  • Page 5 Thank you for purchasing the new Gas-Pro. At Crowcon we recognise the need for reliable and robust personal monitors which are sized to be worn and simple to use. Gas-Pro is a portable monitor capable of detecting up to 5 gases in a compact and wearable design featuring an optional internal pump. Focused on users and fleet managers alike, Gas-Pro offers application focused solutions giving greater operating time and reduced set up time.

  • Page 6: Safety Information

    ‘Contacts’ section of the manual (see page 58). • Ensure maintenance, service and calibration is carried out in accordance with the procedures in the manual and only by trained personnel. • Gas-Pro must not be charged or have communication to the device, at ambient temperatures outside of the temperature range 0°C to 40°C. • Only connect to Gas-Pro in a safe area for charging or communications. • Charging cable assemblies, whilst nominally providing a voltage of 6.5V, must not exceed a voltage of 9.1V as this may impair intrinsic safety and invalidate safety certification (Um=9.1V). • Communication cable assemblies, whilst nominally operating at a voltage of 3.0V TTL, must not exceed a voltage of 9.1V as this may impair intrinsic safety and invalidate safety certification (Um=9.1V).

If the operator button is not pressed the countdown will complete and this function will be skipped.
  • Page 15 I f the Gas-Pro is configured for Bump functionality, the Bump/Pump prompt will be displayed if a flow plate is attached and a gas bump test is due or the Gas-Pro is placed in a Q-Test module during normal use (see Bump/Pump functionality on page 35). Prior to fitting, the flow plate’s gasket should be checked for any damage. The pump test ensures accurate sealing as well as monitoring pump performance.

    Gas-Pro can either be worn or used with hoses and probes to sample from spaces prior to entry. The pump capacity in the Gas-Pro is 0.5l/m and will draw a sample of gas from 30m within 80 seconds. Please note the expected losses for some gases below.

    Flow Plate Gas-Pro can also be tested simply by using the flow plate and applying gas If Gas-Pro is operated in pumped mode in combination with an exhaust pipe, a set of bellows should be used inline (e.g. flow plate, 2cm maximum tube, bellows, 3000cm maximum tube). EN60079-29 part 1 has been harmonised under the ATEX directive (2014/34/EU). Therefore to comply with the ATEX directive, portable apparatus sensing flammable gases should have a functional check with gas before each day of use. Other testing regimes may be employed depending on local circumstances.
