Gas & Water Leak Detection: Crowcon Detection Instruments

July 2009 Vol. 64 No. 7

Crowcon’s flexible Tetra Personal Monitor alerts confined space workers to dangerous changes in air quality by detecting hazardous gases.

A top-mounted, backlit display provides gas readings, diagnostics and battery life; single button operation facilitates use with a gloved hand in small quarters. Fully interchangeable intelligent sensor modules allow customization to a specific air quality needs-oxygen, toxic and flammable gas detection.

For pre-entry confined space testing, an optional built-in electric sampling pump or a separate manual aspirator is available. The durable water and dust resistant unit gives instant warning of gas hazards with a powerful audible siren, an extremely bright LED and vibrating alarm. A Lithium-ion battery provides 18+ hours continuous operation from one charge. A 30-day countdown warns of calibration due date. 800.527.6926, www.crowcon.com
