Thermaster Temperature Controller

The Thermaster is a fully automatic temperature controller which will operate without attention once set up. The enclosure is designed for surface mount making it suitable for operation at the point of use and is completely moisture proof sealed to IP65. It has a large clear display.

Easy to install; fitted with flying leads and is compatible with other electrical equipment. It has a simple relay operation allowing a volt free output if required.

The controller operates on 240V as standard, 110V available.

Probes are fully non-corrodable, deposit resistant and virtually unbreakable. They are supplied with 0·5m probe length with a 2m lead as standard, with longer lengths available to order.
