Application and maintenance of HH series electric thermostatic water bath

HH series electric constant temperature water bath is mainly used for distilling, drying, concentrating, warming chemicals or biological products in the laboratory, and also for constant temperature heating and other temperature tests It is a necessary tool for biology, genetics, viruses, aquatic products, environmental protection, medicine, health, laboratory, analysis room, education and scientific research HH series electric thermostatic water bath uses and maintenance methods: 2 HH series electric thermostatic water bath uses and maintenance: (1) when using, you must first add a proper amount of clean tap water into the pot, or add hot water according to 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 required temperature At this time, it is in the heating state, and the green indicator light is on When heating to the required temperature, the red indicator light is on, and this is a constant temperature state When equipped with a digital display header, the big digit of the counter Zui is ten digits, the operation symbol is an increase and the operation symbol is a decrease The traffic light changes with the temperature in the body Similarly, the green light indicates that the heater works, and the red light indicates constant temperature The instrument must be heated and constant temperature for more than two times to achieve the correct temperature accuracy (it can only be achieved after all covers and rings are sealed) (3) after the work is completed, turn the temperature control knob and the increaser to Zui low value, and cut off the power supply (4) if the water temperature in the pot is up to 100 ℃ for boiling water distillation, adjust the adjustment knob to the end point (5) do not add too much water to avoid the water overflowing outside the boiler when boiling; (6) the water in the boiler shall not be less than one-half, and the heating pipe shall not be exposed to the water In order to avoid burning, causing water leakage and electric leakage (7) the three socket must be effectively grounded when the product is used.
