Short Communications: Short technical description of the MonA and PotLab colorimeters
The MonA and PotLab instruments represent the upper and lower limits of a range of rugged colorimeters designed for use in developing countries based on the concept of using a light emitting diode (LED) as an alternative to the tungsten lamp and filter of the conventional colorimeter. The green LED with a maximum emission around 565 nm and a band-width of 30 nm was chosen because it is the only...

The effect of non-linearity of the calibration scale is minimised by its generous length, over 255 mm, and the expansion of the scale divisions in the more critical lower range. Zero adjustment is by mechanical microadjustment which moves the reference cell from the side of the LED.
