Hand-held carbon dioxide (CO2) analyzer with internal pump
To prevent condensation from occurring when drawing a gas sample from an environment with high humidity and temperatures into ambient air, an option called Nafionä tubing is available. The tubing prevents condensation in the gas sample by selectively removing the water vapor without affecting the level of CO2.
The GM70 incorporates the Vaisala CARBOCAP® Sensor, which is a silicon-based NDIR sensor that provides excellent reliability and long-term stability. Features include ten measurement ranges between 0...20% CO2 and a two year recommended calibration interval.
The GM70 has a multilingual user interface and a graphical LCD display. Data can be logged up to 30 days. The optional Windows® software provides an easy-to-use interface to a PC. Probes for measuring relative humidity, temperature and dewpoint temperature can also be connected to the GM70. A carrying case incorporates all the equipment and keeps the setup ready for immediate measurement.
