Features

Applications:

Production facilities and warehouses - Monitoring of storage conditions and production processes in the temperature range -200 ° C to + 600 ° C.

Meteorology - COMET sensors together with COMET radiationshields are the ideal basis for weather stations for long-term weather, climate and air monitoring.

Healtcare and laboratories - -200 °C.

Industry and production - monitoring temperature and humidity in food, pharmaceutical, aerospace etc.

Food industry - Monitoring of critical processes according to the HACCP standard with the possibility of prompt notification of unforeseen events that could lead to the degradation of the goods.

Building management - Our instruments which measure temperature, humidity, atmospheric pressure and CO2 are an integral part of these industry-leading solutions.
