CO2 meter 535
Model 535, is a CO2 measuring instrument with permanently attached probe, and batteries.
An efficient CO2 measuring instrument for measuring indoor air quality. Bad air quality in rooms can lead to tiredness, lack of concentration and illness (Sick Building Syndrome) due to high CO2 concentration (greater than 1000 ppm)
* Long-term monitoring based on maximum and mean calculation
* Long-term stable 2 channel infrared sensor
* Highly accurate, highly efficient
* Repeated calibration is unnecessary

Portable Combustible Gases Detector
Gas detectors generally monitor gas concentrations based on the lower explosive limit. This is because even if a gas is present at concentrations exceeding the upper explosive limit, if a gas leakage occurs into the atmosphere, the gas will be immediately diluted and diffuse, bringing concentrations to within the explosive range. The unit %LEL is frequently used to express a concentration with respect to the lower explosive limit (100 %LEL).
