Overview
RONGHUA INSTRUMENT HDM-250B Electronic Temperature Control Electric Mantle is specially designed for laboratory liquid heating equipment. It uses high temperature resistant and alkali-free fiberglass insulating material to seal the resistance wire in the insulating layer to weave into a hemispherical inner heating heater. With the advantages of large heating area, fast heating, good thermal insulation effect, no open flame, and not easy to bruise Glass utensils, it is a reliable heating equipment for laboratories in colleges and universities, petroleum, chemical, environmental protection and other industries.
Features
1. Adopt non-electric shock electronic voltage regulation circuit for more accurate temperature control
2. Long service life and wide temperature regulation range
3. Large heating area, fast heating
4. Good thermal insulation effect, no open flame
5. Glass ware not easily bruised
6. Can work continuously
Principle
The product uses high temperature resistant non-alkali fiberglass as insulating material, the resistance wire is sealed in the insulating layer, and then woven into a hemispherical inner heating heater. When in use, turn on the power switch, swirl/spin the temperature adjustment knob clockwise, the voltmeter shows the working voltage, and gradually heats up according to the required temperature. After reaching the required temperature, turn the adjustment knob counterclockwise to achieve thermostatic.
Applications
Colleges and universities, laboratories in petroleum, chemical, environmental protection and other industries
Standards
Voltage standard:~ 220V +/- 10%
Steps
1. Turn on the power switch
2. Clockwise swirl/spin temperature adjustment knob
3. Observe the voltmeter to display the working voltage
4. Gradually heat up according to the required temperature
5. After reaching the required temperature, turn the adjustment knob counterclockwise to achieve thermostatic
Notice
• When using it for the first time, slowly heat up. Turn off the power after seeing the raw white smoke. After the smoke is scattered, power on and heat up. Repeat several times until it is powered on and smoke-free.
• No flammable, explosive, corrosive liquids or gases can enter the Electric Mantle
• Relative working environment humidity does not exceed 85%
The product must be grounded
• When storing, it should be dried and not damp
• If there is moisture, you should pay attention to induction electricity when using it, do not touch it with your hands, and restore the insulation performance after drying
