Best Practices for Gas Monitoring in the Commercial Kitchen

ways; thus, the need for two CO sensors, or a redundant gas monitoring system. Installation Height: The two CO detectors should be mounted in the kitchen approximately 5 feet from the floor. This five foot height corresponds to the “breathing zone” of most people and is adopted as the de facto standard. CO is relatively the same weight as ambient air. The Dual Gas Monitoring System (CO/CH4 ...

Gas Leak Sensors | McMaster-Carr

An audible alarm and warning light alert you to the presence of propane, methane, hydrogen, and carbon monoxide. This detector has a relay for connection to auxiliary alarm systems. A programmable timer allows you to set whether the relay alarm is triggered immediately, or after 4 or 8 minutes of continuous gas exposure. The reset button suspends the alarm and restarts the cycle for 5 to 8 ...

Cable Type Sensor | Spot Type Sensor | Leak Detection

The zone type sensor or cable/linear detection sensor is designed to detect a leak in expansive and open areas. These water-sensitive cables can be put on the floor, wrapped around pipes, or attached to a wall for detecting leakage of clean or polluted water or other conductive liquid anywhere on the total length of the cable. It’s always difficult to predetermine the leak points in a large ...

Gas detector - Wikipedia

Gas leak detection is the process of identifying potentially hazardous gas leaks by sensors. Additionally a visual identification can be done using a thermal camera These sensors usually employ an audible alarm to alert people when a dangerous gas has been detected. Exposure to toxic gases can also occur in operations such as painting, fumigation, fuel filling, construction, excavation of ...

CO2 Gas Detection - Calibration Technologies

The recommended method for mounting CO2 sensors in a process leak detection system is to mount them in the breathing zone (~5 feet off of the floor). Mount the sensor wherever people frequent, do not mount close to a leak source unless people are always there. Do not mount the CO2 sensor lower than the breathing zone.
