MEDUSA 3-DIGIT TEMPERATURE CONTROLLERS (DISCONTINUED)

Medusa temperature controllers accurately control either air or water temperatures between the range of 32 degrees Fahrenheit to 90 degrees Fahrenheit (0C-32C). The temperature range of the HC-150 and TC-250 make them especially suitable for aquarium use. The HC-150 controls a heater and a chiller and the TC-250 controls either a heater or a chiller while giving a continuous digital readout of the temperature. An audible alarm sounds when the temperature varies 3 degrees above or below the set point or if the temperature sensor fails. This feature sets Medusa controllers apart from other controllers by warning you before serious damage from high or low temperature occurs. Medusa controllers are simple to install. Just plug your heater and/or chiller into the receptacle on the bottom of the controller and program the desired aquarium temperature for complete temperature control. The PHC-300 has programmable differentials where more precise temperature control is required and controls both a heater and a chiller.

The 3-digit temperature control line is designed for applications that require higher accuracy than the 2-digit models.
