Absorption detection system
Product Introduction
Absorbance is a physical quantity used to measure the degree of absorption of light. The absorbance detector is suitable for measuring the absorbance of solutions. There are three measurement schemes for this detector:
-
- Measure using a four-way colorimetric dish
- Measurement using a variable optical path colorimetric dish
- Measurement using an immersion probe
The system can flexibly select configurations according to different application scenarios to meet diverse detection needs.

Absorbance testing software
This software can display real-time absorbance data corresponding to each wavelength. Users can customize measurement schemes and set parameters such as upper and lower limits, average absorbance, etc. for any wavelength for automatic judgment, making quality inspection more convenient and efficient.
In addition, the software can also test the transmittance and reflectance of samples, and calculate CIE color parameters (such as XY/LAB), dominant wavelength, saturation, color purity, and other parameters, with powerful and flexible functions. The software supports user customization functions to meet personalized application needs.
