Pure Aquatics supplies a range of handheld and pen monitors for easy use in the field.
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.
| Specifications | Measured / Derived | Measurement Range | Resolution |
|---|---|---|---|
| Total Gas Pressure (mmHg TGP) | Measured | 0–1550 mmHg | 1 mmHg |
| Barometric Pressure (mmHg BP) | Measured | 0–1550 mmHg | 1 mmHg |
| Temperature (C) | Measured | 0.0–40 °C | 0.2 °C |
| Total Gas Pressure (TGP %) | Derived | 0 – 200% | 1% |
| ΔP [ mmHg TGP – BP) | Derived | 1550 – 1550 mmHg | 1 mmHg |
| 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 | 0.45 kg (1.0 lbs) |
| Handheld meter weight | 0.18 kg (0.4 lbs) |
