Take DMA 35 with you at all times and measure the density and concentration of your sample directly on-site – be it for intake control, at-line quality inspections, or on the road. The portable density meter uses only two milliliters of sample and saves you a lot of time as there is no need to transport the sample to the lab. DMA 35 is built to withstand the knocks and spills of outdoor use. If the measuring cell nevertheless suffers from cell rupture, you benefit from the unique patented connection of the measuring cell, which allows replacement. An RFID interface for quick sample identification and a Bluetooth® interface for convenient data handling in the field are integral parts of the instrument. To top it all off, DMA 35 can also be used as a mini benchtop instrument: Turn it upside down, put it on a table and fill the sample with a syringe.
