GM70 Handheld Carbon DioxideMeter - 1

GM70 Handheld Carbon Dioxide Meter for Spot-Checking Applications Features • Two optional sampling methods: diffusion or pump aspiration • User-friendly meter with multilingual user interface • Numerical and graphical display of measurements • Data can be logged and transferred to PC via MI70 Link software The Vaisala CARBOCAP® Handheld Carbon Dioxide Meter GM70 is the demanding professional’s choice for hand-held carbon dioxide measurement. The meter consists of the indicator (center) and probe, used either with the handle (left) or pump (right). 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. 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. Vaisala CARBOCAPâ Technology GM70 incorporates the advanced CARBOCAP sensor that has unique reference measurement capabilities. The measurement accuracy is not affected by dust, water vapor or most chemicals. The meter has a two-year recommended calibration interval. Two Sampling Methods The handle is for hand-held diffusion sampling. GM70 pump enables pumpaspirated sampling from locations difficult to access otherwise. It is also ideal for comparisons with fixed CO2 transmitters. Interchangeable Probes GM70 uses the same probes as Vaisala CARBOCAP Carbon Dioxide Transmitter Series GMT220. 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 for Vaisala’s fixed CO2 instruments. GMW90 and GMP220 probes can also be adjusted by using the GM70 meter. GM70 has two probe inputs. Vaisala’s relative humidity and dewpoint probes can also be used simultaneously with CO2 measurement. MI70 Link The optional MI70 Link Windowsâ software and the USB connection cable form a practical tool for transferring logged data and real time measurement data from GM70 to a PC. Benefits • Proven Vaisala CARBOCAPâ reliability • Wide selection of measurement ranges • Easy recalibration using the interchangeable probes • Suitable for field checking of fixed CO2 instruments • Short warm-up tim
