Crowcon Detective+ Transportable Multigas Area Monitor

120,060,000

Description

Crowcon Detective+ designed for group protection, area monitoring and providing a virtual fenceline, it is a rugged, interconnectable, multigas temporary area monitor. Building on Crowcon’s experience in pioneering this category of detector, Unit has earned a reputation for reliability and versatility in demanding environments stretching from offshore platforms to the sands of the Middle East.

Crowcon Detective+ Overview

  • Rugged and robust, the features either fixed or folding legs and a protective frame that allows stacking for easier storage.
    • 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 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.
    • 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.
  • 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.

Versatile and user friendly

  • Infrared sensors available – allows sampling of highly flammable gas levels and carbon dioxide. They are also unaffected by poisoning
  • Built-in pump option – provides fast response and extra sensor protection, and sampling versatility
  • Clear display – provides clear information and allows indentification of gas hazard

Rugged, tripod design

  • Raised sensor apertures – prevents water ingress
  • Folding or fixed leg options – allows stacking for easier storage and transportation
  • IP65 specifications – provides excellent sensor protection

Loud and clear alarms

  • 25 Detective+ units may be linked together, up to 100m from adjacent units – all linked Detective+ units indicate an alarm sensed by any one unit
  • Units sending an alarm flash faster – provides effective warning of gas hazards
  • Audible and visual confidence blip
  • Vivid red LED clusters for visual alarm
  • Multiple beacons – ensures 3600 visibility

Gases and Ranges

Required ranges and alarms may vary by country and application and these can be configured as required.

Gas Range Typical Alarms
Flammable gas  0-100 LEL 20% LEL
Oxygen (O2)  0-25%  19% & 23%
Hydrogen sulphide (H2S)  0-50 ppm 10 ppm
Carbon monoxide (CO)  0-500 ppm 35 ppm
Sulphur dioxide (SO2)  0-10 ppm  2 ppm
Chlorine (Cl2)  0-5 ppm  0.5 ppm
Nitrogen dioxide (NO2)  0-10 ppm  2 ppm
Phosphine (PH3) 0-5 ppm  0.5 ppm
Ammonia (HN3)  0-50 ppm  25 ppm
 Ammonia (NH3)  0-1000 ppm n/a
Hydrogen (non-flammable levels)  0-2000 ppm n/a
Hydrogen cyanide (HCN)  0-25ppm  10ppm

+ Reactive gas, care required during sampling, contact Crowcon for details.

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.

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
