Precision Uniform Temperature Heating Plate
Our uniform temperature heating plate is independently engineered in-house, equipped with imported temperature control systems and premium heating materials to deliver high-performance constant-temperature work platforms. It meets strict customer requirements for surface flatness, temperature uniformity, durability and long-term reliability. Custom heating surface dimensions are available upon request; customers can select standard PID temperature control or segmented programmable temperature control systems as needed.
The digital precision uniform temperature hot plate is engineered with top priority on thermal performance. It delivers accurate temperature control with built-in temperature deviation correction functions, ultra-flat working surfaces that resist permanent deformation after long-term operation, and outstanding surface temperature uniformity. It fully satisfies strict thermal requirements of microelectronics and high-precision manufacturing industries. Widely adopted and highly recognized by research institutes, universities and industrial enterprises worldwide.
Equipped with precision PID heating control system for rapid temperature ramp-up, temperature fluctuation ≤±0.1°C. Adopting special integrated aluminum alloy heating panel: temperature uniformity within working area ≤±1% (Model ET-303DU), surface flatness <0.3mm over 300×300mm (Model ET-303DU), maximum continuous operating temperature up to 480°C. The top surface features acid and alkali resistance, automatic PID parameter calculation, temperature deviation compensation and over-temperature power-off protection functions. Also applicable as LED heating plates.

3. General Product Introduction & Complete Operating Tutorial
Laboratory heating plate is a dedicated constant-temperature device for heating pretreatment of all kinds of analytical samples. Equipped with glass-ceramic working surface featuring superior corrosion resistance, ultra-smooth surface for easy wiping and cleaning. Large heating surface area supports batch sample processing. Split control design isolates the controller from corrosive acid fumes for safer and more comfortable operation. Platinum resistance sensor delivers precise temperature control, fast temperature rise and uniform heat distribution up to 400°C. Large LCD screen for intuitive temperature reading, with overheat warning light that turns bright red when surface temperature exceeds 50°C.
Step 1: Wiring Connection
Connect power cable and temperature sensor cable properly. Align the small connector with three concave positioning grooves, align the large connector with two concave grooves, fully insert the plug, then tighten the threaded lock nut to finish wiring.
Step 2: Power On
Plug in the power cord, toggle the power switch on the right side of the unit to turn on power. The controller will display current ambient temperature once powered up, boot process complete.
Step 3: Keypad Parameter Setting
Set Target Temperature: Press [Set] key → temperature digits flash → adjust value with Up/Down keys → switch digit position with Left/Right keys → press [Confirm] to save target temperature.
Example for 210°C: Adjust tens digit to “2” with Up/Down → press Right key → adjust units digit to “1” → press Confirm to finish.
Set Timing Duration: After temperature setup and confirmation, timing value will flash automatically. Adjust hour/minute/second digits via arrow keys, press Confirm to save timing value.
Example for 3 hours 20 minutes: Enter temperature setting page → Confirm to switch to timing page → adjust hour digit to “3” → Right key → minute digit to “2” → Confirm to finish.
Step 4: Preheating Process
Preheating greatly improves thermal stability and temperature uniformity of the heating plate. After finishing temperature and timing configuration, press the [Start] key to activate heating. Recommended preheating duration: 30 minutes ~ 1 hour. The red overheat warning light will flash continuously once surface temperature exceeds 50°C; avoid direct contact with hot surface during this period.
Step 5: Run Sample Experiment & Post-Operation Maintenance
- After preheating completes, place sample vessels onto the heating surface to start experiment.
- When experiment finishes, press [Stop] to halt heating. Wait until the plate fully cools down to ambient temperature, then cut off main power supply.
- Wipe the entire working surface clean with a damp cloth, remove all liquid droplets, residues and contaminants before storage.
- Place sample digestion bottles or other labware onto the clean heating plate surface.
Reconnect power and flip the power switch; indicator light will turn on to show working status, with audio overheat alarm triggered under high temperature conditions. Adjust temperature control knob to reach target temperature; a full-time operator must supervise the equipment while heating is active. After all testing work completes, turn off the power switch and disconnect the mains power supply.
