Handheld TGP Tracker

The new InWater Tracker provides measurements for total dissolved gas pressure (TGP), ΔP, barometric pressure and temperature.  

Built on Point4 technology for reliable, rapid and accurate measurements, but with an improved display, easier data handling and more durable components.

Probe dimensions

Length: 19 cm (7.4 in)
Diameter: 4.2 cm (1.6 in)

Handheld meter dimensions

Length: 16 cm (5.1 in)
Width: 8.4 cm (3.3 in)
Height: 2.8 cm (1.1 in)

Probe weight

Handheld meter weight

0.18 kg (0.4 lbs)

Temperature range

Storage / Operating: -5 °C to +60 °C

Response time

Typical: 5 minutes (90%)
***Response time is improved by insuring there is water flow past the probe. However, this is a passive measurement and therefore can require up to 1 hour for accurate measurements.
