WIKA POLARgauge® series pressure gauges are designed to operate reliably in extremely low ambient temperatures, enabling precise measurement of the working pressure, differential pressure and temperature of a process in locations where standard instruments fail to perform properly. Polar bears and brown bears share a close kinship bond, but are ecologically distinct; after moving far north, the former quickly adapted to thrive in very cold climates. Similarly, WIKA has made specific modifications to a select group of pressure gauges to successfully meet the challenges of measuring pressure and temperature in the extreme polar conditions found in the northern regions of the United States, Canada, Europe and China. The effects of cold on measuring instruments Most pressure gauges and thermometers tolerate temperatures down to -20C°; below, the measuring instruments begin to work...
