Description
Visible Spectrophotometer
A Portable visible spectrophotometer is small in appearance and powerful in function. It adopts 5-inch true color touch screen and has humanized design, which makes the operation easier and meets the needs of different customers. It is widely used in teaching and daily analysis
Luminosity measurement
Test the absorbance, transmittance, and energy of the sample at a certain wavelength.
Quantitative test
Establish a standard curve for the concentration test (A4L).
