General Monitors IR400 Point IR Gas Detector
The IR400 Infrared (IR) Point Detector is a hydrocarbon gas detector that continuously monitors combustible gases and vapours within the lower explosive limit (LEL) and provides alarm indication.
It features an industry-leading response time of less than 3 seconds, even with a splash guard installed. All electronics are contained within an explosion-proof housing so that the IR400’s detector information can be processed locally. Configurations with analogue output, Modbus and HART are also available.
Features
- Multiple communication outputs provide complete status and control capability in the control room.
- Dirty optics indication discriminates between true fault and cleaning requirements.
- Fast calibration times reduce the amount of calibration gas required, which lowers maintenance time & costs.
- Industry-leading speed & response: T90 ≤ 3 seconds, even with a splash guard installed.
