Tridicators

4 products

Tridicators are a combination between a bimetal thermometer and a pressure gauge, measuring both temperature and pressure at the same time. They used to measure altitude as a third measurement (hence the "tri" prefix), but this has fallen out of use. These instruments are designed specifically for hot water boilers.
