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.
New! Detective+ is now wireless.
Detective Wireless is a wireless module that gives you up to 100 meters range excluding the use of cables.
The Detective Wireless 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 Wireless is backwards compatible enabling use with all version of Detective and Detective+, so it can be used on your existing fleet
