Vaisala GMP80P & Indigo80 | CO2 Probe, Pump Sampling & Handheld Indicator

The Vaisala GMP80P portable carbon dioxide probe comes with pump sampling, along with the Vaisala Indigo80 handheld measurement indicator. With a CO2 measurement range of 0 to 20%, the GMP80P has a built-in pump, actively drawing air samples into the sensor, allowing for efficient and rapid measurement of CO2 levels.

The Indigo80, part of the Indigo family of transmitters and probes, is a handheld data logger that provides measurements for various parameters including humidity, temperature, dew point, H₂O₂ vapor, and moisture in oil.

Check out the Vaisala HMP110 Humidity and Temperature Probe as an optional add-on.
Customers can find the Vaisala GM70 Hand-Held Carbon Dioxide Meter as a substitute model for similar applications.
