The Tracker provides measurements for TGP (mmHg or % saturation), ΔP, barometric pressure (mmHg) and temperature (ºC).
Increasing water temperatures, injection of air in water, algal blooms or pressurized pumping can result in gas supersaturation. This may lead to bubble trauma or sub-lethal toxicological problems for aquatic species. The TGP probe provides a rapid and accurate measurement of total dissolved gas pressure.
The Tracker has simple calibration procedures and easy to understand menus. The handheld meter features a tough membrane keypad and graphical display with a user-selectable backlight. The Tracker has two pressure sensors, one measures total dissolved gas pressure (TGP), and one measures barometric pressure (BP). Also has datalogging capabilities. The batteries are rechargeable and an AC adapter is included with each unit.
