About the Mini Gas Leak Detector

•t

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.

•t

Ranges: Low x 1, High x 100

•t

Adjustable sensitivity for low & high ranges

•t

Time constant/Average

•t

Operating Temperature: 20oC ± 11oC

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.

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.
