Expansion thermometers with scale for temperature reading
Glass Thermometers (resp. liquid-in-glass thermometers) are expansion thermometers. Usually they contain a liquid-filled jacket with a glass capillary and a scale for temperature reading. In proportion to the temperature change the volume of this liquid changes so that the capillary level increases or drops.
Within the scope of Glass Thermometers BITHERMA offers different kind of Industrial Thermometers in the field of industry. According to your industrial requirements you can expect the highest instrument quality.

Glass Thermometers / Machine Thermometers from BITHERMA
For precise temperature measurement in industrial environments, machine and glass thermometers are the traditional solution. Thermometers in this category operate on the principle of expansion and allow for accurate reading of the current temperature on an analog scale. With the wide variety of designs offered by BITHERMA, we provide suitable thermometers for your industry to ensure the safe and controlled operation of your machinery and systems.
How Do BITHERMA Glass Thermometers Work?
Glass thermometers are among the most important and familiar types of thermometers. They typically consist of a glass bulb filled with a colored liquid for better readability. A scale is positioned alongside the thermometer to correlate the movement of the rising or falling liquid in the bulb’s capillaries with a specific temperature. When the temperature of the measured medium changes, the volume of the liquid changes proportionally. This expansion or contraction is shown on the scale and indicates the current temperature in your machinery and equipment.
What Are Glass Thermometers Used For?
Glass and machine thermometers have been widely used for generations in monitoring and controlling the temperature of various machines and systems. Thanks to their simple installation and easy-to-read displays, they can be attached to many types of machinery. They are primarily suitable for basic temperature measurements in liquids and gases. The scale is typically graduated in one-, two-, or five-degree steps, depending on the temperature range. Therefore, they are not suitable for measurements in tenths or hundredths of a degree. In addition to industrial applications, this measurement technology is also used in conventional heating systems. The principle of displaying temperatures through liquid expansion is also used in portable glass thermometers, allowing for flexible measurement in a wide range of applications, not just fixed installations.
Diverse Product Lines for Every Application
The BITHERMA range includes a broad selection of thermometers that can be precisely tailored to your specific needs and existing machinery. Our models include, for example:
