A revolutionary density measuring principle for the fastest concentration measurement       

The unique design of the measuring cell, a novel way of evaluating the oscillation characteristics, and many other innovative features lead to the following:       

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 at any time. Lab personnel can handle the concentration meter after a minimum of training. Only 2 mL of sample volume and no further consumables are required. The measurement itself only takes 30 seconds.        

Unaffected by harsh working conditions        DMA™ 4500 M Chemicals provides stable results under varying conditions, such as humidity, temperature, and air pressure. Its housing withstands shocks, dirt, and spillages. Even frequently changing users and filling styles do not influence the measurement results.        

Automatic bubble detection        Monitor your sample handling with the FillingCheck™ feature that helps you detect filling errors, gas bubbles, and particles in the sample. FillingCheck™ generates and records filling warnings and U-View™ documents the incident – it displays the image of the entire filled sample on the screen and stores it together with your result. Both features in combination supervise the entire measurement sequence and allow later verification of the results, which is particularly useful when you use automatic sampling systems.       

Maximum protection        DMA™ 4500 M Chemicals is made for aggressive chemicals such as concentrated acids or bases. The density meter uses PCAP touchscreen technology with a chemically hardened glass surface providing unmatched sensitivity and robustness at the same time. The measurement cell is made of glass and the filling adapters are made of Teflon. Maximum protection is guaranteed.       

Safe operation – fast and easy        The density reading is automatically converted into a concentration value and this eliminates human errors. There is no need to change the measuring setup, even for the full concentration range, so the instrument is immediately ready to go whatever concentration your sample has. Perform measurements manually or use a sample changer to handle higher sample throughput.
