Carbon MonoxideChlorineEthylene OxideFormaldehydeHydrogen ChlorideHydrogen PeroxideHydrogen SulfidePeracetic Acid [aka Peroxyacetic acid]Sulfur DioxideOSHA specifies an 8-hour TWA of 50 ppm. Setting the system alarm at 50 is not recommended, unless the workplace concentration is always teetering just below this level, and compliance with the 50 ppm standard is truly an issue.Although OSHA does not define a STEL or ceiling value for CO, NIOSH does, and it is 200 ppm. Absent the condition of meeting the 50 ppm standard, a more prudent course would be to set alarm-1 (the warning alarm level) at 100 ppm and alarm-2 (the danger alarm level) at 2...See more on gasdetection.com[PDF]STANDARD SPECIFICATION EM-02-04 gas sensor of the detector shall be of modular "plug-in" type without requiring any wiring work to facilitate easy replacement.

Working Principle LPG is an odourless gas which settles on the ground level. To detect any leakage, Ethyl Mercaptan is added to it. The LPG Leak Detector is a wall mounted device fitted close to the floor level with an alarm setting at 20% of Lower Explosive Limit.

- A gas detection system is used as a method of explosion protection - The hazard arises from the release or accumulation of explosive gases and vapours - The hazard arises from the release or accumulation of toxic gases

Improve safety and productivity with the most flexible, user-friendly tape-based gas detector for low-level toxics Features Benefits Visible at a distance with crisp, colorful LED bar on top of unit with flip screen

For continuous measurements without pumping the gas back it is recommended to collect the gas in an external gas collecting bag. Pumping the gas back into an external cylinder, vessel or gas compartment (up to 10 bar pe). The external bag can be emptied by using the MultiAnalyser SF6, a DILO service cart or compressor unit.

LEAKSPY SF6 For quick detection and quantification of small SF 6 leaks. 3-033-R200 LEAKSPY SF6 (Sensor length 300 mm). The cordless battery-operated LEAKSPY SF6 precisely measures SF 6 concentration in air by means of a non dispersive infrared sensor (NDIR sensor) and indicates the value on a graphic display in ppm v.The device allows precise localisation of leaks by searching the highest …

The RC400G residual chlorine analyzer employs a polarographic system that uses rotating platinum electrodes to provide continuous online measurement of residual chlorine concentration. By appropriate use of reagents, it is possible to separate residual chlorine (free chlorine + combined-chlorine) from free chlorine for measurement.

The BME680 is the first gas sensor that integrates high-linearity and high-accuracy gas, pressure, humidity and temperature sensors. It is especially developed for mobile applications and wearables where size and low power consumption are critical requirements.
