  0.0 to 7200 Arcsec Dual-Axis
Resolution of 1 Arcsec (≤ 5µm/M)
Accuracy ±1 Arcsec at 0 to 1080 arcsec
  ±3 Arcsec at other angles
3D surface geometry graph using PC-Sync Software for high accuracy surface flatness profile measurement
3-points contact base for most stable surface-to-surface contact to prevent “rocking”
Digital colour graphic display of Dual angles
4 X AAA 1.5V batteries
Enable USB External power source
VibroMeter Display real time vibration graph
AngularMeter Display real-time angle graph
Professional PC Sync Software USB connection to device for remote data logging
Wireless Bluetooth Class 1 connection (approx. 30 Meters) from PC to device

Instant 2-Axis simultaneous digital display of high resolution & accuracy providing a comprehensive solution for precision levelling, alignment, surface profiling & vibration measurements, completely eliminate trial-and-error (i.e. going back and forth) to take reading one axis at a time, resulting in time saving and quality professional works.
Digital colour graphic & numeric display to enable real-time collection & storage of digital angle/levelling/alignment/surface profile data for machine commissioning accountability & analysis.
The remote reading Wireless/USB Cable capability via PC/Tablet/Smartphone providing advantages that traditional single-axis spirit level or single-axis digital level is difficult or unable to match. i.e. effectively, only one person is required to level/align a machine.
Instrument accuracy is verified by accredited 3rd party Calibration & Test bodies and National Metrology Centre of Singapore traceable to SI standard and NIST, JIS, UKAS & DIN under CIPM MRA.
