Concentration Meter: DMA™ 4500 M Chemicals
With its new and patented U-tube core technology DMA™ 4500 M Chemicals is the density and concentration meter with the highest reliability, precision, and robustness available on the market. It stands out for a faster temperature regulation between 0 °C and 100 °C that saves you time, and a new viscosity correction that reduces the harmful influence of the sample’s viscosity by half – in the whole measuring range of 0 g/cm³ to 3 g/cm³ and 0 %w/w to 100 %w/w.
Due to the new condition monitoring and FillingCheck™, the DMA™ 4500 M Chemicals density and concentration meter also sets new standards in terms of intelligence and usability.
Additional outstanding features are small sample volume, fast results, fully automated data processing, over 140 built-in concentration tables, and maximum protection.Get in touch Document Finder
Over 140 calculation tables
It's concentrated - DMA™ 4500 M Chemicals comes with more than 140 built-in conversion tables covering salts, acids, alkalis, alcohols, sugar, and many more. Individual tables can be added any time.
Sample changer - automated. Data processing - automated. Results from up to 71 samples are provided automatically. Once the density measurements are done, the instrument processes the data into concentration results and sends it to you with an email notification.
DMA™ 4500 M Chemicals is made for aggressive chemicals. The density meter uses PCAP touchscreen technology with a chemically hardened glass surface. The measurement cell is made of glass and the filling adpaters made of Teflon. Maximum protection guaranteed.
The automated conversion of the density reading into a concentration value eliminates human error. There is no need to change the measuring setup even for the full concentration range. Safe operation and high quality results are the outcome.
Fast and easy
Lab personnel can handle the density meter after a minimum of training. The operator only needs 2 mL sample volume, no further consumables. The measurement itself only takes 30 seconds.
