I. Specification Crowcon infrared gas detector IRmax

Generality:

The reliability of the Compact IRmax Crowcon type stationary gas detector has been proven in hot, cold, wet and salty environments, making it ideal for offshore.
IRmax's unique optical components are treated with a high-strength coating that completely prevents errors due to condensation. Since IRmax contains no components for artificially heated optical surfaces, power consumption is significantly reduced, requiring only 1W of power..

Simple to install:

Compact size - requires little space, effort and time to install
Various mounting options - Crowcon IRmax infrared gas detectors can be wall mounted, fitted into a 50mm (2 inch) hose or connected to an auxiliary junction box using mounting accessories
Industry standard 4-20mA output - compatible with almost any control system
Optional for HART and RS-485 Modbus communication.

Easy maintenance:

Remote non-intrusive calibration - remote display can be mounted up to 30 meters from Compact IRmax Crowcon IRmax style fixed gas detector and test gas can be applied without direct access to the detector.
Handheld Intrinsically Safe (IS) Calibrator - The Crowcon IRmax infrared gas detector with IS fence module attached can be checked and calibrated using the IS handheld monitor.
STAY-CLIR optics - prevents condensation on optical components.

Low cost:

Low power - consumes only 1W of power, allowing the use of a small power supply and battery backup system.
Automatic optical occlusion monitoring - minimal routine maintenance keeps costs down.
