This LCD dual display universal temperature controller with 1 degree resolution can be used as PID temperature controller, on/off temperature controller, or simply as a thermometer/pyrometer with alarm output. It offers great value for its price, as it is accurate, smart, and reliable. It is one of the smallest 1/32 DIN PID controllers on the market and the perfect unit for hobbyists to upgrade their brewer, incubator, espresso machine or glass kiln and professionals in industrial use. The newly developed artificial intelligence enhanced PID algorithm and auto-tune function will control the temperature within one degree accuracy without complicated PID parameter fine tuning. This controller contains all the primary functions of an industrial grade PID controller but is also made simple for amateur use.

The PID control mode can maintain the temperature within one degree when properly tuned. The on/off control mode is useful for controlling refrigerator, motor, or solenoid valve that does not favor frequent switching. Users can set the target temperature and hysteresis band. It will work like a mechanical thermostat with higher accuracy and tighter temperature range. All the control modes can be set for either relay output or SSR control output by user. When using the SSR output, the relay output can be used as an alarm output.


  • LCD display, shows PV and SV at the same time.
  • Compact size, 1/32 DIN that is only 24x48x75mm (0.95 x 1.89 x3")
  • Artificial intelligence enhanced PID algorithm provides precise control
  • Auto-tune function can automatically find the best PID parameters
  • On/Off control mode for refrigerator, motor and solenoid valve control application
  • Supports 10 different types of commonly used temperature sensor inputs
  • Displays temperature in either Fahrenheit or Celsius
  • Output configuration can be set by user for either relay contactor or SSR control
