The DM series mantles all feature an integral digital temperature controller linked by a sensor probe which is inserted directly into the flask. The liquid temp is shown on a clear LED display the desired temperature is set using a push button and potentiometer. The elements are insulated from the case by moulded silica powder to give excellent thermal insulation and very low case temperatures. A soft fibre glass woven mantle provides good impact protection and the close surface contact allows optimum heat transmission to the flask. Case contstruction - Steel, with chemically resistant coationg Thermal insulation - Moulded silica powder.
