Vaisala CARBOCAP® technology
The GM70 incorporates the advanded Vaisala CARBOCAP® Sensor. The patented sensor has unique reference measurement capabilities. Its critical parts are made of silicon; this gives the sensor outstanding stability over both time and temperature. In addition, the measurement accuracy of the sensor is not affected by dust, water vapour or most chemicals.

The GM70 has a two-year recommended calibration interval.

Two sampling methods
The handle is for hand-held diffusion sampling. The GM70 pump enables pump-aspirated sampling from locations difficult to access otherwise. It is also ideal for comparisons with fixed CO2 transmitters. Due to its short warm-up time, the GM70 is ready for use almost immediately. The menu-based interface is easy to use, and a graphical LCD display with data logger function makes the handling of measurement data convenient.

The optional MI70 Link Windows® software in combination with a USB connection cable provides an easy way to handle data in a PC environment.

Interchangeable probes
The GM70 uses the same probes as Vaisala CARBOCAP® Carbon Dioxide Transmitter Series GMT220 fixed CO2 instruments. By plugging different probes into the handle or pump, the user can easily change the measurement range.

Two inputs provide flexibility
The GM70 has two probe inputs. This allows differences to be measured, and is also a practical feature when checking probes against a calibrated probe. Vaisala’s relative humidity and dewpoint probes can also be used simultaneously. The meter can also be used as a calibration check instrument for Vaisala’s GM20 and GM220 series fixed CO2 instruments. GMP220 probes can even be adjusted by using the GM70 meter.
