Hioki MR8990 DIGITAL VOLTMETER UNIT
High resolution of 6.5-digit and 1,200,000 counts for minute voltage measuring
- DVM unit dedicated to DCV measurement
- Isolated 2 channel input
- Max. rated voltage to ground: 300 V AC or DC (CAT II)
- High-precision measurement for applications such as investigating minute voltage fluctuations in sensor output
- Unlike standard multi-channel scanning-type loggers, this instrument can perform simultaneous sampling
- High accuracy of ±0.01 % and super-high 1.2 million-count resolution
- High-speed sampling at 500 S/s
