InWater Tracker Overview 

The InWater Tracker is a handheld meter with a 2.4” display, push

-button interface, and re-chargeable 

battery.  It can log probe data to internal memory, which can be transferred to a computer via USB.  

When connected to an InWater TGP probe, the meter will display real-time total dissolved gas pressure 
(TGP) in mmHg and % saturation, barometric pressure (BP) in mmHg, temperature in Celsius (degC) and 

ΔP (TGP

-BP).
