GasCheck G3 advanced gas leak detector

The Edwards GasCheck G3 features a Micro Thermal Conductivity sensor for enhanced sensitivity. At the heart of the instrument is a sensor which can detect any gas with a different thermal conductivity to that of air. Leaks can be located and the gas leak rate can be displayed in a choice of convenient units.

Where several measurements are to be taken, the G3 can log 10 readings with a date and time stamp.

The battery powered instrument is supplied in a rugged carrying case with a short probe, nozzle and a long probe.
