Semi-automatic polarimeterTechnical Analysis and Application Guide:

　　Semi-automatic polarimeterIt is a precision instrument used to determine the optical rotation of substances. Its core function is to measure the rotation angle (optical rotation) of the vibrating surface after plane polarized light passes through the optically active substance, and calculate parameters such as specific rotation, concentration, purity, and sugar content of the substance.

Key technical features:

Light source and lifespan:

LED light source: With a lifespan of over 100000 hours, it replaces traditional sodium lamps and reduces maintenance costs.

Wavelength stability: The 589nm wavelength ensures measurement consistency.

Measurement accuracy and range:

Typical measurement range: ± 90 ° (optical rotation), ± 130 ° Z (international sugar content).

The accuracy can reach ± 0.02 ° and the resolution is 0.005 °, meeting the high-precision requirements.

Calibration and compensation functions:

1-3 point calibration: covering the full range and eliminating system errors.

Manual zero correction: Correct zero deviation by adjusting the optical field of view.

Temperature compensation: The built-in sensor automatically corrects the effect of temperature on optical rotation (for every 1 ℃ increase in temperature, the optical rotation decreases by about 0.3%).

Data Management and Operations:

Touch screen interface: The 5.6-inch TFT screen supports parameter settings and data input.

Storage and output: can store up to 100 sets of data, supports USB interface export to computer.

One click reset: Quickly restore factory settings and simplify the operation process.

Application fields:
