Constant temperature heating platform with precise temperature control & non-standard customization. We have 10 years of design and manufacturing experience. Modular structure, stable temperature accuracy. Equipped with original Yudian PID intelligent digital temperature controller, solid-state SSR relay and stainless steel heating tubes for easy maintenance and low failure rate.

1. Original Yudian PID intelligent digital temperature control system with high precision, safe and simple operation.
2. High-quality solid-state SSR relay with service life 100 times longer than ordinary contact relays. Fast response, high reliability, no operating noise, shock resistance, and excellent moisture-proof, mildew-proof and anti-corrosion performance.
3. Multiple high-grade stainless steel heating tubes filled with nichrome wire. Superior thermal conductivity, long service life, convenient maintenance and low failure rate.
4. Solid pure aluminum plate with high thermal conductivity and even heat distribution. Working efficiency is 5~6 times higher than conventional furnaces, and no deformation occurs under long-time high-temperature operation.
5. Housing made entirely of SUS304 stainless steel. No paint peeling or rusting under ordinary working environments.
6. The control cabinet is equipped with cooling fans and air vents to prevent overheating of internal components even under extreme working conditions.

1. Soldering and rework of aluminum substrates and LED chips in the LED industry.
2. Constant-temperature heating for glue dispensing and potting in all electronics industries.
3. Preheating and baking of electronic components.
4. Drying and baking of test samples across all industrial sectors.
5. Essential heating equipment for biological, genetic, environmental protection, biochemical, analytical and educational laboratories.

1. Place the unit on a flat, heat-resistant workbench. Do not cover or touch the heating zone during operation to avoid fire or personal injury.
2. Do not operate near flammable, explosive or combustible materials.
3. Cut off the power supply and wait until the plate cools down to room temperature before moving the equipment.
4. Always turn off the power when not in use to avoid accidents.
5. Continuous working time shall not exceed 12 hours.
6. Connect the power cord properly to the protective earth for personal safety.
7. Slight yellow discoloration on the metal surface after long high-temperature heating is a normal material characteristic.
8. Avoid contact with strong acids, alkalis and corrosive chemicals to prevent metal corrosion.
9. This device is not waterproof; keep it away from moisture.

4.1 Working Environment

• Power supply: Single-phase AC220V
• Ambient temperature: 0~55℃
• Humidity: below 90%RH, no condensation

4.2 Temperature Setting

1. Short press the * parameter key for 0.5s to enter temperature setting mode. One digit will flash. Use arrow keys to modify values and shift positions. Short press the * key again to save and exit. Settings will be stored permanently even after power off.
2. The 4-digit digital display supports decimal shifting. Adjust digits with up/down keys, then short press the parameter key to save all values.
3. Temporary overshoot before temperature stabilization is normal. Wait until the reading stabilizes before starting the experiment.

4.3 Basic Operation

1. Turn on the main switch. Solid red light means continuous heating; flashing light means approaching target temperature; intermittent flash means constant temperature is reached.
2. Upper PV window = measured actual temperature; lower SV window = preset target temperature.
3. Up/down arrow keys adjust the value; left arrow moves the decimal point.
4. No extra confirmation is required; the unit will automatically maintain the set temperature.

4.4 Temperature Offset Calibration

If there is deviation between displayed reading and actual plate temperature:

1. Long press the * key until “SHP” appears, then keep pressing until “SCB” is shown.
2. Use up/down keys to input positive or negative offset value.
3. Long press the parameter key again to save and exit.

Example: If the actual temperature is 10℃ lower than the reading, set PB -10.0; if 10℃ higher, set PB +10.0. All factory parameters are pre-calibrated and generally do not need user modification.

1. No power on startup: Check power plug and fuse.
2. Display value unchanged, no heating: Heating element is broken; please contact us for replacement.
3. High reading on upper window with “HHHH” or “LLL” on lower window: Thermocouple open circuit or controller failure.
