BK-P1 Series

Automatic Polarimeter


* LCD Display

* Photoelectric test and microcomputer control.

* Preheating is not needed. (Only for BK-P1 and BK-P2 Model)

* Dark-colored sample can be measure. (Only for BK-P1 and BK-P2 Model)

* Automatic repetition-measurement for 6 times, and calculation of average value and means square root

* Sample chamber adopts constant temperature designing in order to reduce the temperature heating influence.
