TPI 725L Tightness Test Kit

The TPI 725L Tightness Test Kit combines two essential tools for gas and HVAC professionals in a single, value-packed kit. The TPI 608 Digital Manometer accurately measures pressure from -150mBar to +150mBar, providing four selectable units of measurement. Meanwhile, the TPI 725L Gas Leak Detector offers 40ppm methane sensitivity with an easy-to-use flexible gooseneck sensor for pinpointing leaks.

Reliable Performance for Gas Engineers

Designed for tightness and let-by testing, the TPI 608 Manometer ensures precise pressure readings with temperature compensation for reliability. It features a backlit display, wall hook, and magnets for hands-free operation, making it easy to use in confined spaces. The TPI 725L Gas Leak Detector quickly identifies leaks with both visual and audible alerts, allowing for fast troubleshooting.

The kit includes a durable A900 protective carry case, ensuring both instruments remain secure and portable. With an intuitive design, one-touch zeroing, and selectable measurement units, this kit provides a simple yet effective solution for professionals conducting gas system safety tests.

Whether you are performing routine inspections or troubleshooting gas leaks, the TPI 725L Tightness Test Kit delivers the accuracy and reliability needed for essential fieldwork. Its combination of precision pressure measurement and gas leak detection makes it an excellent investment for HVAC and gas engineers.
