3D Factory Calibration
Pressure sensors are calibrated across full pressure and full temperature for accuracy across all field temperatures and certified for NIST® traceable factory calibration.
Titanium and sealed construction outperforms and outlasts specially coated data loggers. And a sealed battery reduces potential leak paths.
Use the powerful VuSitu mobile app to view results instantly from your smartphone or tablet when connected to the Wireless Rugged TROLL Com. Features include Log Setup Assistant, Universal Data File and Simple Data Management for improved efficiency and results.
Extended Shelf Life
The battery indicator on Rugged TROLL 100 and 200 instruments is controlled by an algorithm so that it will not count down until your unit is deployed and has taken at least 1,000 readings or is more than 9 months past its manufacturing date.
