Measure chemical concentration with this unit
Anton Paar
The DMA 4500 M chemicals meter (photo) measures concentration from the measured density, and has 140 built-in concentration tables covering salts, acids, alkalis, alcohols, sugar and more. Individual tables can be added at any time. The meter provides fully automated sample changing and data processing, and its touch screen technology uses chemically hardened glass for maximum protection. It requires a small sample volume (2 mL) and delivers fast results (30 s), and the automated conversion of the density reading into a concentration value elminates human error, says the manufacturer. — Anton Paar USA, Ashland, Va.
