With a temperature range of 35 to 350°C and stabilization time of just 10 minutes, the Isotech Model 938 small hot plate offers a lightweight, portable calibration system designed for surface mounted sensors. The temperature range is set using an advanced, yet easy-to-use, temperature controller which features 0.01 resolution below 100°C (0.1° above 100°C). Depending on sensors and method of use, the typical uncertainty is 1°C. For higher accuracy, a calibrated surface sensor can be placed alongside the sensor under test.
Proper thermal contact is ensured by the Isotech Model 938's recessed flat disc which allows the optional use of a heat transfer plate or fluid. Uniform heat distribution is achieved with a flat spiral heater clamped to an integrating block below the surface of the plate. A protective cover that can fit over the block of the Isotech small hot plate is included. Additionally, a PC interface and RS-232 converter are both included standard and are to be paired with the Windows software that is also included for further data analysis.
