Gas Leak Detectors

Product catalog summary
Overview: AGC Instruments' Mini Gas Leak Detector (Model 21-072) is designed to detect gas leaks from pressurized systems using a thermal conductivity detector. It is highly sensitive, capable of detecting helium leaks as small as 1 x 10-5 cc/sec, and other gases like refrigerants and argon at slightly higher rates.
Principle of Operation: The device operates by passing a probe over the area to be checked. The probe draws in a sample automatically, and the thermal conductivity detector registers a signal if a leak is detected. This method avoids contamination associated with traditional soap solutions and allows access to difficult locations.
Specifications:
  • Detector: Thermal Conductivity with thermistors
  • Visual Readout: LED Bar Graph with adjustable brightness
  • Peak hold with settable duration
  • Pump: Diaphragm type with speed control
  • Voltage: 115/230V, 50/60Hz
  • Battery: Rechargeable Ni-Cd, 7.36V/800mAh, with 7-8 hours life
  • Ranges: Low x 1, High x 100 with adjustable sensitivity
  • Operating Temperature: 20°C ± 11°C
  • Dimensions: 20.95 x 4.60 x 13.34 cm
  • Weight: Instrument 476g, Charger 277g
Performance: Minimum leak rates for 10% deflection of full scale include:
  • Helium: 1.0 x 10-5 cc/sec
  • Argon: 1.0 x 10-4 cc/sec
  • CO2: 1.1 x 10-4 cc/sec
  • Refrigerant: 1.1 x 10-4 cc/sec
  • 40% H2/60% He: 1.0 x 10-5 cc/sec
Caution: The Model 21-072 is not suitable for detecting leaks of combustible gases.
Contact Information: Headquarters in Shannon, Ireland, and a sales office in Beijing, China. Contact details are provided for both locations.

Gas Leak Detectors-1

Gas Leak Detectors Specifications: • Detector Thermal Conductivity with thermistors Visual Readout: LED Bar Graph with adjustable brightness Peak hold with settable duration Pump: Diaphragm type with Pump speed control Battery: Rechargeable Ni-Cd, 7.36V/800mAh Battery Life: 7-8 hours, recharged to 95% of capacity in 1 hour About the Mini Gas Leak Detector Low Battery Indicator, Very low battery shutdown AGC Instruments offers the Mini Gas Leak Detector (Model 21-072) which will easily find any gas that is leaking from a pressurised system. By using a thermal conductivity detector, this instrument will respond with speed to any gas mixture that has a thermal conductivity different to air. Adjustable sensitivity for low & high ranges Time constant/Average With a high signal to noise ratio, via amplification we are able to deliver a maximum usable sensitivity. Helium leaks of 1 x 10-5 cc/sec are easily detected. Other gases include Refrigerant leaks of 1.1 x 10-4 cc/sec and Argon leaks of 1.0 x 10-4 cc/sec. Zero Manual with drift elimination Weight: Instrument: 476g / Charger: 277g Principle of Operation The probe is passed over the area to be checked, a sample is drawn in automatically into the thermal conductivity detector. A signal is registered on the meter when a leak is detected. Minimum leak rate required to produce 10% deflection of full scale: This clean and easy to use system ensures that no contamination is left that traditionally is caused when using a soap solution. By using the probe, it is easy to reach difficult locations within a system. The probe is small enough to find the exact location of a leak. The model 21-072 is not designed to be used to determine leaks of combustible gases. www.agc-instruments.com Headquarters Shannon Free Zone West, Shannon, Co.
