The Drager Polytron 5700 is a fixed flammable gas detector equipped with an Infrared poison immune sensor PIR 7000.  Class I, Division 1 certified, suitable for use in hazardous areas.

Common target gas measuring ranges: Methane 0 to 100 vol%  Or Propane, Ethylene, Methane with alternative ranges (see below).  The PIR 7000 sensor has an integrated library of 100 gases that can be picked from the menu, cross-calibration with a standard gas like Methane or Propane occurs, the procedure does not require returning the instrument or need specialist expertise. The sensor is also immune to dirt particles contaminating the optical housing; an integral four beam system counteracts the interference. A splash guard option adds further protection.  Sensors are drift-free and fit for the toughest of applications, for example, offshore deployment.

The output from the transmitter is 4-20mA 3 wire, available with relays which ensures communication with all control panels.

Housing options Epoxy coated copper-free aluminium, or stainless steel SS316 L. Docking stations can be included for increased safety (E), also assists commissioning. D versions without a Docking station.

Operating temperature -40 to 70°C (-40 to 158°F)

A remote sensor option is available, use of a calibration flow cell is required to facilitate calibration at the transmitter end.

Featuring the same advantages as other detectors in the 5000 range, a common interface, ability to act as a standalone detector, simplified menus, backlit display and selection of mounting options.

The Polytron 5700 has two PIR 7000 sensor choices, the 340 – has a bigger application scope with a different wavelength, offers alkanes detection at high sensitivity. Type 334 offers 0 to 20 %LEL and up to 100 %LEL, alternatively 0 to 100 %v/v for methane. For type 340, the full scale is configurable from 5 to 100 %LEL.
