1. A water bath is a hot bath method that uses water as a hot bath material. Since the water temperature is up to 100 ° C under standard atmospheric pressure, the maximum temperature of the water bath is 100 ° C. The method for treating the container product by using a water bath is: immersing the container requiring the water bath in a larger container containing water, and the container requiring the water bath should not be in direct contact with the larger container, and then heating the larger container on the heat source to the appropriate temperature The heating is stopped at the temperature, and the water bath container can be taken out after cooling. 2. Oil bath The heating of the oil bath is a thermal bath method using a high temperature heat transfer oil as a hot bath material. Commonly used oils are soybean oil, cottonseed oil, and the like. The maximum temperature of the oil bath is higher than that of the water bath, generally between 100 ° C and 250 ° C. The operation method of the oil bath is the same as that of the water bath, but the oil bath is especially cautious to prevent oil from overflowing or the oil bath is heated too high, causing fire. Temperature difference: The water bath temperature is room temperature - 100 ° C, and the oil bath temperature is 100 ° C - 300 ° C. Heating process: When heating, the substance to be heated is usually placed in a container, and the container is placed on a heat source. Some containers, such as glass containers and ceramic containers, if placed directly on a heat source, are often heated unevenly, and the temperature rises too fast, causing bursting. Or, due to poor heat transfer, the heated material is not heated uniformly. To this end, the heated container product entering the laboratory should be subjected to a thermal bath treatment. The so-called hot bath is to place the container in the hot bath material, let the temperature of the hot bath material slowly rise to a certain extent, and then let it cool slowly, thereby achieving a method of improving the heat transfer performance of the container and making the bottom of the container uniform. The hot bath methods commonly used in laboratories include water baths, oil baths, sand baths, and the like. Shangyu Star Equipment Co., Ltd.

With hand switch,can be switched to operating and
1. Set program: 1 pin is equivalent to 15 minutes. Determine desired start time and push down pins until desired
off time.
For instance, if you want electrical devices to work from 8:00am to 11:00am and from 13:00pm to 17:00pm, you
just need to put down allthe pins between the three period time.
2. Set the current time: Turning the dial clockwise until the arrow pointing to
current time.
For example,if now it is 8:00 am, please turn the dial and make sure the
arrow point to 8. (See the picture.)
3. Plug the electrical device directly into the timer. Make sure the electrical
device is power-on.
4. Plug the timer into electrical outlet and the electrical device will be work
according to the setting program.
Note: = Normal Ope n = Timing
Make sure the switch on the Timing position. If it
is on the [Normal Open" mode, the electrical device is
always power-on and the timer function no work.

Application:
1. To enable high-power electric appliances to run automatically at off-peak time if there is different electricity
price according to different periods of time in some areas.
2. To use for electric appliances which need time control, such as water heaters, air conditioners, drinking
fountains, rice cookers, advertising lights and so on.
3. To control the charging time. For example, battery of electric bikes or mobile phones, storage batteries, etc.
4. Occasions which need switch on/off frequently, like interval spray irrigation for flowersand lawn, cyclical
adding oxygen to fish jar, fountains and so on.
5. Home safety precautions and lighting.
