GB/T 2912.1 textiles determination of formaldehyde - part 1: free and hydrolyzed
ISO 14184-1, JIS L1041
1, Using the extraction method, the determination value of formaldehyde, absorbance value and transmittance of formaldehyde can be measured at the same time according to the national standard method.
2, MCU control, automatic spectral data processing, Chinese and English liquid crystal display.
3, Adopt the principle of electrochemical sensor and single-chip microcomputer technology to collect the absorbance value of continuous concentration of different points, and calculate the formula of the curve automatically according to the absorbance value corresponding to different concentration.
4, The design of the self quasi optical path is selected with the selected wavelength and wide range of the test wavelength.
5, The host can make 7 samples standard absorption curve function; the curve calculation uses discrete computing method, directly displaying a and b value (standard curve y=a+bx), without manual calculation.
6, With the computer online data transmission, print data reports.
