Crowcon Flamgard Plus

Crowcon Detective+ Multi-Gas Temporary Area Monitor

The Crowcon Detective+ is a multi-gas temporary area monitor for use in turnaround/shutdown procedures, hot work maintenance, confined space entry work and many other utility, construction and oil and gas industry applications. Go solo or link together using Detective Net to form a perimeter, Detective+ gives a loud and clear alarm providing effective warning of gas hazards. The rugged, water and impact resistant design make Detective+ the ideal choice for your transportable gas detection needs.

Key Features:

  • Infrared sensors available – allows sampling of highly flammable gas levels and carbon dioxide. They are also unaffected by poisoning and have a very fast response time.
  • Built-in pump option – provides sampling versatility
  • Built-in display – provides clear information and allows identification of gas hazard

Rugged, tripod design

  • Raised sensor apertures – prevents water ingress
  • Folding leg option – allows stacking for easier storage and transportation
  • IP65 specifications – for use in challenging environments
  • Triple leg design – Increases unit physical visibility and is the perfect height to allow 360 gas inlet

Loud and clear alarms

  • 25 Detective NET units or 12 Detective+ with cables can be networked together forming effective perimeter defense – Units on the network can be placed up to 100m from each other and if one alarms, all units on the network alarm.
  • Intelligent and flexible units sending an alarm flash faster – provides guarantee to the use that the unit is functioning properly and they are protected
  • Audible and visual confidence blip
  • Vivid red LED clusters for visual alarm
  • Multiple beacons – ensures 3600 visibility

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. Find out more.

for details.


Infrared (IR) sensors for flammable gas can be supplied as a single range, 0-100% LEL, utlising a single display channel, or as a dual range, 0-100% LEL/0-100% volume, which then occupies two display channels.

Carbon dioxide sensors are supplied as 0-5% volume. Only one IR sensor can be fitted, and IR sensors can only be used in combination with oxygen and toxic sensors.

Gas Range Typical Alarms
Flammable gas  0-100 LEL 20% LEL
Flammable gas  0-100% v/v  None
Available for methane, propane, butane or ethylene
Carbon dioxide (CO2)  0 to 5% v/v 0.5 and 1.5% v/v
