When protecting those in your care is a top priority, this Paraffin Thermometer is a good tool to have on your side. Melting paraffin can be tricky. When new, paraffin melting units operate within a temperature range of 125-134 degrees, with the ideal temperature for melting to be at about 130 degrees. Older units, most without built in temperature gauges, can heat unevenly or take longer to get up to melting heat. This thermometer lets clinicians take the guesswork out of paraffin treatments and avoid costly mistakes by having clients place body parts into paraffin baths that are too hot that it burns. The thermometer easily displays the temperature of the paraffin up to 22o degrees Fahrenheit. Simply thread the thermometer stem through the hole located at the bottom of the sleeve to act as a holder to protect hands. The 1″ diameter shatterproof lens is also magnified. At 5″ long, the thermometer is small and lightweight. After use, the thermometer will probably be hot to touch. Do not leave the thermometer in the melting unit when melting paraffin as damage to the lens may occur. To clean, handwash the thermometer only. Do not immerse it in water or place in the dishwasher.
