SD4 Thermocouple Sensor

SD4 Type T

Ellab thermocouple sensors for thermal validation and mapping, are made with superior quality materials that allows for high accuracy, stable measuring, and fast response times.

The SD4 type T thermocouple sensor has a temperature range of -20 to +135 °C, with an unmatched accuracy of <0.2 °C (calibrated  ± 0.05 °C), and a USB plug that saves calibration constants. The design of the SD4 thermocouple’s tip completely seals the sensor and provides 4 measuring points that can easily identify cold and hot zones. The thermocouple sensor functions with the wired Thermal Validation Syste E-Val™ Pro which can handle up to 120 channels.
