TWJR-B

product features

1.Exclusively adopt the square TU2 red copper plate which is processed by vacuum coating to heat ,with beautiful appearance and anticorrosion ,without deformation when get heated.

2.Special heating mode (applied for patent ),the surface maximum temperature can be up to 350°C.

3.Electric voltage adjustment circuit is equipped inside , controlled silicon controlling .

4.Can heat the standard and off-standard 50-1000ml reaction –bulbs and other canisters which contains no magnetic metal.

5.The shell adopts one-time forming flame retardant strengthen PBT injection molding shell, with thermostability,anti-corrosion and good insulation property.

6.30 ° cant control panel is suitable for standing and sitting viewing angle.

Usage

1.Fix the lever in the screw hole at the back and above of the instrument(attention :clockwise and counterclockwise ),adjust the hight of the cross clip and fasten the reaction bulb with the universal clip ,then put into a appropriate stirring pebble.Connect to the AV 220v power source and open the power switch.

2.Adjust the “temperature adjustment”knob clockwisely , make it at a right place according to the needed temperature to carry out heating.

3.If needed to display the temperature,a glass thermometer or a digital thermometer can be used as auxiliary measurement.

Attention

1.temperature of heating plate is high ,watch out when operating to avoid scald .

2.please don't use the instrument without any load.

3..instrument should be earthed well .(instrument should has a good earthing )

4.. At first usage ,it is normal when some white smoke and peculiar smell escapes from the instrument ,because the inner insulation material is made with some oil and other compound. At this time ,you just should put it in the tip-off place .you can use it after a few minutes smoke will disappear .

5..There will be inductive electricity passing through the thermal insulation layer and transmit to the shell when the instrument is placed in a humid environment or some liquid run over . so ,earthing is necessary and pay attention to tip-off. If electricity leaking is very serious , plz don’t use it .in order to avoid any danger, put it under the sun or dry it in a oven .

6..In case of power off , please check the fuse first at the back and above and see to it that whether it gets changed.

7..Long time no use ,please keep it clean and reserve it in a dry and without any corrosion air place .

When there is some change and difference about the specification which is caused by products or products reform related to the specification , pardon that we won’t inform you.
