Matsuo MQT series thermostats, available from ATC Semitec, are IP64 rated, have excellent repeatability (within +/-0.2K) and life cycles of up to one million operations.
The thermostats are said to outperform cheaper disc thermostats on every level and help to minimise costly maintenance calls.
They have a twin-bimetal system that is stress free and thus limits set-point drift and maximises cycle life.
They are suitable for anti-condensation/anti-frost applications where the sealed housing protects the contacts and can be supplied with accuracies as small as +/-1.5K with differentials down to 3K+/-1K.
Calibrations from -10/+110C are available.
