DHP7-550 LCD Digital 7-Inch Timed Heating Hotplate

Product Features：

The ceramic heating plate offers excellent corrosion resistance, withstanding strong acids, strong alkalis, and high temperatures. It is easy to clean in the event of accidental spills of solvents, oils, or other contaminants.

The corrosion-resistant all-metal housing provides efficient heat dissipation and reliable fire protection.

An optimized fluid-guiding platform and raised spill-protection edge help prevent liquids from entering the unit and damaging internal electronic components.

The safety lock prevents accidental changes to the operating status.

A built-in buzzer provides an audible alert when a fault occurs or when the timer countdown is complete.

The residual heat warning function enhances operational safety. When the plate temperature exceeds 50°C, the display flashes “HOT” after heating is turned off. Even after the power is switched off, the “HOT” warning continues to flash, reminding users that the surface remains hot.

Two independent safety circuits continuously monitor the device. In the event of overheating or sensor failure, the unit displays an error and stops heating. In the event of a short circuit, the device automatically cuts off power to protect the operator.

The LCD screen clearly displays both set and real-time values for time and temperature, ensuring intuitive operation.

The built-in timer supports a setting range from 1 minute to 99 hours and 59 minutes. Heating stops automatically when the countdown ends, helping prevent thermal damage to samples.

Remote control functionality allows the unit to be connected to a computer for convenient operation.

The safety temperature limit can be set according to application requirements.
