Comprehensive test and measurement service provider-Shenzhen Weike Electronic Technology Co.
● Newly released 24bit high-resolution digital voltmeter unit MR8990! High-speed, high-precision measurements can be realized without a scanner.
:: Suitable for multi-channel testing (MR8740: 54ch, MR8741: 16ch)
● Insulated input (insulation between each input channel and between enclosures: maximum rated voltage to ground AC, DC 300V)
:: High-speed sampling (maximum 20 MS/s, maximum 32 ch simultaneous sampling for 54 ch models)
● Suitable for assembly in a rack (within 4U-180mm high, no display, rectangular)
:: Remote measurement via LAN communication (data transfer to memory, computer operation at a location far from the measurement site)
