HH series electric heating constant temperature water bath is mainly used for distillation, drying, concentration, and temperature-sensitive chemicals or biological products in the laboratory. It can also be used for constant temperature heating and other temperature tests. It is biological, genetic, viral, aquatic, environmental, medical, An essential tool for health, laboratories, analysis rooms, and education and research.
Use and maintenance methods of HH series electric heating constant temperature water bath : Second, HH series electric heating constant temperature water bath use and maintenance:
(1) The appropriate amount of clean tap water must be added to the pot before use, or hot water can be added at the required temperature to shorten the heating time.
(2) Turn on the power and select the temperature.
When equipped with an electronic thermostat, adjust the “temperature knob†clockwise to the desired temperature. At this time, it is heated and the green indicator light is on. When heated to the desired temperature, the red indicator light is on, and it is at a constant temperature.
When equipped with a digital display header, the counter zui is a large number of ten digits, according to the operation The symbol is an increment, press operation The symbol is a subtraction. The traffic light changes as the temperature of the body changes. Similarly, the green light indicates that the heater is working and the red light is constant temperature.
The instrument must be heated and thermostated twice or more to achieve the correct temperature accuracy (must be closed after all capping and sealing).
(3) After the work is completed, put the temperature control knob and the increase/decrease device in the small value of zui, and cut off the power.
(4) If the water temperature in the pot is 100 ° C and used for boiling water distillation, adjust the knob to the end point.
(5) Do not add too much water to avoid overflowing the pot when boiling.
(6) The amount of water in the pot should not be less than one-half, and the heating tube should not be exposed to the water surface. In order to avoid burning, resulting in water leakage and leakage.
(7) The three-eye socket must be effectively grounded when the product is used.
