Featuring a durable 4-inch glass ceramic work plate (100 × 100 mm), the unit offers excellent resistance to strong acids, strong alkalis, and high temperatures while maintaining easy surface cleaning after solvent or reagent spills.\u003c\/p\u003e\n\u003cp\u003eThe heating plate provides a temperature range from room temperature up to 550 °C with 1 °C increments, ensuring accurate thermal control for various laboratory procedures. The integrated LCD display simultaneously shows both the set temperature and real-time temperature values, as well as timer settings, allowing clear and intuitive monitoring during operation.\u003c\/p\u003e\n\u003cp\u003eEquipped with a high-precision PT1000 external temperature sensor (±0.2 °C accuracy), the system enables precise temperature regulation for sensitive experiments. The timer function supports programmable heating from 1 minute to 99 hours 59 minutes, automatically stopping heating when the countdown finishes to protect samples from overheating.\u003c\/p\u003e\n\u003cp\u003eSafety is enhanced through multiple protective features including residual heat warning above 50 °C, overheating protection at 580 °C, and dual independent safety circuits that continuously monitor system status. If abnormal conditions such as sensor failure, overheating, or electrical faults occur, the device automatically stops heating and displays an error message.\u003c\/p\u003e\n\u003cp\u003eThe corrosion-resistant metal housing improves heat dissipation and durability, while the raised waterproof edge and drainage platform help prevent liquids from entering the internal electronics. With remote control capability for computer connection and preset safety temperature settings, the DHP4-550 digital heating plate provides a reliable and efficient heating solution for modern laboratory environments.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable border=\"1\" style=\"border-collapse: collapse; width: 90%;\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\"\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003eCat.No.\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\"\u003e8021502211 (Main Unit) \/ 8121502211 (Set)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003eWork Plate Dimension\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\"\u003e100 × 100 mm (4 inch)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003eWork Plate Material\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\"\u003eGlass ceramic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003eHeating Temperature Range\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\"\u003eRoom Temp. – 550 ℃, increment 1 ℃\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003eTemperature Display\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\"\u003eLCD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003eTime Display\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\"\u003eLCD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003eTemperature Control Accuracy\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\"\u003e±1 ℃ (\u0026lt;100 ℃) | ±1% (\u0026gt;100 ℃)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003eTemperature Display Accuracy\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\"\u003e0.1 ℃\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003eExternal Temperature Sensor\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\"\u003ePT1000 (accuracy ±0.2 ℃)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003e\"Hot\" Warning\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\"\u003e50 ℃\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003eOverheating Temperature Protection\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\"\u003e580 ℃\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003eHeating Position\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\"\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003eTimer Function\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\"\u003e1 min – 99 h 59 min\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003eProtection Class\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\"\u003eIP21\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003ePower\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\"\u003e430 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003eHeating Output\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\"\u003e410 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003eVoltage \/ Frequency\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\"\u003e100–120 \/ 200–240 V, 50 \/ 60 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003eDimension [W × D × H]\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\"\u003e270 × 175 × 108 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003eWeight\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\"\u003e1.8 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003ePermissible Ambient Temperature\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\"\u003e5 – 40 ℃\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003ePermissible Ambient Humidity\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\"\u003e80% RH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003eThe ceramic plate offers excellent corrosion resistance, capable of withstanding strong acids, strong alkalis, and high temperatures.
