The optical glass thermometer
The optical glass thermometer is a temperature gauge with liquid expansion (mercury, colored organic liquid or Isopenthane) which allows accurate measure of temperatures between +-200°C and 650°C.
The optical glass was conceived in shape of magnifying glass, which permits:
- An optimum precision in the reading
- A fast and easy control,and even at a distance of 5 meters
Accuracy, durability, weatherproof, easy reading, the BERGER optical glass temperature gauge, petrochemical type, provides a large working service, with no maintenance care needed.
