2.4 optional measurement functions, including optical rotation, specific rotation, concentration and international sugar content.
3. Long-life LEDs are equipped with 589nm filters to avoid the 200-hour lifespan limit of traditional Illuminants.
4. Built-in temperature sensor, real-time sensing of temperature changes in the sample chamber.
5. Touch button design, just press the < or > key to start the measurement process.
6. Automatic zero system, one key recovery Optical inspection zero point.
7. Automatic temperature compensation, instant conversion Measured value to 20 ° C specific curl value.
8. Optional testtube length (100, 200mm or custom), automatically calculate the Measured value of non-standard testtube.
9. Manual zero correction, can adjust Optical inspection field of view and delete zero error.
10.1 to 3 point calibrated to ensure measurement accuracy over the full range.
11. Automatic information prompts to help users understand the current steps that can be performed.
12.100 sets of data storage, automatically marking the time, date and input the sample name.
13. USB Communication interface can send stored data to PC.
14. Built-in text file detailing the use of the instrument.
15. One-click reset function (Reset) automatically restores the instrument to the factory state.
Principle
The POL-200 Polarimeter uses LED Illuminant with 589nm Interference filter to determine optical rotation, specific rotation, concentration and sugar content by measuring the swirl/spin angle of Optical rotation compound solution to polarized light. Built-in temperature sensor monitors sample temperature in real time, and with automatic temperature compensation function, the Measured value is instantly converted to the specific rotation value at 20 ° C standard conditions to ensure measurement accuracy.
Applications
Optical rotation compound solution measurement, sugar content analysis, concentration determination, specific rotation detection
Standards
International Sugar Standard (ISS)
Steps
1. Turn on the power of the instrument and enter the system menu to set the function parameters.
2. Select Measurement mode (optical rotation, specific rotation, concentration or sugar content).
3. Select or customize the testtube length.
4. Press the < or > key to start the measurement process.
5. The instrument automatically returns to zero and temperature compensation.
6. Read the measurement results and perform zero correction manually.
7. Data is automatically stored or sent to the computer via the USB interface.
Notice
• Make sure the instrument is accurately calibrated before use.
• Avoid operating in extreme temperature environments.
• Regularly check Illuminant and filter status.
• Data must be exported in time after 100 sets are stored.
• The reset function will be restored to factory settings, so use it with caution.
