The company’s industrial 5 and 9” thermometers as well as HVAC bimetal, solar digital and hot water thermometers are supplied with a removable thermowell. Thermowells create sealed systems where temperature measurement can be safely performed. With the media contained, thermometer replacement or service can occur without draining or shutting down the system. Thermowells protect thermometers as they isolate them from media that may be harmful or corrosive. They also shield the sensing element from high pressures.
