What's a Tridicator???

If you have ever seen a boiler, chances are you have seen a tridicator, but what does it do?

A tridicator is a combination of a bimetallic dial thermometer and a mechanical pressure gauge. These instruments are almost exclusively used in boiler systems. The tridicator allows for a visual temperature and pressure check to confirm that the system is working within the optimal pressure and temperature range. Many tridicators (like the one pictured above), also include a red-set pointer that allows the end user or OEM to set the pointer at the maximum temperature range as a quick indicator to the end user to confirm that everything is okay.

Merit Instruments & our manufacturing division has been manufacturing tridicators for decades. We offer a variety of dial sizes, shapes, temperature and pressure ranges, as well as all of the common stem lengths used in the boiler industry. With standard brass internals with steel cases, or our unique all stainless steel case and internal designs, we have a tridicator that will work with YOUR requirements! With our excellent engineering and product development teams, we can also custom manufacture a tridicator that fits YOUR specific requirements. We also offer versions with Polycarbonate or glass lenses.

If you need a tridicator, with or without your own custom logo and dial design, why not go straight to the manufacturer? Merit Instruments has a team of skilled sales people who will help you find the perfect tridicator for your requirements, and make doing business with us a pleasant experience!
