IR PLUS
IR Plus is a dependable, durable, and exceptionally sturdy dual-beam infrared hydrocarbon gas detector. With optional display capabilities, this device ensures swift and fail-safe detection of methane, propane, and various other hydrocarbon further enhances its reliability, making it an ideal choice for demanding environments.
Where to BuyIR Plus is a dual-beam infrared (IR) hydrocarbon detector, designed to ensure safety in the heavy industrial sector by providing real-time, fail-safe detection of methane, propane, and more. With over 50 years of expertise, Crowcon has engineered IR Plus to deliver unmatched stability, durability, and speed, even in the harshest environments. Its intelligent heater optics and STAY-CLIR hydrophobic reflectors resist dust, moisture, and corrosive chemicals, eliminating false alarms and downtime.
The IR Plus responds in just 4 seconds, giving you critical safety information fast, and its tested resilience ensures reliability under extreme conditions, including high temperatures and humidity. Offering a leading 5-year warranty for reduced maintenance costs, the IR Plus also supports flexible, non-intrusive testing with multiple display options and standard output choices like 4-20 mA analogue, RS-485 (Modbus), Local-HART, and HART over 4-20 mA, making it adaptable for various monitoring systems.
