Description
DM7275 Precision DC Voltmeter for R&D and Production
The DM7275 Precision DC Voltmeter is designed for high-accuracy DC voltage measurements required in advanced applications such as lithium-ion battery aging tests, electric vehicle component testing, and next-generation electronic devices. With a 7½-digit resolution and a 20 ppm (0.002%) guaranteed accuracy over one year, the DM7275 ensures reliable and repeatable results for both laboratory and production environments.
Equipped with a built-in capacitance contact check, the DM7275 maximizes measurement reliability, reducing errors caused by poor contact. Its temperature compensation function allows the display of voltage values converted to standard temperatures, a critical feature for components sensitive to minor ambient temperature fluctuations. This ensures accurate open-circuit voltage (OCV) readings even when environmental conditions vary by just 1°C (1.8°F).
The voltmeter is engineered with a highly stable internal voltage reference and fully automatic self-calibration, providing consistent long-term performance. Its measurement engine resists extreme temperature changes, guaranteeing high repeatability under challenging conditions.
Connectivity options include EXT I/O, LAN, USB, GP-IB, and RS-232C (model-dependent), making the DM7275 suitable for automated production lines or advanced research systems. The device supports global production with its variable built-in power supply, providing flexibility and compatibility for diverse applications.
Whether for R&D testing, quality control, or mass production monitoring, the DM7275 Precision DC Voltmeter combines high accuracy, advanced measurement functions, and user-friendly operation, making it a trusted choice for precision DC voltage testing.
