Why am I getting faulty measurement results with my Kruss Measuring Instruments?
- P
  Phyllis PatelAug 3, 2025
  Faulty measurement results may occur due to several reasons: * The glass plates at the ends of the polarimeter tube might be dirty or stained. If so, clean the glass plates. * The polarimeter tube might be dirty. If so, clean the polarimeter tube. * There might be air bubbles in the optical path of the polarimeter tube. If so, fill in additional sample into the polarimeter tube. * The sample liquid might be extremely dark. If so, dilute the sample. * The saved blank was not measured with the current polarimeter tube. If so, measure the blank with the currently used polarimeter tube. * Calibration data is obsolete. If so, re-calibrate the measurement range. * Calibration data of the temperature sensor faulty. If so, re-calibrate the temperature sensor.

Why is the precision inferior on my kruss P3000?
- K
  Kelli GrimesAug 13, 2025
  Inferior precision may occur because the polarimeter was not cleaned thoroughly between sample measurements. Clean the polarimeter tube thoroughly after each measurement with distilled water or an appropriate solvent. Another reason might be that the sample has not yet reached room temperature. Wait until the sample has reached room temperature.
