Mobile CO2 measuring device

November 2019 Analytical Instrumentation & Environmental Monitoring

The measurement of CO2 emissions throughout industry is a critical activity. Across many industries, leaks in equipment resulting from non-maintenance, mechanical damage or wear and tear can impact on the wellbeing and safety of not only employees, but also on the manufacturing processes involved, for example, in the food, beverage and refrigeration industries.

Adding to its already extensive range of instrumentation, Greisinger, part of the GHM Group of Companies, has launched its brand new G 1910-2 and G 1910-20 CO2 mobile, handheld measuring devices. These offer benefits to the user such as a compact CO2 monitor with an integrated sensor and an optical and acoustic alarm function with a large rechargeable battery life, easy charging and a wide measuring range.

Jan Grobler, managing director of GHM Messtechnik South Africa, elaborates: “From breweries, wine presses and dispensaries to heating, ventilation and air-conditioning to energy management in buildings and use in research and education, this newly launched, compact handheld measuring device fits perfectly into the hand and can be taken anywhere.

“Every mining or pulp and paper plant, for example, has to monitor the environment and this device offers a wider measuring range than usual, which can reach up to 2000 ppm in the G 1910-02 version, and as much as 19 999 ppm with the G 1910-20 model. Additionally, having a calibration connection means the customer can recalibrate the device themselves, or we can do it for them. This eliminates the need to for devices to leave the place of operation for recalibration purposes.”

The devices are equipped with benefits such as a long-lasting rechargeable battery with low power consumption that enables measurements over a period of 24 hours. Standard AA NiMH batteries can be used and recharged via the Micro USB connection with a standard Micro USB charging cable without the need for a special mains adaptor.

The instruments also have alarms for applications in air quality monitoring, green houses and energy management. CO2 is measured with a high-class non-dispersive infrared (NDIR) sensor. The display of the time-weighted average over eight hours (TWA) or 15 minutes (STEL) can be read simultaneously.
