一般描述
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:
Note: Do not use with combustible gases.
Specifications:
Sensitivity (minimum leak rate required to produce 10% deflection of full scale):
- Turn the unit on
- Zero out background air
- Probe for leaks
Note: Do not use with combustible gases.
Specifications:
- 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)
- Argon: 1.0 × 10-4 cc/sec (0.110 ft3/yr)
- CO2: 1.0 × 10-4 cc/sec (0.123 ft3/yr)
