983 Hot Plate Surface Temperature Sensor Calibrator. Temperature range 50°C to 350°C.
Model 983 is a lightweight portable calibration system designed for surface mounted sensors.
The flat surface plate is made from precision-machined aluminum.
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.

• Low Cost Portable Hot Plate

• PC Interface and Software

• Stable to +/- 0.1°C

Good thermal contact is ensured by the flat disk 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 Hot Plate can be supplied configured for Fahrenheit operation, please specify on order.

The temperature range is from 50 to 350°C, which is set by an advanced, but easy to use temperature controller. The controller has been upgraded to have 0.01 resolution below 100°C (0.1° above 100°).
A PC interface is included as standard along with an RS232 interface and Windows software.
