Cerex Hound Multi-gas Analyzer

The Cerex Hound series point gas detectors are portable multi-gas analyzers developed to detect part-per-billion (ppb) to percent level concentrations of multiple gases within a mixture. The Hound produces laboratory quality results in real-time using ultraviolet light absorption – similar to traditional infrared detectors, but features lower detection limits on many human health hazards and does not interfere with water vapor. All Hound series analyzers come standard in a weather-resistant case with an integrated display, active ambient air sampling, and wireless communication. The FR options are well suited for smoky or dusty environments with a faster sample rate and replaceable glass fiber sub-micron sample filter.
