I. Specification Detective+ portable multi-gas monitoring station
Generality:
- Rugged and robust, the Detective+ Crowcon area gas monitor features fixed or folding legs and a protective frame that allows stacking for easier storage.
- Available with an optional internal pump for flexible sampling, alarms are announced with a loud sound, while multiple beacons ensure 360-degree visibility.
- Existing Detective+ Crowcon Mobile multi-gas monitoring station can also be equipped with infrared (IR) sensors, providing CO2 detection or allowing for higher flammable gas monitoring. Infrared sensors also provide immunity to the toxic effects that standard flammable gas sensors can suffer. This extends sensor life and adds measurement reliability in tough applications such as water treatment plants and some chemical or hydrocarbon processing facilities..
Versatile and user-friendly:
- Infrared sensor available - allows Detective+ Crowcon Mobile multi-gas monitoring station to sample flammable gas and carbon dioxide levels. Unaffected by poisoning and has a very fast response time.
- Integrated pump option - provides sampling flexibility
- Integrated display - provides clear information and allows gas hazard identification.
Rugged design and tripod:
- Increased sensor aperture - prevents water from entering
- Optional folding legs - allows stacking for easier storage and transport
- IP65 specifications - for use in challenging environments
- Tripod Design - Increases physical visibility of the unit and is the perfect height to allow 360 air intake.
Loud and clear alarm:
- 25 NET detective or 12 Detective+ units with cables can be networked together forming an effective perimeter defense - Units on the network can be spaced up to 100m apart and if one alarms, all unit on network alarm.
- Smart and flexible devices send flash alarms faster - ensuring that the device is working properly and that they are protected.
- Sound and visual confidence score
- Vivid red LED cluster for visual alarm
- Multiple beacons - ensures 360 0 visibility
- Detective+ is now wireless.
- Detective Wireless is a wireless module that gives you a range of up to 100 meters excluding the use of cables.
- The Wireless Detective portable multi-gas monitoring modules can also be used as repeaters giving you a stronger signal in built-up areas and where signal strength is problematic.

Infrared Sensors |
||
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. | ||
