Overview
BENTING CZN-250ml Electric Mantle is specially designed for laboratory liquid heating equipment. It adopts high temperature resistant and alkali-free fiberglass insulating material, seals the resistance wire in the insulating layer, and weaves it into a hemispherical internal heating heater. It is mainly used in laboratories in colleges and universities, petroleum, chemical, environmental protection and other industries. It has the advantages of large heating area, fast heating, good thermal insulation effect, no open flame, and not easy to bruise Glass utensils.
Features
1. Using high temperature non-alkali fiberglass insulation material, resistance wire sealing in the insulating layer, safe and reliable.
2. Hemispherical internal heating heater design, large heating area, rapid heating.
3. Good thermal insulation effect, energy saving and high efficiency.
4. Operate without open flames to avoid the risk of fire.
5. Glass ware is not easily bruised to protect the experimental equipment.
Principle
Electric Mantle generates heat in the insulating layer through resistance wires, converts electrical energy into heat energy, and uniformly heats the liquid. The instrument control system monitors and adjusts the temperature in real time, the user can set the required temperature, and the equipment automatically heats up and enters the thermostatic state to ensure a stable heating process.
Applications
Colleges and universities, laboratories in petroleum, chemical, environmental protection and other industries
Standards
Voltage standard:~ 220V +/- 10%
Steps
1. Turn on the power supply, turn on the power switch, the upper row of the meter displays the studio temperature, and the lower row displays the set temperature.
2. Press the SET key to enter the temperature setting state, the data of the lower row of digital tubes flashes, press ▲ or ▲ to set the required temperature, and then press the SET key to save.
3. When the temperature rises, the finger light flickers on and off, and the display value is basically the same as the set value, it enters the thermostatic state.
4. Self-tuning function: Press the SET key for 5 seconds to enter the inner menu, select the AT parameters, set 1 to turn on self-tuning, the AT indicator light flashes, and the AT light goes out after the self-tuning is over.
5. Sensor error correction: Press the SET key for 5 seconds to enter the inner menu, select the SC parameter, press ▲ or ▲ to modify, the correction range is + 50 ° C to -50 ° C, and then press the SET key for 5 seconds to exit.
Notice
• During the self-tuning process, press the ▲ key for 5 seconds to stop the self-tuning, and the instrument is controlled according to the original PID parameters.
• Sensor error correction, ensure that the correction range is within + 50 ° C to -50 ° C.
• The maximum operating temperature of the equipment is 380 ° C, so avoid overheating.
• Power frequency must meet~ 220V +/- 10% standard to ensure safe operation.
