ELECTROTHERMAL HEATING TAPE is the answer to a myriad of heating problems in the lab-oratory and production plant. Its flexible and elastic qualities enable even heating of any object

regardless of shape. Simply wrap the tape around the object to be heated and turn on the "juice."Any suitable control device such as a variable auto-transformer, rheostat or other energy regulator maybe used for power.

The Powerstat Variable Transformer-pictured in tape set-up above-provides an excellent source

of energy. Perfect heat control may be attained by turning the voltage regulator dial atop the trans-former.R42-519 Uninsulated Heating Tape. Transparency R42-519 Heating Tape-Insulated on One Side.allows viewing substance being heated Confines heat thereby minimizing loss.
