The Yocto-milliVolt-Rx-BNC device is a high precision USB voltmeter. It will let you measure by USB very small voltages (down to a few dozens of microVolts, and up to 2V max), even when they are generated by extremely weak sources (very high impedance). The BNC connector makes it possible to bring the signal using a shielded coaxial cable. 

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 less sensitive signals, you can use the variant of this product that has a rising cage connector, and which is significantly shorter.

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.
