The Detective+ transportable area monitor is based on the highly successful Triple Plus+ and Detective models, building on the reputation, reliability and versatility of its forebears. Detective+ is inherently rugged and robust, with a sturdy fixed or folding leg protective frame options. Loud and clear alarms can be transmitted between Detective+ units while an optional built in pump allows faster gas response and better sensor protection. Detective+ may now be equipped with infra-red sensor technology, which provides either CO2 detection, or allows higher flammable gas level monitoring and immunity to the poisoning effects which standard flammable gas sensors can suffer from. There are now two options for battery capacity, either 36 hours or 60 hours with standard configuration, providing remote sites with extended usage in-between charges. Couple these features with the wide range of toxic gas sensors available and it makes Detective+ one of the most versatile area monitors available. 55,000 Detective and TriplePlus+ users can't be wrong.
