Laboratory Electric Heating Plate
Laboratory electric heating plate adopts electrothermal alloy wire as heating element, mica soft board as insulation material, wrapped with thin metal sheets (aluminum plate, stainless steel plate etc.) for heating. Metal tubular heating elements can be cast, welded or embedded into aluminum trays/aluminum plates to form electric heating plates of various shapes.
1. Product Features
- Temperature Controller: Original Yudian PID artificial intelligent digital temperature controller with high precision, safe, simple and intuitive operation.
- High-quality solid state relay (SSR): Service life 100 times longer than ordinary contact relays; fast response, high reliability, no operating noise, shock & vibration resistant, excellent moisture, mildew and corrosion resistance.
- Multiple high-grade stainless steel heating tubes with long service life, filled with imported high-purity magnesium oxide, Ni80Cr20 nichrome heating wire, ultra-high thermal conductivity, low failure rate, convenient maintenance.
- Heating panel made of aluminum alloy with outstanding thermal conductivity, fast heating speed, uniform temperature distribution, high efficiency (5–6 times that of ordinary furnaces), no deformation under long-term high temperature operation.
- Whole housing made of imported SUS304 stainless steel; no paint peeling or rust under normal working environments.
Built-in cooling fan and heat dissipation vents in control cabinet to prevent overheating of internal components under extreme working conditions.

3. Operation Steps
- Connect power supply and turn on power switch; green power indicator stays lit to signal power input.
- Turn on heating switch to start operation. Solid red heating lamp = continuous heating; flashing red lamp = constant temperature holding with intermittent heating.
- After use, turn off heating switch first. Green power light remains on as a warning — do not touch hot surface. Wait at least 1 hour for full cooling before cutting main power.
4. Component Introduction
- Aluminum platform: 20mm thick high-grade mirror-finish aluminum alloy, fixed by 4 screws for easy disassembly, convenient for heating tube maintenance & replacement.
- SUS304 stainless steel support posts to keep the aluminum platform perfectly horizontal.
- Heating switch: activate to heat up and reach constant temperature.
- Heating indicator light: on during heating; steady = target temp unreached, flash = constant temperature state.
- Power indicator: always lit when 220V AC power is connected; off means no power supply.
- Intelligent PID temperature controller: microcomputer fuzzy logic auto-tuning, dual digital tube display with decimal point, control accuracy ±0.2℃, stable performance, design service life 10 years.
- Parameter setting key: long press 3s to enter parameter menu, refer to controller manual for details.
- Decimal shift key: shift decimal digit for value adjustment, see manual for operation.
- Down adjustment key: decrease set value.
- Up adjustment key: increase set value.
5. Safety Precautions
- Place the unit on a flat horizontal desktop; the aluminum platform is calibrated with a level gauge at factory, no readjustment needed.
- Do not block cabinet ventilation slots to avoid poor heat dissipation. Never insert metal objects into vents to prevent electric shock hazard.
- Avoid long-term operation in highly humid or corrosive environments which will damage the equipment surface.
- Use a grounded 3-prong socket with leakage protection switch. Ground wire eliminates induced electricity for full operator safety.
6. Maintenance & Care Instructions
- Rated power supply: 220V AC, must use grounded three-hole socket and leakage circuit breaker. Fully insert power plug into rear port to avoid poor contact and arcing damage.
- Non-professional personnel shall not open the cabinet or modify internal wiring.
- Forbid use near flammable, explosive and combustible materials.
- Never touch hot heating surface directly to prevent scald injury.
- Cut off power completely when not in use to avoid safety accidents.
- Disconnect power and cool to ambient temperature fully before moving the heating platform.
- Do not block side air intake vents of the air cooling system.
- Unplug power cord before replacing fuse to prevent electric shock risk.
- Cleaning: Use standard detergent and industrial water. For heavy solid residue, polish lightly with fine sandpaper.
