Introduction
Thank you for selecting the POL-200 semiautomatic polarimeter. This user manual provides a step-by-step guide to help you operate the instrument, please
carefully read the following instructions before use.
UNPACKING THE INSTRUMENT:
Before unpacking, ensure that the current work environment meet following conditions.
●Ambient temperature is greater than 0oC and less than 50oC.
●No potential electromagnetic and ambient light interference.
The following list describes the standard accessories of the polarimeter. After the unpacking, please check all accessories are complete. If any are damaged
or missing, please contact nearest distributor.
●Test tube 100 and 200 mm
●Sealing rings
●Power cable
Power On/Off
●Plug in the power supply and press ON/OFF key to turn on the polarimeter, the display shows “Wait for light source to stabilize”. After a few seconds,
the default measurement interface shows on the screen.
●Press ON/OFF key again, the instrument will automatically turn off.
WARNING:
DO NOT pull out the power plug from the power source if the instrument does not completely turned off, that may cause the zero-point offset.
Display
POL-200 semiautomatic polarimeter is equipped with the 5.6 inch touch screen that used to show measured values, function keys and help message. In the
measurement and setting modes, the instrument will show different user interfaces.

Setup Menu
POL-200 semiautomatic polarimeter contains an integrated setup menu that allows you to customize each option to meet measurement requirements.
Selectable parameters contain the following options.
INDEX:
PARAMETER
OPTION
DESCRIPTION
Measurement Mode
●Optical Rotation
●Specific Rotation
●Concentration
●International Sugar Scale
Select your desired measurement mode.
Tube length
●100mm
●200mm
●Custom
During the custom mode, the instrument acceptable setting ranges
from 0.0 to 220.0mm.
Temperature Compensation
●Enable (Default)
●Disable
Temperature compensation allows the instrument to run at ambient
temperature but produces readings as if the system was running at
20ºC. During the Specific Rotation, Concentration and Sugar Degrees
modes, the instrument will automatically enable the this feature.
Concentration
---
Sets the concentration of sample for measurement of specific rotation
Specific Rotation
---
Sets the specific rotation of sample for measurement of concentration
Temperature Setting
Range: 0.0 to 100.0oC

Measurement
POL-200 semiautomatic polarimeter can be used for measuring the four parameters, including the optical rotation, specific rotation, concentration and
International Sugar Scale. Click the Setup icon to enter the setup menu, then click the “Measurement Mode”icon to select desired measurement mode.
When the setting is completed, the instrument will automatically return to selected measurement mode.
1. Take out the tube from the sample chamber. Unscrew the cap, remove the sealing ring and glass disc.
2. Pour sample solution into the tube, screw on the tube cap. Wipe away the drops of water on glass disc.
3. If necessary collect all air bubbles into the bubble trap.
4. Place tube into the sample chamber. The bubble trap is upward.
5. Press or key until visual field appears uniform brightness. Record the measured value.
6. Press Return key, the instrument returns to the zero-point automatically. Measurement is completed.
Press and hold or key for 8 seconds, the instrument will enter auto-run mode. Press or key again, the instrument stops running.
