Type 271-291 BF Vibration Damped Version

The original SIKA thermometer with high-quality V-shaped aluminium casing, smoothly polished on all sides, anodised in golden colour. The numbers of the display range are printed in black on the right-hand side of the scale under the anodised layer. The print is thus permanently and indissolubly fixed in the anodised layer.

Our thermometer is available as standard in three nominal sizes, each in straight or angled 90° version and many display ranges from -30...50 °C to 0...250 °C. In addition, immersion tubes optionally made of brass, steel, stainless steel, special brass or copper nickel alloy and a variety of selectable connection types and threads. Our standard range of industrial thermometers contains a total of more than 17,000 different variants.
