The Level TROLL 700H, available in a vented (35ft (11m)) configuration, exceeds USGS surface water stage-accuracy specifications. 3D factory calibration ensures accuracy across all field temperatures. And low-maintenance deployment saves on time in the field and cost. This premium instrument easily integrates with accessories and in-well mounted telemetry systems. Add HydroVu Data Services for real time feedback on all of your water monitoring sites.
As the most accurate water level data logger on the market, the Level TROLL 700H exceeds the USGS surface water specification of ±0.01 foot, achieving accuracy of ±0.01 foot up to 15 feet and ±0.1% of reading >15 feet.
3D Factory Calibration
Piezoresistive titanium pressure sensors are calibrated across full pressure and full temperature for accuracy across all field temperatures and certified for NIST® traceable factory calibration.
Certified Calibrations
In-Situ performs an independent check on every sensor to confirm that it was manufactured and calibrated correctly.
Vented System
Venting the cable and instrument removes the atmospheric pressure and provides the greatest system accuracy.
VuSitu
