Features
Applications
Features
- CO2 measurement range 0-20 %
- Vaisala CARBOCAP® CO2 sensor with excellent long-term stability
- Measurement compensated for effects of temperature, pressure, and background gas. The temperature compensation can be based on an integrated temperature sensor or use a set temperature. Pressure and background gas parameters can be set to the probe.
- Heating to avoid condensation on optical elements
- Digital output with RS-485:
- Modbus RTU
- Vaisala Industrial Protocol
- Analog output:
- Current output (0 – 20 mA or 4 – 20 mA)
- Voltage output (0 – 5 V or 0 – 10 V)
- Can be used as a standalone probe or with Vaisala Indigo transmitters
- Compatible with Indigo80 handheld indicator and MI70 handheld indicator
- Can be connected to Vaisala Insight PC software for configuration, diagnostics, and temporary online monitoring
- Easy plug-in, plug-out.
Applications
GMP251 is ideal for life science incubators, cold storages, fruit and vegetable transportation, and for all demanding applications where stable and accurate %-level CO2 measurements are needed.
A flow-through adapter with gas ports is available as an accessory, enabling tubing for easy and flexible remote measurement with a separate pump. A multiplexer can also be added for sampling gas from several locations.
