Acugauge® TK-9A-PLUS Backflow Test Kit 3-Valve

Acugauge® TK-9A PLUS Backflow Preventer Test Kit 3-Needle Valve



The Acugauge® TK-9A PLUS is a 3-valve backflow preventer test kit used by certified backflow testers for testing backflow preventer assemblies. With the Acugauge® TK-9A PLUS backflow preventer test kit, you can test all makes, models and sizes backflow assemblies, including irrigation, domestic, isolation, containment and fire. The Acugauge® TK-9A PLUS backflow preventer test kit ships fully assembled and with everything needed to start testing right away: hoses, adapters and carrying case. The  Acugauge® TK-9A PLUS backflow test kit also comes with a printed calibration certificate, dated day of shipment and valid for one year.


An upgrade to TK-9A

Built entirely with stainless steel instrument-grade needle valves (high, low and bypass), the Acugauge® TK-9A PLUS Backflow Preventer Test Kit has risen the bar for 3-valve test kits. The virtue of the needle valve is a small orrifice with a long, tapered seat and a needle-shaped plunger, creating a vernier efffect, especially useful where accurate control of flow is required. In testing backflow preventer assemblies, we work with 1/10th of a degree PSID, for example, the difference between 5.1 and 5.2. The ergonomic design of the stem and plunger of the needle valves on the Acugauge ®TK-9A PLUS backflow test kit assures not only great ease of use and reliable operation, but also guarantees no slippage or integral leakage, so common with conventional test kits. These benefits amount to more precise readings and longer gauge life. The exceptional features of needle valves give them a clear upper hand over conventional ball valves as used on the TK-9A and other 3-valve test kits. In fact, needle valves are so crucial to backflow testing technology, that every backflow test kit must consist of at least one needle valve, at a minimum. The Acugauge® TK-9A PLUS and TK-9A are built on the same manifold and platform, and utilize the same differential pressure gauge and testing procedures, only the valves are different: TK-9A uses 2 ball valves and 1 needle valve, whereas the TK-9A PLUS uses 3 instrument-grade stainless steel needle valves.
