Overview
RONGHUA INSTRUMENT HDM-3000B 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 and weave it into a hemispherical inner heating heater. It has the advantages of large heating area, fast heating, good thermal insulation effect, no open flame, and not easy to bruise Glass utensils. It is suitable for laboratories in colleges and universities, petroleum, chemical, environmental protection and other industries. It is a reliable heating equipment.
Features
1. Adopting a non-electric shock electronic voltage regulation circuit, the temperature control is better than mechanical temperature regulation, and it has the advantages of long service life and wide temperature regulation range.
2. Easy to operate: After turning on the power switch, swirl/spin the temperature adjustment knob clockwise, the voltmeter displays the working voltage, and gradually heats up to the required temperature by turning the knob counterclockwise to achieve thermostatic.
Principle
Electric Mantle through high temperature resistant non-alkali fiberglass insulating material resistance wire sealing in the insulating layer, forming a hemispherical internal heating heater, after energizing the resistance wire heating, to achieve uniform heating of the liquid; electronic temperature control type using non-electric shock electronic voltage regulator circuit, by adjusting the voltage control temperature, to achieve accurate temperature control.
Applications
Colleges and universities, laboratories in petroleum, chemical, environmental protection and other industries
Steps
1. Turn on the power switch.
2. Swirl/spin the temperature adjustment knob clockwise, observe the working voltage displayed by the voltmeter, and gradually heat up to the desired temperature.
3. After reaching the required temperature, turn the adjustment knob counterclockwise to achieve thermostatic.
Notice
- When using it for the first time, because the surface of the fiberglass is coated with grease, it needs to be heated slowly. Turn off the power after seeing the raw white smoke, and then power on and heat up after the smoke is sprinkled. Repeat several times until it is powered on and smoke-free before it can be officially used.
- 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, keep drying during storage, and do not get damp; if there is moisture, pay attention to induction electricity when using, do not touch it with your hands, and restore the insulation performance after drying.
