Features
1) Automatic control function;
Self-test of the working status of the internal system of the instrument when it is turned on;
Automatic calibration of color filters;
Automatic switching of light sources;
Display all kinds of error messages;
Data and graph storage and printing.
2) Analyze the test function
Photometry: Measure the absorbance or transmittance of a sample;
Quantitative analysis: A standard curve is established using a standard sample, and the concentration of an unknown sample is measured using this curve, and if the slope and intercept of the curve are known, the coefficient method can also be used.
