DSU-01-XX-R Detective + Transportable 4-Gas Area Monitor, CH4 % LEL, O2, H2S, CO (H2 Filtered) Non-pumped, Standard Battery with Rigid Legs by Crowcon
Detective+ is now wireless. Detective Net is a wireless module that gives you up to 100 meters range excluding the use of cables. The Detective Net modules can also be used as a repeater giving you a stronger signal in those areas that are built up and that have issues with signal strength. Detective Net is backwards compatible enabling use with all version of Detective and Detective+, so it can be used on your existing fleet.
Designed for group protection, area monitoring and providing a virtual fenceline, Detective+ is a rugged, interconnectable, multigas temporary area monitor.
Building on Crowcon's experience in pioneering this category of detector, Detective+ has earned a reputation for reliability and versatility in demanding environments stretching from offshore platforms to the sands of the Middle East.
Rugged and robust, Detective+ features either fixed or folding legs and a protective frame that allows stacking for easier storage.
Available with an optional internal pump for sampling versatility, alarms are announced with an extremely loud sounder, while multiple beacons ensure 360 degree visibility.
Detective+ may now also be equipped with infra-red (IR) sensors, providing either CO2 detection, or allowing higher levels of flammable gas monitoring. IR sensors also provide immunity to the poisoning effects which standard flammable gas sensors can suffer from. This extends sensor life and further increases measurement confidence in tough applications such as water treatment plants and certain chemical or hydrocarbon processing facilities.
