Precision Levelling & Angular Measuring Instrument

Digi-Pas® is a registered trademark of JSB Tech and Digi-Pas USA LLC ( We are a global-leading manufacturer of digital inclinometers, electronic levelling instruments and tools providing a full range of precision digital level, tilt angle, surface flatness and alignment-diagnostic instruments innovated for professionals, specialists, tradesmen & DIY users. In 2009, Digi-Pas® pioneered the world's-first dual-axis precision digital level and in 2011, we further pioneered the world's-first 2-axis intelligent machinist level that have greatly simplified any high precision machine levelling and planar angle measurements tasks. In 2012, we sustained our innovation by presenting the world-first Digi-Pas® 2-axis ultra-precision inclinometer in Tokyo.

This business division specialises in the design and manufacture of HIGH QUALITY yet AFFORDABLE digital levelling instruments to replace the use of traditional Spirit Levels and those conventional single-axis pendulum-based electronic Inclinometers. Digi-Pas® products are built with advanced 2-axis MEMS Technology Sensor, and precisely compensated for nonlinearity and temperature variation to effectively withstand stringent operating environments. As precision leveling, angle measurement and alignment tasks essentially involve a plane or two dimensional surface (i.e. 2-axis), while traditionally leveling instruments are limited to single axis, Digi-Pas® has empowered many engineers by eradicating constraints associated with using single-axis instrument that requires them to conduct leveling tasks one axis at a time and tedious trial-and-error iterations. The 2-axis numeric digital simultaneous display and wireless measurement capabilities offer FAST, ACCURATE & PRECISE measurement of angles (0° ~ 360°) at resolutions of 0.1°, 0.05°, 0.01°, 0.001° & 0.0002° (5µm/M or 1 acrsec.) unmatched by any traditional spirit levels or conventional single-axis pendulum-based electronic levels/inclinometers.

The unique products of Digi-Pas® are Design Registered, Patented, and certified by TÜV SÜD, SGS to comply with CE, FCC, C-Tick, RoHS, IP65 and product accuracy performance to specification are verified by accredited 3rd party independent Calibration & Test laboratories in USA, Japan, UK and Germany providing Calibration Certificates conforming to NIST, JIS, UKAS & DIN.
