1219 – Used Dräger Polytron IR Ex gas detector

300.00 ex.

This used Dräger Polytron IR Ex is a gas detector for continuous monitoring of flammable gases and vapors in ambient air. It offers all benefits of fail-safe IR measurement technology for applications in rough industrial environments. The transmitter converts the gas concentration signal into a 4 to 20 mA analog output. It is designed for one-man calibration and offers a variety of diagnostics and selftest features. The configuration and calibration of the transmitter is menu guided and easy to perform, using the built-in keypad. With the ATEX-approval (device category II 2G acc. to 94/9/EC) and the IECapproval for world-wide applications the Dräger Polytron IR Ex is suitable for use in potentially explosive atmospheres zone 1 and zone 2.

The transmitter Dräger Polytron IR Ex is a measuring instrument with an optical system which, based on its 2-fold reflected IR-beam and its optimized IR measuring wave length, is very sensitively reacting on hydrocarbon concentrations. Hence for e.g. propane, butane, gasoline vapors, ethers, alcohols, or amines etc. measuring ranges down to 1000 ppm or 5 % LEL full scale value can be adjusted. Also, measuring ranges up to 100 % by vol. for methane are possible

FEATURES AND BENEFITS

  •  Intrinsically safe protection design:
  • easy to install – easy to maintain
  • Unambiguous linear output signal
  • Configurable measuring ranges in the lower ppm-range or % LEL-range
  • Configurable measuring range up to 100 % by vol. Methane
  • Standard version with LC display and keypad
  • Calibrated to methane
