GM70 Hand-held Carbon Dioxide Meter for Spot-Checking Applications

The Vaisala CARBOCAP® Hand-held Carbon Dioxide Meter GM70 measures volume concentration of CO2 in the units of ppm or %. It is a user-friendly meter for demanding spot measurements in laboratories, greenhouses, mushroom farms, and for ensuring CO2 safety during soft drink bottling processes. The measurement accuracy is not affected by dust, water vapor or most chemicals. The meter can also be used in HVAC and industrial applications, and as a tool for checking Vaisala's fixed CO2 instruments. Also the GMW90 can also be adjusted by using the GM70 meter.

The optional GM70 pump enables pump-aspirated sampling from difficult to access areas, such as incubators and chambers. Two sampling methods are available: the handle is for handheld diffusion sampling and the GM70 pump enables pump-aspirated sampling from locations difficult to access otherwise.

The handheld meter has two probe inputs; Vaisala’s relative humidity and dew point probes can also be used simultaneously with the CO2 measurement. The GM70 has a short warm-up time and is ready for use almost immediately. It has a menu-based interface, a graphical LCD display and data logging capability.

The optional MI70 Link Windows® software in combination with a USB connection cable is used to transfer logged data and real time measurement data from the GM70 to a PC.
