For harsh environments

The Vaisala CARBOCAP® Carbon Dioxide Module Series GMM220 are designed for Original Equipment Manufacturers (OEM’s) requiring carbon dioxide measurements in harsh and demanding applications.

Vaisala CARBOCAP®

The GMM220 series modules incorporate the industrial Vaisala CARBOCAP sensor has unique reference measurement capabilities. Its critical parts are made of silicon; this gives the sensor outstanding stability over both time and temperature.

Since water vapor, dust, and most chemicals do not affect the measurement, the GMM220 series modules can be used in harsh and humid environments.

Sensor. The patented

Interchangeable probes

The GMP220 probes are interchangeable. They can be removed, reattached or replaced at any time – without the need for calibration and adjustment. The interchangeable probes make calibration and eld service easy. In addition, the measurement range can be changed simply by replacing one probe with another.

Dierent conﬁgurations

The user has a choice of measurement ranges up to 20 % CO the Vaisala CARBOCAP Dioxide Module GMM221 for higher and the Vaisala CARBOCAP Dioxide Module GMM222 for lower concentrations of CO

Different power supply voltages, output options, as well as cable lengths, connectors, and mounting gear are also available.
