Hioki DM7275-03 Precision DC Voltmeter (20 PPM) with RS-232C Interface

Hioki DM7275-03 – Precision DC Voltmeter (20 PPM) with RS-232C Interface

High-Accuracy Measurement Approaching the Precision of Reference Instruments

The DM7276 Precision DC Voltmeter delivers superior measurement accuracy of 9 ppm (0.0009%), an accuracy level that is demanded by advanced applications such as aging tests of lithium-ion batteries. Other key features include contact check to maximize measurement reliability, binning and temperature compensation, making the voltmeter ideal for developing and manufacturing Li-ion batteries, electrical double-layer capacitors, electric vehicle components, and other next generation devices.

Advanced Applications

Precision for measuring a 4V battery at 48 μV accuracy + Increased efficiency using stable measurements with 1-year accuracy

For tests like OCV (Open Circuit Voltage) aging tests for batteries, where minute voltage changes are monitored over a long time to make a pass/fail judgment, the accuracy and long-term stability of the measuring instrument are essential. The DM7275 and DM7276 are unprecedented DC Voltmeters that ensure accuracy on the calibration device class for one year.

Transient Characteristics Monitor

DC Voltage Measurement Resistant to Noise + High-speed Sampling Mode Up to 1 msec × 5000 times

The high-speed sampling mode (measurement count setting function) can measure continuously up to 5000 times per trigger. You can also change the integration time from the fastest setting of 1 msec.

This makes it easy to acquire data for measurements which noise made difficult for waveform recording from a Hioki Memory HiCorder or oscilloscope, such as battery charge/discharge properties.
