Quest Engineering carries indicators. A 21st century term for instruments that measure temperature and pressure of a gas or liquid, indicators are more commonly known as gauges. Why not just say gauges?

Because we go out of our way to supply uncommon gauges and other indicators as well as the common ones. We're serious about solving any problem - common or uncommon - you might have with reading temperature and pressure in your fluid applications. (For example, we have little indicators with dial faces in sizes that range from one-and-a-half to eight-and-a-half-inch diameters.)

Problem reading pressure? We can solve it...from 30 inches of mercury to 15,000 psi.

Problem with vibration? A typical solution: Our glycerin-filled pressure indicators. Accuracy? From 1/4 of 1.0% to 3.0%. Stainless? Bronze? Digital? Quest can do it. Ammonia? No problem. Guarantees? You bet! From one to five years. Just ask us.

Problem with temperature indicators? We have them. Bimetal. Gas-actuated. Vapor-actuated. Mercury-in-glass. Temperature ranges from -100ƒ F to 1000ƒ F. A seven-year guarantee on bi-metal thermometers. Thermowells? Yes. Gauge protectors? Yes. Made of brass? stainless? Teflon®? Yes..yes. And yes.
