GM70 Hand-held HVAC Meter set with carrying case, CO2 and RH probes

The Vaisala CARBOCAP® Hand-Held Carbon Dioxide Meter GM70 is a user-friendly meter for demanding spot measurements in HVAC and industrial applications, and as a tool for checking fixed CO2 and RH instruments. In this set you get both a CO2 probe and a RH probe.

In the CO2 probe the accuracy has been optimized for low CO2 concentrations, up to 2000 ppm. For the best accuracy, it is advisable to always use the lowest sufficient measurement range for the application.

The GM70 also supports the use of Vaisala's humidity, dew point and moisture in oil probes, making it a sound investment applicable to several multi-parameter applications. Two probes can simultaneously be connected to the GM70.

The MI70 Link Windows® software and the USB connection cable form a practical way for transferring logged and real time measurement data from the GM70 to a PC.
