Model PG - handheld single or multiple gas detector

The instrument is intended to be used for the protection of personnel entering or working within an environment where a gas hazard may or is known to exist. PG is an intrinsically safe portable multi-gas instrument for use in category EEx iad potentially explosive atmospheres.It can be fitted with up to 4 sensors in various combinations of flammable, oxygen and toxic gases to provide simultaneous monitoring of each gas.

Using the PC Interface facilities, automatic data logging allows exposure levels to be stored for downloading to a personal computer and data retrieval following any incidents.



  • wide range of gas detection capabilities up to four sensors per analyzer
  • flammable gas selection from built -in menu
  • programmable alarm levels for each sensor
  • internal data-logging facility standard
  • data Logging in 3 modes • certified intrinsically safe
  • display backlighting
  • built-in audible & visible alarms
  • rechargeable or dry battery packs available
  • internal intrisically safe pump (optional)
  • belt clip & hook
  • PC interface - facilitates downloading, viewing or printing
  • (data logged), instrument configuration, calibration   (report printing) & programming
