Comet Co2g-xx External Probe Instruction Manual

CO2G-xx External Probe

Product Description

The External probe CO2G-xx is used for measuring the
concentration of CO2 in the air. The product is available in the
following model: Probe CO2G-10, with a range of (0 to 10,000)
ppm.

Technical Parameters

  • Temperature dependency: (0 to 10,000) ppm
  • Pressure dependency (1): t90 < 200 s
  • Response time: 15 s (the measuring interval depends on the
    settings of the instrument to which the probe is connected)
  • Operating relative humidity range: (0 to 95) % RH (without
    condensation)
  • Operating barometric pressure range: (700 to 1100) hPa
  • Probe connection: M12 circular connector

(1) … it is a residual dependency (the measured value is
automatically compensated to the current barometric pressure)

Dimensions

The CO2G-xx probe is manufactured by COMET SYSTEM, s.r.o.
Bezrucova 2901, 756 61 Roznov pod Radhostem, Czech Republic.

Installation

To install the probe, connect it to a newly purchased U2422
using an extension cable. Cables are available in 1 m (UWP001), 2 m
(UWP001-2), or 4 m (UWP001-4) lengths. The probe does not require
any special service or maintenance. It is recommended to
periodically verify the accuracy of measurement by calibration.

Important notice:

  • If you want to connect this probe to a U2422 datalogger which
    you have previously purchased with an older SN220 probe type, you
    may need to upgrade the device firmware and change probe settings.
    In this case, contact the service department.
  • If you want to connect this probe to any other Comet device,
    first check www.cometsystem.com to see if this probe is suitable
    for this device or what cables you will need. Older devices did not
    support this type of probe!

External probe CO2G-xx for measuring of CO2 concentration in the air
PRODUCT DESCRIPTION
CO2G-xx probe with the I2C output is designed to measure carbon dioxide concentration in the air in chemically non-aggressive environments. The CO2 measurement is based on the dual wavelength NDIR principle, which automatically compensates for ageing effects. The probe is IP65 rated and the replaceable filter offer protection in harsh environment. It is designed for connection to COMET devices equipped with input for external CO2 probes. The probe is interchangeable, the calibration constants are saved in the internal memory of the probe.
