Colorimeter logger sensor NUL-219

Colorimeter logger sensor


The colorimeter measures transmittance and absorbance of red, orange, green and blue light components projected on a solution.

The colorimeter logger sensor has an opening for a special square solution cuvette. It turns on four different lights in known values and measures the received light that passes through the solution.

This sensor has two modes of operation: Absorbance and Transmitence. Note: The plastic tube (cuvette) must be put in a certain way inside the colorimeter. The cuvette has two rough sides. These sides should not be in the line of the light. Three cuvettes are supplied with the sensor.
