202Eh leak detector (202-Ex, 202 Ex)
 
202Eh leak detector is used in hazardous areas, and outdoors in areas where there is produced, stored and used gas, such as chemical, petrochemical, metallurgical, pharmaceutical industry, LPG ​​(liquefied petroleum gas) station to detect and show the gas leak.
This device can be installed on two levels of alarm values. The detector can signal when the gas concentration reaches a given.
