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 CO2 detection, 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 cant be wrong.

Up to 4 gases monitored in a rugged and sturdy protective frame Ultra-loud 104 dBA sounder and red LED cluster alarms Wide range of sensor options including infra-red Long 36 or 60 hour battery life Raised detectors, coupled with IP65 specification provides excellent sensor protection Built-in pump option to provide faster gas response 12 Detective+ units may be linked together, up to 100m from adjacent units

Superb pedigree Detective+ is based on the highly successful Triple Plus+ multi-gas monitor which has sold over 55,000 units worldwide
Versatile and user friendly Infra-red sensors available allows sampling of potentially high flammable gas levels and CO2 infra-red sensors are unaffected by poisoning Built-in pump option provides fast response and extra sensor protection Display provides clear information, allows identification of gas hazard Easy tracking of multiple hazards Up to 60 hour battery operation Wide range of toxic gas sensors available
Extremely loud and clear alarms Wailing omni-directional siren, 104 dBA @1 metre High intensity red LED clusters provide visual alarm indication All linked Detective+ units indicate an alarm sensed by any one unit Units actually sensing alarm have faster LED flash Audible and visible confidence blip Time weighted average alarms for 8 hours and 15 minutes averages
Uniquely rugged, tripod construction Detectors are fully protected, even if device is overturned Raised detectors prevent water ingress Easy and quick to set up Folding or fixed leg options provide easy storage and transportation
