The use of heating plate for laboratory should follow the corresponding specifications

The heating plate used in the laboratory adopts nano-level thermal energy technology, no mechanical heater parts, no magnetic field interference, dry burning, fast heating, energy saving and environmental protection, the table is made of glass-ceramics, acid-resistant and alkal-resistant, easy to clean, and converts electric energy into heat energy to heat objects. Is a form of electricity utilization. Compared with general fuel heating, electric heating can obtain a higher temperature (such as arc heating, the temperature can reach more than 3000℃), easy to achieve automatic temperature control and remote control.

The heating plate in laboratory is made of glass and ceramic with good chemical stability, which has the effect of safe heating and constant temperature control. The heating plate which is widely used in laboratory has a high safety system, including fixed safety circuit, overheat display and error display. A contact electronic thermometer can also be installed in the heating plate, which can achieve high precision temperature control effect. The three characteristics of the laboratory heating plate are functionality, safety and durability.

The high frequency and high current flow direction of the heating plate used in the laboratory is wound into a ring or other shape (usually made of red copper tube). Thus, a strong magnetic beam with instantaneous changes in polarity will be generated in the coil. If heated objects such as metals are placed in the coil, the magnetic beam will run through the heated object. In the interior of the heated object, the direction opposite to the heating current will generate a large eddy current corresponding to it. Because there is resistance in the heated object, a lot of joule heat is generated, causing the object's own temperature to rise rapidly. To achieve the purpose of heating all metal materials.

The use of heating plate for laboratory shall follow the corresponding specifications, among which:

1. Fix the pole in the screw hole above the back of the agitator, adjust the height of the cross clip, fix the reaction bottle with the clip, insert the power supply ~ 220V, and open the switch.

Set according to add 2, temperature setting: "bring" or set minus "▼" key not to put, will quickly setting out the required heating temperature, such as: 100 ℃, green light said heating, green light goes out to stop, microcomputer based on the determined by the temperature difference size of set temperature and the current temperature and quantity of heat, ensure no WenChong warming in place at a time, and keep the set value and display values for heat balance of the + / - 1 ℃ temperature differences, make the heating process easily.

3. Self-setting function: when different heating sections or heating power and the amount of solution are irregular, the heating time zui is short, the heating temperature zui is small, and the balance zui is good. However, after changing the heating medium or heating conditions, the self-setting should be reset.

4, start self-setting: often press the shift key "?" 5 seconds, the setting window digital flicker enters the self-setting state, after three times of warm flush, the digital flicker stops, indicating that the self-setting is over and can be used, but the self-setting needs to be used at the initial heating, and the self-setting in the middle is not accurate.

5. There is a rubber plug below the instrument to protect the external thermocouple socket from corrosion and rust and to conduct the inner wire. If the plug is pulled out, the inner probe will be disconnected and the machine will stop working. If the external thermocouple should be removed and saved, the external thermocouple plug into the socket and lock the nut, and then put the stainless steel probe into the solution for temperature control heating.
