Simultaneously measure up to 32 channels at high resolution

The MR6000 can simultaneously measure up to 32 channels, while the MR8740T can measure up to 108 channels at a time. Thanks to four input channels and a high-sensitivity 100 mV f.s. range, the U8978 can measure multiple channels of signals from a variety of sensors. The unit is ideal for use in measuring currents of various magnitudes in the development of automobile accessory controls. Utilized in combination with the multi-range Current Probe CT6711, it can measure currents from 1 mA to 50 A.
