PT2X Pressure & Temperature Sensor
The PT2X Pressure & Temperature Sensor. Highly accurate water level sensor. So used for observing flow patterns, testing pumps and monitoring groundwater. Versatile, highly accurate sensor records water level and temperature. With integrated datalogger so collects up to 520,000 records. Easy to use software. Most importantly can be connected to other sensors. Thermally compensated for volatile conditions. Therefore ideal for wells, tanks, tidal studies and any application where ‘mm’ accuracy is important.
