The Yocto-milliVolt-Rx device is a high precision USB voltmeter. It will let you measure by USB very small voltages (down to a few dozen of microVolts, and up to 2V max), 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.

This device can be connected directly to an Ethernet network using a YoctoHub-Ethernet, to a WiFi network using a YoctoHub-Wireless-g, it can even be connected to a GSM network thanks to the YoctoHub-GSM.

USB cables and enclosure to be ordered separately.
