RS PRO Dial Dry Back and Vertical Thermometer Temperature Gauge

The principle of how Temperature Gauge work is around the idea of using two different bimetallic strips (usually steel and copper or steel and brass). When the strip is getting hotter, the metal is bending, and when the strip is colder, it shows the opposite. Therefore, the movement of the pieces correlates to the temperature indicating on a scale. The credit of this discovery goes to English Gentleman John Harrison in the 18th century. Even though the possibilities and technologies are constantly evolving, his findings are still valid. The Gauge is a simple, inexpensive and durable device to display the temperature of the surrounding atmosphere or an object. Their popularity reaches many industries, such as heating and ventilation, refrigeration industry, process manufacturing or process pipelines. Depending on your requirements, you can choose the right types of Temperature Gauge available on the current market. Some of them include magnetic thermometers (use with radiators), probe thermometers (use for food and gases) or clip Thermometers ideal for measuring the temperature of heating and water pipes. We are proudly introducing our own branded RS PRO-Dial Dry Back, and Vertical Thermometer Temperature Gauge with dual scale is covering both hot and chilled water range temperature. This 100 mm diameter Thermometer with bi-metallic movement and acrylic window cover indicates the surface temperature for applications, such as heating and ventilation process along with refrigeration industries. The Gauge scale oscillates between 0°C up to + 120°C, where the case material is steel. The Gauge complies to DIN 16203 standard meaning verification of lateral stability was part of the introduction.

Frequently asked questions

What to look out for when reading Gauge Thermometer?

The dial Thermometer contains a wealth of information, such as:

1. The Pointer indicates the temperature currently prevailing.
2. On display, we have information about the units measuring (PSI, °F, °C).
3. The accuracy class is either 1 or 2, and they depend on the scale spectrum defined error limits.
4. Dial Thermometers differentiate between scale range and measuring range.
