The measurement of CO2  emissions throughout industry is a critical activity. Across many industries CO2 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 their 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. They 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.


“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 CO2 handheld measuring device fits perfectly into the hand and can be taken anywhere. It is the most cost-effective portable device available” said Jan Grobler, Managing Director, of GHM Messtechnik South Africa.

“Every mining or pulp and paper plant, for example, has to monitor the environment and this device offers a wider measuring range than usual that can reach up to 2,000 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 enables 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” said Grobler.

The devices are equipped with benefits such as: a long-lasting rechargeable battery with very low power consumption which 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 device has an easy to read display, with backlighting.

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

Grobler added “CO2 is dangerous at a concentration of >3%, these new portable instruments of CO2 monitoring are ideal for warnings of moderate but non-dangerous levels. They offer an impressive price/performance ratio and a high durability as has come to be expected with German precision manufactured instrumentation”.
