How to maintain and use the electric thermostat blast drying oven?
a) The electric heating constant temperature drying oven consumes a relatively large current. Therefore, the power cord, knife switch, fuse, plug, socket, etc. it uses must have sufficient capacity. For safety, the case should be grounded.
(2) For the old-fashioned electric thermostat drying oven, a suitable mercury thermometer should be inserted into the jack in the center of the exhaust window at the top of the oven (or incubator). In order to observe the temperature inside the box at any time. The number pointed to by the thermostat knob is not the actual reading of the temperature inside the box. It is just the scale for memory when tempering. The temperature inside the box should be based on the indication of the thermometer.
The new type of electric heating box is intuitive because it does not require a mercury thermometer.
(3) The items placed in the box should not be excessive or over-squeezed. If the dried item is wet, open the venting window. When heated, the blower can be activated so that the water vapor is accelerated out of the tank. But don't let the blower run continuously for a long time, pay attention to proper rest.
(4) The drying box is kept at a constant temperature and is dried on the heat dissipation plate below the constant temperature room. Items cannot be placed to avoid rotting or causing burning.
(5) When the glassware is subjected to high-temperature dry heat sterilization, the temperature inside the box must be lowered before the door can be opened to prevent the glass from bursting due to cold.
(6) It is strictly forbidden to put flammable, explosive and volatile items into the box to avoid accidents.
(7) Water-isolated incubator, before heating and heating, a sufficient amount of water must be added to the water tank to indicate the “water stop†mark. In order to shorten the heating time, warm water having a temperature higher than the required temperature of about 4 ° C may be added (for example, a constant temperature of 37 ° C is required, and warm water of 41 ° C may be added).
(8) In the incubator or the water-proof incubator, any immersion-type electric heating pipe must be immersed in the electric heating pipe before being energized. It is absolutely not allowed to add water after power on. Otherwise, it is easy to burn the electric heating tube or damage the electric heating equipment.
(9) If you need to observe the items in the constant temperature room, you can open the outer door and observe it through the inner glass door. The number of opening the door should not be too much, so as not to affect the constant temperature.
