983

The small hot plate 983 is a lightweight portable calibration system designed for surface mounted sensors. The flat surface plate is made from precision-machined Aluminium. The sensor to be tested is simply placed on the surface, for higher accuracy a calibrated surface sensor can be placed alongside and the two compared.

Good thermal contact is ensured by the flat disc that is recessed to allow the optional use of a heat transfer paste or fluid. Uniform heat distribution is achieved with a flat spiral heater clamped to an integrating block below the surface of the plate. The typical accuracy that can be achieved is 1°C but this will be influenced by the type of sensor to be calibrated.

The internal control sensor is located immediately below the plate’s surface. 

A protective cover that can fit over the block is included along with a comprehensive handbook. 

The temperature range is from 35°C to 350°C, which is set by an advanced, but easy to use temperature controller. The controller has 0.01 resolution below 100°C (0.1°C above 100°C).
