JK7500C is easy to use and lightweight. Anyone can learn how to use it in less than 15 minutes. With a temperature range of 395 °C, it is ideal for calibrating RTDs, thermocouples, and small bimetallic thermometers in the field.

Connect the AC with the handheld dry block, turn on the switch (note that the wells are fixed and not interchangeable), set the temperature with the control panel buttons, and insert the probe into the well of the appropriate size. Compare your unit reading to the displayed temperature or an external reference temperature, and the difference is the unit's error. JK7500C is equipped with a precise temperature controller with a display resolution of 0.1°C, an accuracy of ± 0.25 °C, a stability of ± 0.1 °C, and a stabilization time of only five minutes.
