When the subject turns to the professional measurement of temperature, a name which has become synonymous around the world for industrial thermometers inevitably comes up: Sika-Thermometer. That shouldn't be a surprise because the family run business in Hesse has been proving their competence in the manufacture of thermometers made to technical specifications of users in the industry for decades.?This is a household thermometer for use outside, made to industrial standards. The glass capillary is set in a solid, V-shaped aluminium housing with a polished, gold coloured anodised surface. The numerals of the measurement zone are printed indelibly in black into the anodised layer on the right-hand scale. The housing can be turned by hand to any position due to the fact it is rotatably mounted on the wall bracket.
