Gas Leak Detector PCE-LDC 20
US$ 6,593.00
ex. VAT, ex. delivery costs
The gas leak detector for gas pressure systems is an effective solution for detecting and evaluating leaks in compressed air and other non-explosive gas pressure systems. The measured leaks can be recorded and analysed within the software, the escape of compressed air causes high electricity costs as compressors run more than they should.
