PRODUCT DATA SHEET GASCHECK G4 GAS LEAK DETECTOR The GasCheck G4 features an improved Micro Thermal Conductivity sensor for enhanced sensitivity and piezo disc pump for increased reliability. 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. Datalogging is now possible over a long period of time (up to 10 days continuous) meaning less back and forth to download data. With the G4, you get a lightweight carry case which holds all the key accessories (delivered as standard) and it also protects the unit during transit. direct display of gas leak rate Large LCD colour display 10 days of data logging
