Drying box and thermostat use methods and precautions

Drying ovens are used for dry and dry heat sterilization of items, and incubators are used for the cultivation of microorganisms and biological materials. The structure and usage of these two instruments are similar. The use temperature range of the drying oven is 50~250°C. The common fan type electric heating is used to accelerate the temperature rise. The maximum operating temperature of the incubator is 60°C.

1. Instructions
(1) Insert the thermometer into the seat (in the middle of the top bleed adjuster).
(2) Plug the power plug into a power outlet.
(3) Turn the head of the heating wire group to the 1 or 2 position (depending on the required temperature). At this time, the blower can be turned on to promote hot air convection. After the group of electric heating wires is turned on, the red indicator light is on.
(4) Observe the thermometer. When the thermometer temperature will reach the required temperature, adjust the automatic temperature control knob, so that the green indicator light just shines, and then observe the thermometer and indicator light after ten minutes. If the temperature on the thermometer exceeds the need, and the red indicator light is still on, then Turn the automatic temperature control knob slightly counter-clockwise until the temperature is constant at the required temperature. The indicator turns red and green. The thermostat knob is on the upper left side of the front of the case. Its scale plate cannot be used as a temperature standard indicator and can only be used as a marker for adjustment.
(5) In the constant temperature process, if there is no need for three groups of heating wires to generate heat simultaneously, only one set of heating wires may be turned on. The more open groups, the faster the temperature rises.
(6) After working for a certain period of time, the top central deflation regulator can be opened to vent the moisture, and the blower can also be turned on.
(7) After use, switch all the heating wire grouping switches off and turn the knob of the automatic thermostat counterclockwise to zero.
(8) Unplug the power plug.

2. Precautions
(1) Check the power supply before use, and have a good ground.
(2) There should be no explosion-proof equipment in the drying oven. Do not heat flammable materials and volatile materials in the box. Do not place flammable items near the cabinet.
(3) The inside of the box should be kept clean, and the ware should not be rusted, otherwise it will affect the cleanliness of the glassware.
(4) It should be monitored at regular intervals during use to avoid affecting the use of temperature or accidents.
(5) Blower motor bearings should be refueled once every six months.
(6) Do not twist the temperature sensor inside the box. Avoid touching the temperature sensor when placing items. Otherwise, the temperature is unstable.
(7) Cut off the power supply during maintenance.
