The stainless steel temperature-controlled electric hot plate adopts thick high-temperature resistant stainless steel plate as heating surface. The heating elements are fully enclosed and wrapped in insulation layers, with thermal insulation filling inside the heater and a stainless steel protective cover on top. It resists deformation under high heat and corrosion from acid & alkali splashes, achieving ultra-high thermal efficiency with over 35% power saving. Advantages: energy-saving, lightweight, safe, uniform heating, high efficiency, open-flame free. Compatible with flasks, beakers, Erlenmeyer flasks, widely used in scientific research, chemical, petroleum and pharmaceutical laboratories.

1. Housing stamped from premium cold-rolled steel sheet with electrostatic spray coating surface treatment.
2. Heating surface made of stainless steel or cast steel with anti-corrosion surface finishing.
3. Fully enclosed heating tray, flameless, fast temperature rise, stable and safe operation.
4. Two control versions available: electronic voltage regulation type or intelligent PID temperature control type.
5. Intelligent hot plate equipped with dual temperature sensors, capable of measuring both sample and plate surface temperatures to meet diversified lab test requirements.

Suitable for laboratories of industrial & mining enterprises, medical hygiene, environmental protection, biochemistry and scientific research institutes for chemical analysis, physical measurement, thermal treatment, sample baking, drying and various thermal testing experiments.

Electric hot plates are widely used across manufacturing and daily scenarios, including floor heating, electric water kettles and constant-temperature maintenance for laboratory test environments.

4.1 Pre-operation Degreasing Treatment

1. Connect power supply and turn on main power switch.
2. Glass fiber base contains residual surface grease. Heat up slowly until white smoke emerges, then cut off power. Repeat the cycle several times after smoke dissipates to fully volatilize grease. The plate surface will turn brown then back to off-white; slight yellow discoloration on the edge without heating elements is normal. The unit is ready for formal use after full degreasing.

4.2 Formal Operating Steps

1. Place test samples on the heating surface.
2. Switch on power supply.
3. Start heating with fixed gear; switch to adjustable voltage gear once approaching target temperature. Rotate voltage knob freely to fine-tune temperature to required value.

1. This product has reliable insulation performance, but glass fiber absorbs moisture easily. Store in well-ventilated dry areas when idle.
2. If dampened, do not touch the unit by hand when restarting. Heat up gradually to fully dry internal components before formal operation.

Pressure-sensitive adhesive bonding is applicable on flat, smooth workpiece surfaces.

• Max continuous operating temperature of pressure-sensitive adhesive: 150℃; instantaneous peak temperature: 230℃.
• Applicable only when power density ≤ 0.9W/cm².
• Silicone rubber heaters coated with pressure-sensitive adhesive should be used within half a year after factory shipment to avoid degraded adhesive performance.
• Small workpieces can be prefabricated and vulcanized at factory to maximize the service life of heating plates.
