First, the use of constant temperature oil (water) bath
When using, you must first add water (oil) to the pot, then turn on the power, then select the temperature you want. The green light indicates heating, indicating that the pot is heated. However, it is not possible to add too much water (oil) to avoid overflow when boiling. And pay attention to adding water (oil), can not make the electric heating tube leak out of the water (oil) surface, so as not to burn the electric heating tube, resulting in leakage.
Second, the series of constant temperature oil (water) bath
Principle: It is digital display temperature, touch switch setting, thermocouple temperature sensing, and error correction knob to adjust the error to ±1 °C. Its thermocouple (K sensor) transmits the temperature signal to the network. , generating a temperature measurement signal and a temperature control signal. The temperature measurement signal indicates that the digital tube displays the actual temperature, the temperature control signal triggers the thyristor control current, the green light indicates heating, and the red light indicates stop. The line uses electronic proportional control, with automatic compensation for the break protection function, and the control time is the shortest. By prematurely interrupting the power supply, to near rapid switching, precise temperature control.
Use: The method of using the digital oil water pot is the same as that of the digital water bath.
Third, the constant temperature oil (water) bath pot matters needing attention
1. In order to ensure safety, please connect the ground wire when using.
2. It is strictly forbidden to add water or oil to dry.
3. Because of the temperature difference between the water temperature and the temperature in the water pot, it is necessary to measure the temperature when the water temperature is in a stable state.
4. There is a sensor between the heating tubes. Do not bump. 
16MM Key Switches
In the past 30 years, our company has been striving to create a high-quality and high-reliability 16mm power key switch. In order to enhance the competitive advantage in the world, our company has dozens of imported advanced testing equipment and has a complete ISO 9001 quality management system. The series On Off Key Switch products are strictly screened and repeatedly tested to provide customers with reliable products for the purpose of making customers rely on our quality.
One of the the most competitive factor of our key lock switch is that we have design a bran-new modal, ie, S301 serious , which is the only exclusive security key switch in the switches industry. Furthermore, the voltage and electricity of 16MM key switches is stronger, could supply bigger equipment and machines, like Metal Switches, Automotive Switches, Rocker Switches and Slide Switches.
Quality assurance of our 16 mm key switch power lock: In order to meet the requirements of customers in Japan, Europe,the United States and the globe, our 16mm key switches have passed the European and American environmental protection RoHS certification, and can provide customers with a full range of key switch SGS material analysis report, UL certification and other Relevant third-party testing and certification.
