Features: 1.PTC HEATING PLATE: After electrifying, PTC quickly converts electric energy into heat energy, which is conducted to the surface of aluminum shell within 10S, and can be dried for a long time. 2.NO OPEN FLAME: The surface temperature is 200 and the cable length is 15cm. No open flame, no redness, no toxic and harmful gases, suitable for use in humid environment. 3.CERAMIC THERMOSTATIC: PTC heating element uses ceramic constant temperature heating technology to continuously output heat and work automatically at constant temperature. 4.INSULATION TEMPERATURE RESISTANT: PTC thermostat heating plate uses polyimide film to wrap the chip inside, which has insulation, temperature resistance and long term stable heating performance. 5.LONG SERVICE LIFE: Ceramic thermostatic plate can work continuously for 7x24 hours, and continuously provide heat source for more than 20,000 hours, meeting your needs.
