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.
The GMM220 series modules incorporate the industrial Vaisala CARBOCAP Sensor. The patented 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.
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 field service easy. In addition, the measurement range can be changed simply by replacing one probe with another.
The user has a choice of measurement ranges up to 20 % CO2 the Vaisala CARBOCAP Carbon Dioxide Module GMM221 for higher and the Vaisala CARBOCAP Carbon Dioxide Module GMM222 for lower concentrations of CO2. Different power supply voltages, output options, as well as cable lengths, connectors, and mounting gear are also available.

GMM111 Carbon Dioxide Module
· Compact CO2 module with flow-through aspiration
· Ideal for control of CO2 concentrations in incubators
· Incorporates Vaisala CARBOCAP, the silicon based NDIR sensor with unique internal referencing
· Advanced single-beam, dual wavelength measurement with no moving parts
· Measurement range options 0 .... 5 %, 0 .... 10 % and 0 .... 20 % CO2
· Excellent long-term stability
The Vaisala CARBOCAP Carbon Dioxide Module GMM111 is designed especially for control of biological processes where high CO2 concentrations are used. It has 3 optional measurement ranges 0 ... 5/10/20 % CO2. The GMM111 is a flow-through model and has barbed connectors for attaching the in and out flow tubes. As the module is not mounted in the chamber, the chamber can be heat sterilized without removing the module.
The Vaisala CARBOCAP CO2 sensors have been proven to be accurate and durable. They have an excellent long-term stability, which decreases maintenance. The superior performance of Vaisala CARBOCAP sensors results largely from the stable reference provided by the electrically tunable Fabry-Perot Interferometer(FPI).
The tunable FPI filter measures CO2 absorption, and simultaneously a reference wavelength. This internal reference measurement compensates effectively for any changes in the optical path, such as light source intensity changes and contamination.
In the HVAC market, this type of reference measurement is a unique feature to Vaisala CARBOCAP products.
The true internal reference measurement of Vaisala CARBOCAP CO2 transmitters provides years of stable CO2 measurements.
