The professional measuring set is equipped with high-quality miniature quick couplings DN1.2, manufactured in Sweden, designed for precise measurement of static and dynamic pressure as well as vacuum in hydraulic systems. Built on a reliable “push-to-connect” mechanism with a secure ball, spring, and sleeve locking system, the couplings guarantee safe and leak-free operation. Both sockets and plugs feature integrated valves that ensure tightness even under vacuum conditions up to 90%. The hardened steel measuring plugs are exceptionally durable and maintenance-free, while threaded connections are sealed with O-rings for quick, simple, and reliable assembly. The set includes a measuring holder with a vent valve for eliminating air bubbles, significantly improving the accuracy of dynamic pressure readings. Flexible adapters and robust measuring hoses allow versatile use, including compatibility with TEMA SYSTEM 100 plugs commonly found in machines such as VOLVO, HIAB, and SAMSUNG, or with M16x2 threaded connections via the TA-M-139 adapter. Any standard manometer with a 1/4” BSP connection can be used, with the recommended FM-631 model ensuring optimal performance. Delivered in a durable plastic case, the set contains a low-pressure measuring holder, measuring plug with protective cap, high-pressure hose (DN2, 630 bar, L=2.5 m), and precision adapters with NBR sealing. With a working pressure of up to 600 bar (400 bar for TA-M-120 plugs), this set provides a reliable, flexible, and professional solution for hydraulic diagnostics in demanding industrial environments.
