Antique and very early portable colorimeter made by Hellige & Co. In Germany during beginning of XX century. Lab device used in chemical and medical industry with a prisma and screen to see spectrum.This unusual colorimeter is really hard to find, and you can only see this model at the Science Museum Group (but in poor condition and missing parts, not like this one, incredibly well preserved and complete). A museum piece really hard to find for demanding collectors. Height is 18 centimeters, wide is 7 cetimeters and depth is almost 6 centimeters. If you have any question, do not hesitate to contact me.
