Carbon dioxide probes for air conditioning

July 2012 Maintenance, Test & Measurement, Calibration

The Jumo range of air conditioning products from ASSTech now includes probes to measure the concentration of carbon dioxide. The generators work according to an infrared principle featuring a patented autocalibration process, ensuring superior accuracy for many years.

Heating, air conditioning and ventilation systems can be controlled to meet various requirements and time constraints through process variables such as humidity and temperature, air quality, or other combinations. This helps reduce energy costs and is especially important for economical operation in large buildings such as hospitals, hotels or public facilities.

The new carbon dioxide measuring probes are available in indoor and duct versions so that rooms, halls and other indoor spaces can be ventilated for the exact time necessary. Precisely controlled air exchange ensures a healthy climate in a room and optimal physical comfort.

The patented autocalibration process is designed to compensate independently for any ageing effects, and guarantees outstanding long-term stability. Measuring ranges can extend through 0-2000, 0-500 or 0-10 000 ppm. Standardised analogue outputs with 0-10 V or 4-20 mA are available for the measuring signal.
