"The Anton-Paar DMA-35 is a handheld, stand-alone digital density meter suitable for use in demanding industrial environments.","Measuring specific gravity and electrolyte temperature has always been a time consuming, messy chore requiring two technicians: one to take the readings, the other to write down the data. Now, one technician can both measure specific gravity and temperature and record the data more quickly than with other conventional methods.","Simply press a lever and, within seconds, the temperature, density, specific gravity, or percent concentration of the sample is displayed. To save the data, press a button; up to 1,024 data points may be stored in the instrument.","Weighing in at 10 ounces, the DMA-35 digital hydrometer won’t tire you out, no matter how many samples you must measure. And the DMA-35 delivers up to 90 hours of service on two alkaline 1.5 volt AAA batteries."
