Inwater technology tpg tracker
The InWater TPG Tracker is a handheld, portable device providing reliable and accurate measurements of total dissolved gas pressure, ΔP, barometric pressure and temperature. The Tracker is the perfect tool for spot checks or to data log at adjustable intervals. The ergonomic design allows for single handed operation of the tracker while deploying the probe with the other hand.
