Portable CO 2

monitoring device

The measurement of carbon dioxide (CO 2 ) emissions is a critical activity throughout industry. Across many industries, CO 2 leaks in equipment, resulting from inadequate maintenance, mechanical damage or wear and tear, can impact on the wellbeing and safety of employees and on the related manufacturing processes – in the food, beverage and refrigeration industries for example. Adding to its already extensive range of instrumentation, Greisinger, part of theGHM group of companies, has launched the new G 1910-02 and G 1910-20 mobile, handheld CO 2 measuring devices. The compact CO 2 monitors incorporate integrated sensors and optical and acoustic alarm functions. They also have long-lasting rechargeable batteries and offer easy battery 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, the newly launched CO 2 measuring device fits perfectly into the hand and can be taken anywhere. It is a conveniently portable and

cost-effective device,” says Jan Grobler, Managing Director of GHM Messtechnik South Africa. “Every mining or pulp and paper plant, for example, needs to monitor the operating environment and this device offers a wider measuring range than usual, reaching up to 2 000 ppm in the G 1910-02 version and as much as 19 999 ppmwith the G 1910-20model. Additionally, having a calibration connection enables the customer to 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,” Grobler adds. Benefits include the long-lasting rechargeable battery with low power consumption,whichenablesmeasurements over a period of 24 hours. StandardAANiMH 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 monitoring instruments also incorporate alarms useful for various

applications: in air quality monitoring, green houses, and for energy management. The CO 2 is measured with a high-quality non-dispersive infrared (NDIR) sensor via an opening at the instrument’s head. The display of the time-weighted average (TWA) over eight hours or 15 minutes can be read simultaneously. Grobler adds, “CO 2 is dangerous at a concentration of more than 3%. These new portable CO 2 monitoring instruments are ideal for warnings of moderate but non-dangerous levels. They offer an impressive price/performance ratio and high durability, as is expected with German precision manufactured instrumentation.”
