Description

The thermometer model IFC is an expansion thermometer for universal use in the areas of machine building, refrigeration industry, food and beverage industry as well as heating, air-conditioning and ventilation technology.

The temperature is measured by the extension of a thermometric liquid inside the capillary. Thermometers of this type are used for temperature measurement in locations that are difficult to access and for bridging long distances. The IFC is an inexpensive and a very reliable measuring instrument due to its very simple construction and using a

plastic case.

The IFC Expansion Thermometer combines reliability and affordability in a compact design that is both practical and durable. It features a non-electric, thermometric

liquid mechanism within a capillary, making it suitable for hazardous or remote locations where electronic devices may not be feasible. The capillary design enables accurate temperature readings over extended distances, making the IFC model ideal for use in difficult-to-access areas.

It is available in a range of temperature scales to suit diverse applications across multiple industries, from refrigeration and HVAC to food processing and manufacturing. The simple yet effective construction of the IFC Expansion Thermometer enables quick installation, with flexible mounting options for panel, wall, or direct line attachment, allowing seamless integration into existing systems.
