Type: LST-219
The digital colorimeter is designed to measure the light transmittance of solutions, as well as the reaction rate of those chemical reactions that have a color or transparency change during the reaction. The digital colorimeter is used to carry out typical experiments: fading reaction of potassium permanganate solution and oxalic acid solution; determination of substance concentration in solution (Beer’s Law); reaction of sodium thiosulfate with concentrated sulfuric acid. The sensor meets the following parameters:
1. Spectral range: 4 wave lengths located in the 400 nm ~ 650 nm range, i.e.: the wave length of red light is 635nm, orange light 605nm, green light 545nm and blue light 470nm.
2. Colorimetric absorbance: 0 ~ 3 u.a.
3. Transmission: 20 ~90% (enhanced range up to 0 ~ 100%).
The sensor is compatible with data loggers, connection via RJ45 interface.
