OxyGuard Polaris 2 TGP

Product catalog summary

Overview
The OxyGuard Handy Polaris TGP is a versatile hand-held gas pressure meter capable of operating in three distinct modes: as a standard Polaris dissolved oxygen meter, a Total Gas Pressure (TGP) meter displaying pressures as percent saturation, and a TGP meter showing pressures as volume percentages. It measures atmospheric pressure, total dissolved gas pressure, oxygen partial pressure, and temperature, and includes a data logger for ease of use.

Advantages
The TGP is user-friendly, featuring a measurement tube that can be easily replaced if fouled. Accurate measurements are achieved by calibrating the TGP against the barometric pressure sensor, allowing precise determination of the gas pressure difference between water and air.

Specifications

Dimensions: Meter: 98 mm diameter x 36 mm; Probe: 58 mm x 110 mm + cable gland.
Cable Length: Standard 3 m, customizable on request.
Operating Conditions: Probe: -5 to +45°C; Meter: -20 to +60°C.
Encapsulation: Short-term immersion proof up to 5m depth.
Display: Graphical LCD with variable backlight.
Measured Parameters: Oxygen partial pressure, atmospheric pressure, total dissolved gas pressure, temperature.
Oxygen Probe Type: Galvanic cell, self-polarizing, self-temperature compensating.
Self-check: Probe function, meter function, cable, battery.
Accessories: Storage pouch, DO probe membranes with O-rings & electrolyte, cathode cleaning pad.

Display Modes

Show TGP % Sat Mode: Displays pressures related to atmospheric pressure with 100% SAT (O2), 100% TGP (total), and 100% RES (rest; other gases).
Show TGP % Vol Mode: Displays 21% O2, 100% TGP (total), and 79% RES (rest; other gases).
Show Oxygen Mode: Displays DO in mg%l, DO in % saturation, and temperature.

Performance

Measuring Range: 0-60.0 ppm (mg/l) and 0-600% saturation.
Compensation: Automatically for temperature and barometric pressure; manual for salinity (0-59 ppt).
Accuracy: Typically better than +/- 1% of measured value +/- 1 digit.
Temperature Accuracy: +/- 0.2°C.
Repeatability: Typically better than +/- 0.5% of measured value.
Response Time (DO): 90% of end value in less than 20 seconds in water.

OxyGuard Polaris 2 TGP Hand held Total Gas Pressure Meter The OxyGuard Handy Polaris TGP is a hand-held gas pressure meter. It can operate in three modes, one where it acts as a standard Polaris dissolved oxygen meter, one where it is a Total Gas Pressure meter that shows pressures as “percent saturation” values of the actual atmospheric pressure and one where it is a Total Gas Pressure meter that shows pressures as volume percentages. To do this it measures the atmospheric pressure, the total dissolved gas pressure, the oxygen partial pressure and the temperature. The instrument incorporates a data logger.
