While many of the older, standard gas detector units were originally fabricated to detect one gas, modern multifunctional or multi-gas devices are capable of detecting several gases at once. Some detectors may be utilized as individual units to monitor small workspace areas, or units can be combined or linked together to create a protection system.

Apr 23, 2020The POLI multi-gas detectors (MP400/MP400P/MP400S) offer 4- or 5-gas monitoring of oxygen (O 2), combustibles (LEL), toxic gases, carbon dioxide (CO 2), and volatile organic compounds (VOCs).The MP400 and MP400P are basic models with O 2, LEL, carbon monoxide (CO) and hydrogen sulfide (H 2 S) configuration in both diffusion or pumped versions, for confined space entry compliance.

When the ozone gas exists, the sensor's conductivity gets lower along with the gas concentration rising. Users can convert the change of conductivity to correspond output signal of gas concentration through a simple circuit. MQ131 ozone gas sensor has high sensitivity to ozone, and also has sensitivity to strong oxide such as Cl2, NO2 &etc.
