Sulfur sticks are tools used in industrial ammonia refrigeration systems to detect minor ammonia leaks. A sulfur stick is made from a wick which contains particles of sulfur. The sulfur stick is lit and burns with an open flame, [1] and the color of the sulfur smoke is used to find the leak. When there is no ammonia present, the smoke is ...
The M8 detector paper does not detect agents in the form of aerosols or vapors. The M8 was a Canadian invention, being first standardized in 1963. [ 2 ] By 1964 it entered US service as part of the M15A2 Chemical Agent Detector Kit, with about 67,000 of these kits being produced from 1965-1969, with most other NATO nations also purchasing the M8.
Gas monitors and alarms for carbon monoxide and other harmful gases are increasingly available for office and domestic use, and are becoming legally required in some jurisdictions. Originally, detectors were produced to detect a single gas. Modern units may detect several toxic or combustible gases, or even a combination. [1]
The measured quantity is the sum of all the gas along the path of the beam, sometimes termed the path-integral concentration of the gas. Thus the measurement has a natural bias (desirable in many applications) towards the total size of an unintentional gas release, rather than the concentration of the gas that has reached any particular point.

A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas detector.It is non-dispersive in the fact that no dispersive element (e.g a prism or diffraction grating as is often present in other spectrometers) is used to separate out (like a monochromator) the broadband light into a narrow spectrum suitable for gas sensing.

Passing combustible gas raises the temperature further which increases the resistance of the platinum coil in the catalysed bead, leading to an imbalance of the bridge. This output change is linear, for most gases, up to and beyond 100% LEL , response time is a few seconds to detect alarm levels (around 20% LEL), [ 1 ] at least 12% oxygen by ...
