The TM3PD offers a compact size and highly versatile mounting possibilities. Designed without an integral HMI the size and cost are reduced dramatically. The TM3PD is capable of pressure tests up to 435 PSI. It is an ideal solution for automated leak testing environments where close proximity to the item under test and low internal volumes are desired. Leakage is measured using the pressure differential method where the pressure difference generated between the product under test and a reference volume is measured. The instrument is easy to install offering digital RS485/USB communication interfaces for PLC connections.
