This is how to use the JF-1A-ST "Stick" Handheld Conductivity Meter to measure Fuel Conductivity ASTM Test Method D2624 anywhere in the world. This video also shows how to use the JF-1A-ST-VC-SEF Box to verify and calibrate the Stick conductivity meter quite easily in the field. This means with these two paired you never have to return your equipment for calibration. The SEF Box is NIST Traceable and only requires calibration once every ten years. The Handheld can be calibrated once a year and verified whenever with the SEF box. This is the easiest and most cost effective way to measure fuel conductivity by hand. The JF-1A-ST Stick handheld is widely used by the US Military and the Commercial Aviation Industry to measure Jet Fuel Conductivity. With one SEF box you can maintain a fleet of JF-1A-ST stick handhelds, as the SEF box can calibrate any of them.
