Digital display constant temperature magnetic stirring adjustable temperature electric heating sleeve

1Digital display constant temperature magnetic stirring adjustable temperature electric heating sleeveProduct Introduction: This instrument is mainly used for liquid heating in laboratories of various colleges and universities, petrochemical, pharmaceutical, environmental protection and other industries. It uses alkali free glass fiber as insulation material, seals the resistance wire in the insulation layer, and then weaves it into a hemispherical internal heating heater. This product has the advantages of large heating area, fast temperature rise, good insulation effect, no open flame, and not easy to damage glassware. This product is an ideal heating equipment for laboratories and fine chemical units. IIDigital display constant temperature magnetic stirring adjustable temperature electric heating sleeveMain technical data Power:~220V ± 10% Operating temperature: 380 ℃ (surface temperature of heating element) Temperature control range: ambient temperature~380 ℃ Working time: continuous 3. Instructions for use: This product uses a non electric shock electronic voltage regulating circuit, which has the advantages of longer service life and temperature regulation compared to mechanical temperature regulation. This electric heating set has a voltage regulation function. By turning the knob, the indicator light will turn on or the voltmeter will change accordingly. By adjusting the knob, the voltage can be controlled to achieve a constant temperature. At the beginning, the voltage adjustment should not be too high, and the temperature should be slowly increased, otherwise excessive heating can easily damage the heater. 4、 Note 1: Due to the grease coating on the surface of the glass fiber, it should be slowly heated up during secondary use. After seeing white smoke, turn off the power, and after the smoke is dispersed, turn on the power to heat up. Repeat this process several times until the power is turned on, and then it can be used officially. 2. Flammable, explosive, corrosive liquids or gases cannot enter the sleeve. The relative working environment humidity of this instrument does not exceed 85%.
