Product overview
Introduction to GM70
Vaisala CARBOCAP® Handheld Carbon Dioxide Meter GM70 measures volume concentration of CO
2
gas and displays
the result in the units of ppm or %. The exceptional stability and reliability performance of GM70 comes from the
advanced silicon based Vaisala CARBOCAP® sensor.
Basic features of GM70
Numerical and graphical multilingual displays
Data logging possibility
A tool for checking the reading of fixed CO
2
transmitters
A tool for adjusting Vaisala GMP220 series probes
Possibility for an analog output (voltage signal 0 … 1 V)
Sampling methods: diffusion sampling (GMH70 handle) or pump-aspirated sampling (GM70PUMP), alternatively
Multiprobe operation; any combination of 2 Vaisala DM70, GM70, HM70, and MM70 series probes can be used,
for example, for simultaneous CO
2
and dew point measurements
The optional, ready-to-use MI70 Link Microsoft Windows® software, which allows an easy way to handle
measurement data using a USB instrument cable or an RS-232 serial communication cable.
Using GM70 with Vaisala carbon dioxide probes and transmitters is discussed in the respective User Guides, available at
