Correct operation of high temperature oil tanks and precautions
First, the product introduction: The high temperature oil tank improves the uneven oil temperature at each point in the oil bath tank, and at the same time increases the outer circulation interface and can be connected with the experimental equipment outside the oil tank. High temperature oil baths are widely used in distillation, drying, concentration, and impregnation of chemicals or biological products. The oil bath is an ideal equipment for laboratory technicians in various secondary technical colleges, environmental protection, scientific research, health, epidemic prevention, petroleum, metallurgy, chemical, medical and other units.

Second, the main features:
1. The box insulation material is made of high-quality glass fiber as the heat insulation material to ensure that there is no obvious temperature rise outside the box when the instrument is used at high temperature.
2, over temperature protection, over temperature buzzer prompt function.
3. Sensor fault code prompt function.
4, using microcomputer LCD temperature controller, a variety of working state with Chinese display function, accurate temperature control, simple operation.
5. The heater, fuel tank and circulation pump are all made of high quality stainless steel.
6. Display temperature and actual temperature error correction function.
7. The temperature controller has a temperature display and a constant temperature timing decrement display function.
8, circulating pump timing function, with dual functions of internal and external circulation.
Third, the use of:
1. Before installation, the high-temperature oil tank should be placed on a flat workbench. Check the appearance first: the appearance should be no damage, the appearance of the instrument is intact, the power cord is not damaged, the plug is intact, and the power switch is flexible. The single-phase three-pole plug is connected to the power cord of each device. The uppermost electrode of the plug is the grounding wire. The user must use a power socket with a safety ground.
2. Add an appropriate amount of oil to the fuel tank before powering on, preferably 5-8cm from the top cover. The choice of oil depends on the temperature of use: room temperature -150 ° C: methyl silicone oil; 100-250 ° C: phenyl silicone oil; 200-300 ° C: 350 # high temperature heat transfer oil.
3. Digital temperature control instrument setting and use:
(1) Turn on the power switch, the power indicator light is on, turn on the heating switch, the temperature controller lights up, wait about 20 seconds, the upper row shows the actual temperature inside the box, and the lower row shows the set temperature. Click the function button, the upper row displays sp, the lower row displays the set temperature, click â–³ or â–½ to select the working temperature, click the function button again, the upper row displays st, the lower row shows the time required to heat, click â–³ or â–½ to select the constant temperature timing If you do not need to set the time to 00.00, you can set it. Click the function key again to exit. At this time, it will run according to the set parameters.
(2) Put the reagent bottle to be heated in the box (if using external circulation, please connect the circulation tube before heating), open the circulation switch, and the oil will circulate in the tank to ensure the oil temperature at each point in the box. Uniformity.
(3) After the experiment is completed, first turn off the cycle switch, then set the temperature to 0, turn off the heating switch, and finally turn off the power switch and cut off the power.
Fourth, note:
1. Wear safety gloves when using to avoid burns.
2, the oil level can not be too high, so as not to overflow the electrical box damage components.
3. When using the oil bath, it must have a reliable grounding to ensure safe use.
4, the oil level is lower than the electric heating tube, do not use electricity to avoid the electric heating tube burst damage.
5. Regularly check whether the screws of each contact are loose. If it is loose, it should be tightened to keep the contact of each electrical contact good.
6, when the super constant temperature oil bath is used, it must be energized first, and dry burning is strictly prohibited.
