This controller uses two temperature probes for accurate home beer brewing system. L shape long probe is placed in the beer to accurately measure the liquid/beer temperature; the small probe is placed in the chiller (outside of the tank). This probe is to set the boundaries for heating and cooling, so that the chiller does not become too cold or too hot during the operation.

This dual-probe controller provides higher precision control compared to the single-probe controller. The single-probe controller has some limitations: If the probe is placed inside of the liquid, the outer layer of liquid might get too cold during cooling, because the liquid cools much slower than the air surrounding it. During heating, the outer layer of liquid might also get too hot. If the probe is placed in the chiller (outside of the tank), you may not know the true temperature of the beer inside because the fermentation is an exothermic process. This dual-probe controller is designed to solve this issue. For example, if you set the temperature of fermentation in 14C degrees, you can set the boundary (chiller temperature for probe 2) at 9C degrees. So the temperature in the chiller will never go lower than 9C degrees during the cooling process. In addition The controller equipped with high and low alarm set point that when the temperature reach to alarm set points, the controller start beeping and flashing.

The controller has two outputs. One for heating and another for cooling. Utilizing both cooling and heating device control, refrigerators can be controlled at specific temperatures regardless of the environmental climate.

This mini Temperature Controller is an excellent, reliable, accurate and convenient multifunction device when you need to control the temperature precisely and constantly. It’s suitable for all equipment which need to control one zone or two zone (separately) for heating or cooling mode.

It is an ideal solution for a wide range of professional applications to automatically control temperatures of up to -50 to 120 °C. It comes with two temperature sensors and manual.

Features:

2 relay and 2 sensors with 2 independent zones temperature controller.

2 zones (2 Heating mode, 2 Cooling mode or 1 Heating and 1 Cooling).
