I. Introduction
Designing by European techniques, with its advance technology, stable
performance, novel structure and good using effect, this equipment is
widely used for in heating in labs of colleges, petrochemical
industries, medicine, and environment protection institutions etc.
Ⅱ. Characteristics
1. Cold
rolling sheet stretching and spraying exterior.
2. Use
advanced digital temperature control system can precisely control the
temperature of the heated liquid, easy to use, high precision,
temperature display intuitive.
3. Using
high quality nickel-chrome heating resistance wire sealed in high
temperature insulation layer. Woven into half the ball in heating sets,
with characteristics of large heating area, fast warm-up, high
temperature evenness, no open flame and so on.

Ⅴ. Operation instruction
a) Place
the equipment on level worktable,
put the sensor frame, and plug it into sensor block on the back of the
instruments
b) Fill
a liquid container in the instrument, and set the sensor in the heated
liquid.
c) Use
the same voltage as the machine required, and then the instrument’s
screen will display the temperature of the liquid.
d) Set
temperature: after press “S” ,the green button “Set” indicator light,
the screen display the set temperature, and press the arrow keys to
select the temperature you want to use. After setting temperature, press
“S” to display the actual temperature.
e) When
heated the red indicator light, lights off when not heated.
f) When
temperature rose to the set temperature at the first time, it may be
washed for few degrees; it will stabilize down when the temperature came
down.
g) Stirring
adjust: Adjust the stirring speed by turn the knob clockwise.
Ⅵ. Safety attentions
|
 Connect the device to an earthed power supply to ensure safety
of machine and experiment; connect the power as the machine
required. |
|
 This
equipment is forbid to use in inflammable and explosive,
poisonous and strong corrosive experiments. |
|
 Make
sure horizontal installation. |
|
 Non-professionals
are not allowed to disassemble and repair this machine. |
|
 Pay attention to the set temperature while dealing with the
inflammable matters. |
|
Make
sure dry the resin container, if the temperature is setting too
high by accident, the container would be dissolved and then fall
on the heater to cause fire. |
|
Overfilled
of sample will lead to overheat of working room under parts,
which will dissolve the inflammable
material and cause fire. |
|
 While
the machine is working, don’t touch the top, window and exhaust
port of the device to protect from high-temperature burns.pan> |
|
Read
the instruction book before operation. |
Ⅶ. Usage notes
1. Because
of the surface of heat insulation material is coated with grease, in the
first used shall first heat except when heating oil, will appear white
smoke, shut off the power after heating to smokeless, when the
temperature come down, it can normal use
2. When
use the instrument should pour the liquid into the container firstly,
and then put in the instrument to use.

Ⅸ. Storage and transportation
Keep it in dry and clean room with good ventilation and no corrosive
gas, prevent it from wetting by the rain and avoid violent collision in
transportation.
