Key Features and Benefits:
Versatile Measuring Ranges : The Dräger Polytron 2IR offers flexible configuration options. It's capable of measuring methane levels in anaerobic digesters and landfill gas environments. The device can be set for various ranges, including 0 to 100% Lower Explosive Limit (LEL) for typical applications, and lower ranges (0 to 20% LEL, 0 to 5% LEL, and even ppm) for leakage or workplace limit monitoring. Additionally, it can measure methane up to 100 volume %.
Advanced Optical Technology : Equipped with double-compensating, non-imaging optics and a 4-beam process, this device ensures accurate readings. It also features a large gas library, capable of detecting up to 38 substances (27 of which are performance approved in accordance with DIN EN 50054/50057).
Rapid Response and Convenient Outputs : Experience quick response times, enhanced by the "chimney effect" of the splash guard. The transmitter provides an analog signal (4 to 20 mA) and digital output signals including RS 485 and HART®, with a multidrop feature.
Maintenance and Safety Features : This model includes a beam block warning for dirty optics, configurable maintenance signals, and is certified SIL-2 compatible for safety integrity. It also features a hermetically sealed stainless steel housing (SS 316L) and boasts a typical lifetime of 15 years.
Durable and Reliable : Designed for tough environments, it operates in temperatures from -40 °C to +65 °C and is suitable for moist atmospheres. The device has no movable parts, minimizing maintenance needs.
Global Compliance and Protection Standards : The Polytron 2IR meets international explosion protection standards (ATEX, IECEx, UL, CSA) and offers dust ex-protection for zones 21 and 22. It is rated IP 65, IP 66, and IP 67 for robust protection.
