VAISALA HM70 Series Portable Carbon Dioxide Meter

The Vaisala CARBCAP hand-held carbon dioxide meter GM70 is a user-friendly meter for demanding spot measurements in laboratories, greenhouses and mushroom farms. The meter can also be used in HVAC and industrial applications, and as a tool for checking fixed CO2 instruments.

The Vaisala 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 provides an easy way to handle data in a PC environment.

The Vaisala GM70 incorporates the advanced Vaisala CARBOCAP sensor that has unique reference measurement capabilities. The measurement accuracy is not affected by dust, water vapor or most chemicals.

The Vaisala GM70 features 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.

The Vaisala GM70 uses the same probes as the Vaisala GMT220 carbon dioxide transmitter series. By plugging different probes into the handle or pump, the user can easily change the measurement range of the GM70. The meter can also be used as a calibration check instrument. The GM70 has two probe inputs. Vaisala's relative humidity and dewpoint probes can also be used simultaneously with CO2 measurement.
