Leak testing equipment is used to measure the escape of liquids, vacuum or gases from sealed components or systems.

Gas sensors interact with a gas to initiate the measurement of its concentration.

Residual gas analyzers (Rags) identify the gases present in vacuum environments.

Liquid level sensors are used to detect liquid levels or interfaces between liquids such as oil and water or liquids and solids.

Smoke detectors are designed to sense the products of combustion.

Heat detectors are fire detection devices that sense heat produced by combustion.

Liquid leak detectors sense when a liquid is leaking from a pipe, tank, or other receptacle area
