Product Details

A ZNHW-II HEATER LCD modelIntelligent digital display electric heating sleeveCharacteristics:

　　The ZNHW-II electric heating sleeve is made of alkali free glass fiber as insulation material, with Cr20Ni80 alloy wire spring installed in it. It is insulated by a hemispherical insulation body formed by vacuum shaping with aluminum silicate cotton. The shell is injection molded in one go, and the upper cover adopts electrostatic spraying technology. Due to the use of spherical heating, the heating area of the container can reach more than 60%. The temperature control is controlled by a computer chip as the main control unit, using multiple digital filtering circuits, fuzzy PID control algorithm, self-tuning function, with high measurement accuracy, low temperature flushing, single key touch operation, dual screen display, internal and external thermocouple temperature measurement, thyristor control output,~160-240V wide voltage power supply, and has a break protection function. It has fast temperature rise, high temperature, easy operation, and durability. Durable characteristics. It is an ideal instrument for conducting temperature control and heating tests.

Two ZNHW-II HEATER LCD modelsIntelligent digital display electric heating sleeveInstructions for Use:

　1. Insert the power supply to 220V and turn on the power switch. The display window shows "K", and the setting window displays the word "400". This appliance is equipped with a K-type thermocouple to control the temperature at 400 ℃. After 3 seconds, the display window shows room temperature, and the setting window displays the last set temperature value.

2. Single key operation, press the set plus "▲" or set minus "▼" key without releasing it, to quickly set the desired heating temperature, such as 100 ℃. When the green light is on, it indicates heating, and when the green light is off, it indicates stopping. The microcomputer will determine the heating amount based on the temperature difference between the set temperature and the current temperature, ensuring that there is no temperature shock and that the heating is done in one go. It will also maintain a balance of supply and heat dissipation under a temperature difference of ± 1 ℃ between the set value and the displayed value, making the heating process easy to complete.

3. There is a rubber plug at the bottom left of the electric heating sleeve, which is used to protect the external thermocouple socket from rust and to conduct the internal wires. If unplugged, the internal probe will disconnect and the machine will stop working. If using an external thermocouple, the plug should be removed and stored. Insert the external thermocouple plug into the socket and lock the gong nut, then place the stainless steel probe in the solution for temperature control heating.

4. The appliance is equipped with a break protection function. When the thermocouple connection is poor and the display window shows "1" or "hhhh" on the hundred level, the green light will turn off and the appliance will stop heating. It needs to be checked before use.

5. Self setting function. Activating the self setting function can shorten the heating time, reduce the flushing temperature, and achieve good balance when there is no regularity between different heating stages or heating power and the amount of solution. However, after changing the heating medium or heating conditions, the self setting should be reset.

6. Start self-tuning: Press and hold the shift key "?" for 5 seconds, and the setting window number will flash to enter the self-tuning state. After three temperature pulses, the number will stop flashing, indicating that the self-tuning is complete and can be used. However, self-tuning needs to be used at the beginning of heating, and the self-tuning performed midway may not be accurate.

Three ZNHW-II LCD modelsIntelligent digital display electric heating sleevePrecautions：

　　 1. The instrument should have a good grounding.

2. When in use, it is normal for white smoke and odor to emerge from the sleeve, and for the color to change from white to brown and then back to white. Due to the presence of oil and other compounds in the production process of fiberglass, it should be placed in a well ventilated area and can be used normally after a few minutes of disappearance.

When using an electric heating sleeve with a capacity of over 3.3000ml, there may be a squeaking sound due to differences in the furnace wire structure and related to the controllable silicon voltage pulse signal. You can use it with confidence.

When liquid overflows into the sleeve, please quickly turn off the power, place the electric heating sleeve in a ventilated place, and wait for it to dry before use to avoid the danger of electric leakage or electrical short circuit.

When not in use for a long time, please store the electric heating sleeve in a dry and non corrosive gas place.

6. Please do not use empty heating or dry burning.

When the environmental humidity is relatively high, there may be induced electricity transmitted through the insulation layer to the shell. Please ground the wire and pay attention to ventilation.

If there are any differences in the content of this manual due to improvements made to the product or the products mentioned in this manual, no further notice will be given.
