Description
The Testo 312-4 electronic differential pressure measuring instrument is specifically engineered for professional load and tightness testing on water and gas distribution pipelines. Operating with an internal sensor measuring up to 200 hPa, it simplifies system verifications through preset measuring processes. The device supports automatic recording of measuring values over several hours with an internal memory capacity of 25,000 readings. It features high durability for everyday industrial tasks, can interface with an infrared fast printer, and supports external high-pressure probes up to 25 bar for scalable diagnostics.
Industrial Applications
- Performing legally compliant tightness and load tests on industrial gas pipes using preset menus
- Conducting pressure tests on drinking water and waste water pipe installations with air or water
- Checking static gas, gas flow, and burner nozzle pressure settings on industrial boilers
