Heating, air conditioning & refrigeration temperature probes

In the heating industry, temperature probes are of key importance for measuring the temperature and controlling the heating.

In addition to the room temperature and the outside air temperature for weather-controlled regulation, flow and return temperatures in the heating circuit are measured.

However, temperatures must also be reliably measured in buffer storage tanks, boilers and heat pumps.

Testo Sensor is a specialist for qualified OEM temperature sensors that fulfil the difficult requirements in these applications.
