Crowcon Detective Plus IR Sensor Modules - Dual Range 0-100% LEL & 0-100% - Ethylene, Propane, Methane or Butane Models
The Crowcon Detective+ is a rugged, water and impact-resistant multi-gas monitor for temporary areas. Ideal 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 or cables 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. Methane, Propane, Butane, or Ethylene options.
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.
