PRODUCT DETAILS:

The OxyGuard CO2 Dissolved CO2 Analyser consists of a probe and a mains powered transmitter. The latter has a display, "slope" & "zero" adjustments as well as a 4-20 mA analogue output signal. The probe is delivered with a 7 m cable that can be shortened as desired.

The probe measures the carbon dioxide content of the water directly by detecting the carbon dioxide partial pressure in the water, it detects the free dissolved CO2.

The instrument's range is 0-50 mg/l. Before use the system is calibrated using mixtures of water and calibration chemicals in a special calibration beaker with stirrer.

Specifications:


Size:

    Probe: 40 mm dia. x 140 mm. Cable length 7 m.
    Meter: 120 x 120 x 58 mm
    Calibration Beaker: 65mm dia. x 260 mm

Weight:

    Probe with cable and transmitter 1.0 kg
    Calibration accessories 1.0 kg.

Supply:

    115 VAC

Range:

    0 - 50 mg/l dissolved carbon dioxide

Operating Conditions:

    3 - 35 degrees Celsius

Accuracy:

    Depends on calibration. Practicals accuracy up to +/- 1 mg/l

Response Time:

    Typically 5 minutes at 20 degrees Celsius depending on flow velocity past probe. In still water up to 15 minutes.

Flow Requirements:

    The instrument does not consume carbon dioxide for its measurement, but a certain flow is necessary to ensure that the sensing element of the probe is in equilibrium with the surrounding water and to avoid "spot" measurements.

Output:

    4 - 20 mA current loop
