Dwyer Instruments dial thermometers are designed to read the temperature at the point of measurement and also at a remote location with the help of capillary tubing. These DBT Series bi-metal thermometers are ideal for use with HVAC ducts, boilers and chiller temperature monitors. They feature a solar-powered design, a digital display with 0.1 degree resolution and a glow-in-the-dark dial for carrying out measurements in dim- or poor-lit conditions. Choose from a wide range of these dial thermometers available in stem lengths ranging from 2.5 to 24 inches on Raptor Supplies, an authorised distributor of Dwyer Instruments.
