FAQ

Q1: What is the stirring speed range of this hotplate stirrer?
A1: The stirring speed ranges from 100 to 1500 RPM, suitable for different viscosity liquid mixing requirements in laboratories.

Q2: Can it heat and stir at the same time?
A2: Yes, it supports simultaneous heating and stirring functions, with independent control of temperature and speed for flexible operation.

Q3: What is the maximum load capacity for stirring?
A3: The maximum stirring load is 2L (for most models), please confirm the specific load parameter of your purchased model in the manual.

Q4: How to calibrate the temperature of the hotplate stirrer?
A4: It is pre-calibrated at the factory. For daily calibration, you can use a standard thermometer to measure the liquid temperature and adjust the offset value through the control panel.

Q5: Is the control panel waterproof?
A5: The control panel adopts a splash-proof design, which can resist accidental liquid splashing, but do not immerse the equipment in water.
