The WK-302/25M (IEC) is a laboratory grade temperature control system that includes a temperature controller, an analog indicator, and a remote sensing probe. The controller features a combination of proportional-integral-derivative (PID) control, one-touch setup of parameters, and easy-to-understand operation. It also offers a range of features designed specifically for laboratory applications such as two-step temperature setting, easy calibration, and dual-level over-temperature protection. The analog indicator offers a four-digit backlit LCD display with adjustable brightness, temperature unit selectable between Fahrenheit or Celsius, and a selectable temperature span for accurate control. The remote sensing probe can be attached to the controller with a cable for accurate temperature measurements.
