Temperature Controller, Digital, 2-Stage, Wired (Ranco)
Now you can easily control two different temperature regulating devices. This all new, two-stage controller comes pre-wired with dual AC outlets. One outlet is controlled by one relay, the other by a second relay. The most common application is to use one stage to heat and the other to cool. This means you can simultaneously control a heater and a cooling device, never having to manually switch between heating and cooling modes.
This nifty device allows you to precisely control the temperature of your fermentation or the temperature of your mash.
To control ferment temperatures you can place the temperature probe inside the space that is being cooled or heated (often a refrigerator) or you can place the probe directly into the ferment using a thermowell stopper.
The unit features an adjustable differential down to within one degree. This means you can precisely control an environment to within one degree of your set point.
The included sensor probe monitors the temperature while the digital readout displays it in either Fahrenheit or Celsius. The sensor probe is 1/4 in diameter and works well with thermowell stoppers and couplers.
Temperature Range of -30 to 220F.
