Hound Series Portable UVDOAS Point Gas Analyzers

The 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 versions are well suited for smoky or dusty environments with a faster sample rate and replaceable glass fiber sub-micron sample filter.


Three primary versions are offered, differing in size, weight, sensitivity (depending on sample path length) and communication features.


The Micro Hound-FR is the smallest and most portable Hound model. The Mini Hound-FR is a mid-size model that balances low detection limits with excellent portability. The Hound-FR is the largest and most sensitive model, equipped with wheels for rolling transport.
