SIKA precision bimetal dial thermometers are the proven solution for on-site temperature measurement of liquids and gases in industrial applications. They are suitable for installation in pipelines, containers, machines and plants and do not require external power supply. Due to the high protection class (IP65) and the insensitivity to ambient temperature fluctuations due to the measuring principle, we also recommend these versions for outdoor use.

Dial thermometers of types 621 to 681 are local thermometers with cramped-on ring case. Casing, immersion tube and connection are made of stainless steel. All devices comply with EN 13190 and meet class 1.

The devices are available in different nominal sizes from 63 to 160 mm. Due to the cramped casings, the thermometers are permanently sealed (IP65) and are ideally suited for casing fillings with silicone oil (optional).

We supply many different display ranges with measuring spans from 60 to 600 K. On the connection side, our standard range includes three different designs, six different connection types, various connection threads and numerous immersion tube lengths and diameters. In combination with each other, the versions allow optimal solutions for almost every application.
