Flow-type air tightness leak detector AL-T90
The air tightness detector works on the principle of filling a sealed cavity with compressed air at a set pressure and detecting whether there is any leakage by measuring the changes in pressure or flow rate inside the workpiece. The instrument is equipped with a high-sensitivity and high-pressure-resistant pressure transmitter and a dedicated pneumatic valve with high sealing performance and reliable operation to form a basic air detection circuit. It features an extremely high test resolution, high detection sensitivity, powerful extended input and output control functions, data recording and statistical analysis functions, multi-channel parameter setting and selection, USB interface data output and other functions. With a full touch screen operation, it is simple and convenient to use, and can conveniently realize the automated testing of the air tightness testing process.
