About HVAC, Environmental & Industrial Thermometers

Industrial thermometers are notably more stable than regular thermometers. They are extremely accurate and have a considerable lifespan. This is because they don't have any mechanically moving parts, which means no material fatigue and no consumption of electrical energy.

An industrial thermometer is filled with liquid. The higher the measured temperature, the more this liquid inside expands. The expanding liquid climbs inside the tube and delivers the temperature to a display next to the tube.

Industrial thermometers come in different shapes and forms. One of the things in which they differ is the angle at which the immersion tube is attached to the thermometer itself. For different situations, different angles of attachment may be necessary.
