Overview
RONGHUA INSTRUMENT DDF-1KW closed heater is widely used for sample baking, drying and other temperature tests, and is a required tool for biological, genetic, environmental protection, biochemical laboratories, analysis rooms, education and scientific research.
Features
1. The heater is made by a special molding process, with no warping at high temperatures.
2. The working panel is sprayed with materials, which has excellent anti-corrosion performance and uniform working surface temperature.
3. Heating up quickly and evenly, easy to operate, and safe to use.
Principle
After the power supply is turned on, the heating power is controlled by adjusting the voltage regulating potentiometer, the switch is turned on from 0 to 1, the indicator light is on, and the power of the heater from 1 to 5 is gradually increased to the maximum power to achieve uniform heating.
Steps
1. Please wipe the working surface clean before use, and do not allow water droplets, dirt, scale and other foreign matter residues on it.
2. Place sample bottles or other utensils.
3. Turn on the power supply, adjust the voltage regulating potentiometer, turn on the switch from 0 to 1, the indicator light is on, and the power of the 1 to 5 heater is increasing to the maximum power.
4, when the heater is in working condition, it should be taken care of by a special person.
5. After the work is completed, the potentiometer returns to 0 and cuts off the power supply.
6. After the working surface is chilled down, deal with it according to (1) requirements.
Notice
• Make sure the working surface is clean and free of residue before use
• Work status requires special care
• After work, the potentiometer must be returned to 0 and the power supply must be cut off
• After the working surface is chilled down, clean it
