Extraordinary for its automation level, ST200PT is proposed on the market as most innovative instrument for test on gas pipelines. Few steps for the use, best technology in terms of electronic and excellent performances in terms of precision and repeatability, make ST200PT an instrument indispensable for everyday work. Thanks to its internal flash memory, it is possible to store both technician names that work with instrument and costumer database. In this way, it will be possible to associate the tests to the costumer and the technician that who makes the control for a perfect traceability for each performance. The instrument is supplied complete of a sturdy IP67 watertight suitcase, containing all connections suitable to the connection on pipes and into ST200PT/S model is included also IR infrared printer where it is possible print all test results. Data transmission is possible also via Bluetooth+Wi-Fi (optional) or with USB output type C. It is possible store tests on the microSD memory card (not supplied). Data logger function, touch colour graphic display and rechargeable lithium battery also externally, complete the panorama of the instrument.

ST200PT performs the gas plant leak test in a completely automatic way: just to turn it on, select the desired test and wait for the result.
