• Vigor Technology SST900
• WiFi radio range up to 200m
• Both Wi-Fi +485/422
• Built-in lithium battery
• Measurement accuracy ±1″
• Resolution 0.05″
• Offset ≤±5″,
• Absolute linear error ≤±1.0″
SST900 levelmeter based on servo accelerometer principle, core sensitive devices resolution up to 0.1μg,
frequency response 10 Hz, SNR is more than 120 dB. The highest accuracy reach to ±1.0″.
Do not like as other levelmeter only to check null position which need very long warming time and large
cross-axis sensitivity, SST900 has rapid starting-time (less than 3 min), less than 0.1% FS cross-axis sensitivity
as well as less than 2 mrad misalignment. It can keep the same accuracy on any angle point.
SST900 is flexible to local and remote inspection with LCD indicator or Wi-Fi interface.
The featured iAngle mobile software can be runned on Apple® iPad/iPhone® devices
or other mobile terminal devices.
