Did you know that GIS carried hand refractometers?  Optical instruments which can quickly measure the concentration of aqueous solutions using the principle of the critical angle of refraction, and thus by a simple operation determine the refractive index of the liquid or material under test.  Every shop could use one, most shops need more than one!

If interested, please contact anyone in Customer Service with GIS, or send me an e-mail @ jmarquar@gisedminc.com

In addition to measuring the concentration, our ATAGO hand refractometers can also help correct the temperature of a measured sample!
