. I just plug it in and it works without any problem. Using the RS232 converter for direct access to the single sensor module angular data takes a little more work, but once I got the wiring right it worked wonderfully. Thank you again.

I use the spirit level Digi-Pas® DWL 80E to control the measurement of bridge bearings (inspection of pot slide bearings). It is very suitable as a measuring tool on the often inaccessible and small measuring planes to determine the position in the plane; very helpful is the magnetic adhesion at the sliding surfaces, the accuracy in the parts per thousand range is sufficient.

We use Digi-Pas DWL 80 Pro for measuring our track on Formula racing car. For this we place the instrument directly on the hub of the wheel. For a better measurement result, we do six measurements per wheel and average this value; the level is placed in a vertical position to the road. After the first measurement, we change the angle perpendicular to the road by about 5 degrees each direction. Then we turn the inclinometer by 180deg. and repeat the procedure just described. The measurement results differ by only 0.15 deg.. Unfortunately, the magnet does not help us because of the aluminum hub. Compared to conventional methods of measurement with analog level we can quickly and accurately measure the fall. In addition, this device saves a lot of weight and space. We also use the inclinometer for aligning our wheel load scales to each other to bring all four of them to the same height. We are very satisfied with this device. Possibly an illuminated display would be helpful.

We use Digi-Pas® DWL180S Digital Inclinometer Module for guiding robotic arm grip and placement of work-piece precisely when feeding work-pieces into CNC machines. Its flat mounting surface contact is perfectly designed for fitting directly onto the gripper arm of our 6-axis robot arm handling system. This enables us to obtain precise gripping angle easily for achieving accurate gripping position when picking up and placing work-pieces. As a result, Digi-Pas® DWL180S module effectively improved the set-up time and reduced the error rate of our robot arm handling system.

Digi-Pas® DWL200 is a well-made, easy to use digital level. I'm very happy with the quality, features and price. I chose it over the 'cube' type ones as I wanted a fairly long (in length) level that would give me a better seating on a flat surface. The magnet works great and very secure.

I purchased Digi-Pas® DWL280 to get accurate readings on tilted solar modules. I was able to get the job done right in twenty minutes with this tool. Good display, easy to use. I prefer metal then plastic housing so I take "one star" off for that. That does not detract from its excellent performance. I will keep this in my tool bag for future reference.

By using Digi-Pas® DWL-80Pro Digital Level for levelling my panoramic tripod head in 3 directions, very accurate overlaps multi exposure of 12 pictures in 2 rows can be obtained so perfect (free of parallax) that I actually only make minor color adjustments but all other details were stitched without adjustments in Photoshop. In the picture taken, I didn't do it just to show how good levelling results with much less post-processing. Small dimensions and good accuracy in combination with easy-to-use, Digi-Pas® is a nice small tool that fits in my camera bag.

Digi-Pas® DWL80E has made the setup of my telescope so much easier. This is a very handy product. I am a beginner astronomer, and I bought this device to help set up my telescope. The magnetic grip was helpful in holding the level in place so I could level my scope. Once I was satisfied with the levelling, the angle gauge work like a charm in getting me to the right altitude.

Digi-Pas® DWL-200 Torpedo Digital Level is a great tool. I used to have a long 600mm Digital Level in the past. Digi-Pas® is very convenient - small in size, light weight, with magnet, precise, with buzzer sound. I realize that it is not necessary to have a long level all the time to get the angle or slope on-site. I carry the Digi-Pas® with me (in notebook bag) all the time.

I'm a professional roof contractor. I have difficulty bringing the long Spirit Level to the roof and usually spent large amount of my time reading the bubble at the vials and often, I need to be very close to my level to see bubble at vial. Now with Digi-Pas® DWL-130 (Clip-On), the digital readings have speed-up my work and I can read the digital measurement from a distance. Digi-Pas® is really handy as I can add it to various length level when is needed. I Love this novel invention.
