      FAQ

      I would like to perform a heating / cooling program where the temperature ramps from one set point to another over time. Are the PolyScience 28 L Refrigerated & Heated Circulating Baths capable of this?

      That depends on the controller used. Only the Advanced Programmable and Performance Programmable controllers can be programmed to perform ramps.
