WebCatalytic gas detectors require a routine “check” every 90-days. While no routine calibration is actually required for IR detectors, a gas check is still recommended every 90-days. Typically, calibration takes between 1 – 3 minutes. Should a catalytic sensor require replacement, it can easily be changed out in the field. WebAn LEL Detector or LEL Meter detects dangerous levels of a combustible gas or solvent vapor in air, expressed in percent Lower Explosive Limit, or LEL. An LEL Detector is an integral part of a complete gas detection system and can be referred to as a Gas Detector or just a fixed gas detection system. Give Us a Call 409-908-4898
