The Isotech Small Hot Plate surface probe calibrator 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 temperature sensor can be placed alongside, and the two compared.

Good thermal contact is ensured by the flat disk, which 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 hot plate temperature probe's surface.

A protective cover that can fit over the block is included, along with a comprehensive handbook. The Hot Plate surface temperature sensor calibrator can be supplied configured for Fahrenheit operation; please specify on order.

The temperature range for this flat-surface temperature sensor is from 50 to 350°C, which is set by an advanced, but easy to use, temperature controller. The controller has been upgraded for 0.01 resolution below 100°C (0.1° above 100°). A PC interface is included with this hot plate temperature probe, along with an RS232 interface and Windows software.
