What you need to pay attention to when using electric heating sleeves

Electric heating sleeve is a kind of laboratory general heating instrument, which is composed of a hemispherical heating inner sleeve and a control circuit woven of alkali-free glass fiber and metal heating wire, and is mostly used for temperature control heating
of glass containers.

With the characteristics of fast heating, high temperature, simple operation and durability, it is an ideal instrument for temperature control heating test.
Function classification: 1.
Electronic temperature regulation electric heating sleeve: voltmeter regulation temperature 2.
Constant temperature digital display electric heating sleeve: digital display meter regulation and display temperature 3.
Digital display stirring electric heating sleeve: digital display meter adjustment and display temperature, and with stirring function 4.
Temperature regulation stirring electric heating sleeve: Voltmeter regulates temperature, and with stirring function 5.
Microcomputer electric heating sleeve: The control circuit adopts microcomputer control
.

Precautions 1.
The instrument should have good grounding
.

2.
When using, there is white smoke and odor in the sleeve, and the color changes from white to brown and then to white, because the glass fiber contains oil and other compounds in the production process, which should be placed in the ventilation place, and can be used
normally after disappearing in a few minutes.

3.
3000ml or more of the electric heating sleeve when using the squeak - squeak sound is different from the wire structure and related to the thyristor voltage regulation pulse signal, can be used
with confidence.

4.
When the liquid overflows into the sleeve, please quickly turn off the power supply, put the electric heating sleeve in a ventilated place, and use it after drying, so as to avoid leakage or short circuit of
the electrical appliance.

5.
When not used for a long time, please put the electric heating sleeve in a dry and corrosive-free gas for preservation
.

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

7.
When the ambient humidity is relatively large, there may be induction electricity transmitted to the shell through the insulation layer, please pay attention to the grounding wire and pay attention to ventilation
.
