Polarimeter POLAX-2L Polarimeter, which is known as an optical rotation meter, is an instrument to measure optical rotation of "optically active matter" such as saccharin, ascorbic acid and sodium glutamate. Model POLAX-2L Cat.No. 5223 Measurement Range Angle of rotation : -179.95° to +180.00° International sugar scale -130.0 °Z to +130.0 °Z Minimum Indication Angle of rotation 0.05° International sugar scale 0.1°Z Measurement Accuracy Angle of rotation ± 0.10° International sugar scale ±0.3°Z Measurement temperature range 5 to 40°C Light Source LED with interference filter ( 589nm ) Accessories Observation tubes : 100mm tube and 200mm tube / each Power Supply AC100 to 240V 50/60Hz Dimensions & Weight 43×21×29cm, 11.1kg (Main Unit only) Operation switches R ( + ) = Right rotation switch : Rotates the analyzer slowly to the right. L ( - ) = Left rotation switch : Rotates the analyzer slowly to the left. temp = Shift / Temp switch : Pressing this switch simultaneously with either ( + ) switch or the ( - ) switch will provide a faster rotation ( in the shift mode ). * When this switch is pressed for 2 seconds or more, the temperature of the sample chamber is indicated on the display panel (until the switch is released from pressing).
