The Gas Detector AQ-500 is a highly accurate instrument for measuring ozone concentrations in the air. The Gas Detector can be equipped with four different heads that vary in their measurement range. Furthermore, the Gas Detector has sensor heads for other gases available, which are automatically recognized when plugged into the device. Thus, you can use the Gas Detector in many different areas. The possibilities of the Gas Detector extend the use of ozone in your processes for bleaching oils, greases, wax, paper, synthetic fibers, cellulose or textiles,within the paper, textile, or lubricant production industries. Another field of application for the Gas Detector is in cleaning, disinfection and sterilisation of swimming pools, water treatment facilities or after fire damage or water damage. With a head for lower measurements of up to 0.150 ppm, you can measure ozone concentrations that have a negative effect on the mental state of humans.
