| Open-Path Analyzers |
Open-path analyzers are used to detect concentrations of hundreds of individual chemicals in real-time. Our open-path monitors utilize an expansive library of detectable gases for continuous monitoring of hazardous health sites to refinery emissions. Cerex open-path analyzers feature software programmable adjustment of alarm levels and user configurable relay activated alerts for gas faults. Alarm outputs include 4-20mA signals and SPDT relays for warning, alarms, and faults. Combined with a wireless or wired network our analyzers can relay concentration levels from remote locations to a central control station for immediate response.
For emergency response teams requiring the same performance of an open-path monitor without the setup time, our Hound-FR, UV Hound, UV Mini-Hound, and Canary offer part per billion (ppb) detection levels in an easy to use, ultra portable package. |
Open-path UV Sentry
The UV Sentry is a low cost open-path UV analyzer capable of accurate part per trillion (ppt) to percent detection levels. The UV Sentry can detect gases which may lead to human health hazards, often with lower detection limits than an IR based system. The UV Sentry is capable of detecting multiple compounds including chlorine, ammonia, and mercury.

Open-path Sentry-MS
The Sentry-MS is a mono-static open-path UV analyzer capable of accurate part per trillion (ppt) to percent detection levels. The Sentry-MS achieves lower detection limits than the UV Sentry over the same path length due to its double pass design. The Sentry-MS is capable of detecting the same extensive list of compounds with better detection limits by a factor of two.
