Anton Paar's DMA 35 EX Petrol Portable Density Meter is used for measuring petroleum samples in hazardous environments. One portable density meter replaces all the glass hydrometers in the workplace with the same accuracy expected from a lab instrument. The DMA 35 series uses only two milliliters of sample and saves the user time as there is no need to transport the sample to the lab. It is built to withstand the knocks and spills of outdoor use. An RFID interface for quick sample identification and a Bluetooth® interface for convenient data handling in the field are integral parts of the instrument.
