Overview
RONGHUA INSTRUMENT HDM-500B Electronic Temperature Control Electric Mantle is a equipment specially designed for laboratory liquid heating. 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 widely used in laboratories in colleges and universities, petroleum, chemical, environmental protection and other industries.
Features
1. Adopt non-electric shock electronic voltage regulation circuit to achieve accurate temperature control; 2. Long service life and wide temperature regulation range; 3. Easy to operate, adjust voltage and temperature through knobs; 4. Large heating area, fast heating; 5. Good thermal insulation effect, no open flame; 6. Not easy to bruise Glass ware.
Principle
Electric Mantle through high temperature non-alkali fiberglass insulating layer sealing resistance wire, forming a hemispherical inner heat heater, the resistance wire heating after power, heat is evenly transferred to the heated liquid; electronic temperature control type using electric shock-free electronic voltage regulator circuit, the user through swirl/spin temperature adjustment knob control the operating voltage, temperature regulation and thermostatic function.
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 voltmeter display working voltage; 3. Gradually heat up as needed; 4. After reaching the required temperature, turn the adjustment knob counterclockwise to achieve thermostatic.
Notice
1. The first use needs to be slowly heated up, turn off the power after seeing the raw white smoke, power on and heat up after the smoke is scattered, and repeat several times until it is smoke-free before it can be officially used; 2. Electric Mantle cannot enter flammable, explosive, corrosive liquids or gases; 3. Relative working environment humidity does not exceed 85%; 4. Must be grounded, keep drying during storage to avoid moisture; 5. If there is moisture, pay attention to induction electricity when using, do not touch with hands, and restore insulation performance after drying.
