RXMVOLT1 Yocto MilliVolt Rx Voltmeter

The Swiss-made high-precision RXMVOLT1 Yocto MilliVolt Rx Voltmeter will let you measure very small voltages (down to a few dozen of microVolts, and up to 2V max) via a USB, even when they are generated by extremely weak sources (very high impedance).

Typical applications include measurement of electro-chemical reactions (e.g. pH and redox probes), low-voltage sensors (e.g. gaz sensors, etc) or Wheatstone bridges (e.g. load cells, etc). It is also possible to use this device to precisely measure the voltage drop accross a shunt to measure high currents.

The input circuit of this device uses a very low bias current amplifier (typ. 0.2 pA). The measure circuit is electrically isolated from the USB bus, which makes it possible to measure grounded voltages without risk of creating a ground loop.

For measuring the weakest signals (e.g. pH measurements), it is recommanded to use the BNC variant of this product, which features a BNC connector to use with coaxial cable, and avoid electromagnetic interferences.
