ZHT type automatic constant temperature electric heating sleeve

ZHTAutomatic TypeConstant temperature electric heating sleeve

1、 Practical features:

Z produced by our factoryHTAutomatic constant temperature electric heating sleeveUsing high-quality heat-resistant glass fiber as insulation material, the electric heating element is enclosed and wrapped in an insulation layer. The heater is equipped with insulation material, which has a high utilization rate of heat and can usually save electricity35%Above. Therefore, it has the advantages of energy saving, lightweight, safety, uniform heating, high efficiency, no open flame, and not easy to damage glass instruments. It can be used with various flasks, beakers, conical flasks, and is suitable for heating and insulation of various liquids in laboratories, analysis rooms, and laboratories of scientific research, chemical engineering, oil fields, medicine, colleges and mining units. It is an ideal practical heating equipment.

2、 Technical performance:

Voltage used: 220V５０ ＨＺ

Surface temperature:200℃－350℃

Working hours: 4-8 hours during high temperatures. Work continuously for 24 hours at low temperatures.

3、 Model number

1TheDMInternal heating fiberglass heater (direct heating type)

The structure is simple, easy to use, and can work simply by plugging in the power supply.

2TheKDMContinuous adjustable temperature heater (pressure regulating)

atDMOn the basis of the model, a voltage regulating circuit has been added, which plays a role in temperature regulation by changing the voltage, enhancing practicality.

3TheZHTType automatic constant temperature heater (pressure regulating constant temperature type)

This model isKDMOn the basis of type,Added constant temperature circuit,When used in conjunction with an electric contact mercury thermometer, the purpose of constant temperature can be achieved. Its advantage is that when connected to an electric contact thermometer (self equipped), it can maintain a constant temperature, and when removed, it automatically becomes a continuously adjustable voltage temperature controller, making it more versatile.

4TheSHTType digital display constant temperature electric heating sleeve

This model is inKDMOn the basis of the model, a digital temperature controller has been added to enable direct temperature display, automatic temperature control, intelligence, accuracy, and higher precision.

4、 Usage:

（Ⅰ）Observe the entire machine panel to understand the functions of each switch terminal. Connect the temperature sensing probe, turn on the power switch,Connect the power plug to the power supply and gently rotate the voltage adjustment knob to see the voltage change. To achieve the purpose of temperature regulation, when used in conjunction with digital temperature control instruments, the temperature control accuracy can be improved. More convenient and flexible to use.

(II) Digital display constant temperature

1 Observe the entire machine panel to understand the functions of each switch, terminal, and knob.

2 Adjust the digital display in the instrument panel to the desired temperature value. （0—399℃）

3 Connect the sensor to the two terminals behind the instrument panel, and do not connect them in reverse, otherwise the digital temperature of the digital device will decrease. And install the sensor in a position that can accurately reflect the temperature measurement required.

4 The switch is in the on position.

5 The setting of the temperature control instrument: the upper window is the measurement value display unit, and the lower window is the set value display unit. When using, it is necessary to first set the required temperature and then control it automatically. The left button below the instrument panel is the setting button, the second button is the shift button, the third button is the decrease button, and the fourth button is the increase button. The setting method is to press the setting button once to enter the setting state, then press other buttons to reach the desired temperature, complete the setting, and finally press the setting button to save and exit. The instrument enters the working state.

6 Self tuning: Sometimes, due to different heating conditions, the constant temperature error may be large, so tuning is necessary. The method is to measure the temperature value of the instrument at the set temperature(The set temperature value should be consistent with the temperature during use)When pressing and holding the shift button for five seconds, the instrument will enter a self-tuning state. Wait for the instrument to proceed1.5The setting process will automatically end after the return trip,The self-tuning process may take a long time,Half an hour or even several hours,Related to the process of heating up and cooling down during heating.Automatically save the obtained data,The next time it is used, it will run according to the data set this time.

7 Please carefully read the instrument and instrument manual. The instrument may not have ideal temperature control at the beginning, but it will automatically adjust to achieve better accuracy later. If repeatedly applied, there may still be significant errors,Just adjust according to the method introduced in the previous article.

5、 Attention:

It is normal to emit white smoke during the first use, and it can be used normally after there is no smoke.

After being damp, sometimes induced electricity is generated. Do not touch it with your hands and wait for heating1－2Normal in minutes.

The knob can only rotate270°Do not exert too much force, which may cause damage.

When the temperature is not adjusted,[Adjustable - direct heating]The switch in the direct heating position is equivalent to a direct heating type, which can extend the lifespan of its temperature control circuit. The digital display instrument does not work at this position.
