Senscient designs, manufactures and installs gas detection sensors for industrial applications. These sensors form a critical line of defense that industrial plant operators rely upon to safeguard against devastating consequences such as fires, explosions and the release of toxic gases. The Senscient ELDS laser-based open path gas detector from HMA Instrumentation is offered for a wide range of poisonous and flammable gases. The Senscient ELDS uses SimuGas self-testing to eliminate the need for employees to enter risky areas for gas checks. Nuisance false alarms are virtually removed with its innovative Harmonic Fingerprint processing.
