General description

This highly sensitive leak detector is excellent at finding leaks quickly, without the risk of contaminating the instrument associated with liquid leak detectors. Lightweight and compact, it includes a hand-held sniffer wand that allows the location of leaks to be pinpointed. This unit operates on the same principle as a thermal conductivity detector, it responds to any gas that has a thermal conductivity value different from that of air. It is easy to use, and can be operated with little or no training:
  • Turn the unit on
  • Zero out background air
  • Probe for leaks
This unit can be powered through an electrical cord, or by charging an on-board battery. The power cord, battery, and charger are all included.

Note: Do not use with combustible gases.

  • Detector: thermal conductivity cell with thermistors
  • Pump: diaphragm type
  • Visual Readout: LED bar graph
  • Zero: automatic with drift elimination
  • Audio Signal: audible alarm with adjustable setpoint and volume
  • Battery: rechargeable Ni-Cd
  • Battery Life: 8 hours, can be recharged to 95% of capacity in 1 hour
  • Dimensions: 3 1/4 in. (8 cm) wide × 1 13/16 in. (4.5 cm) high × 5 1/4 in. (13 cm) deep

Sensitivity (minimum leak rate required to produce 10% deflection of full scale):
  • Helium: 1.0 × 10-5 cc/sec (0.012 ft3/yr)
