The Hioki DM7275-03 is a precision DC voltmeter, designed for demanding laboratories and production environments where the highest voltage accuracy is required. With a 7½-digit resolution and a measurement range from 100mV up to 1000V DC with an accuracy of ±0.0020% in the 10V range, this benchtop voltage meter is suitable for advanced applications such as battery cell testing, component verification, and long-term monitoring of minute voltage fluctuations. The high-contrast display with adjustable brightness ensures that the precise voltage readings remain clear and easy to read in any lighting condition. In addition, the DM7275-03 features advanced functions including a contact check function based on capacitance, temperature compensation (which needs the optional Z2001 temperature sensor), and extensive statistical analysis directly on the instrument. The self-calibration function and reference architecture ensure long-term stability and reliability. Unlike traditional multimeters, the DM7275-03 is specialised for high-accuracy DC voltage measurements and does not measure current or resistance.
The DM7275-03 is housed in a robust case suited for use in professional environments. The meter comes equipped with USB, LAN, and RS-232C interfaces. These interfaces allow for seamless integration into automated measurement setups or remote monitoring applications.
