Phidgets 20-Bit (±40V) high precision isolated voltage input, resolution 77 microvolts, 13mA

Measure up to ±40V with this high precision isolated voltage input Phidget. Connects to a VINT port.

You have to measure larger voltage potentials, but would you also like to make highly precise measurements? This Phidget voltage input is the best of both worlds. With this impressive little Phidget you can measure voltages up to ±40V with a resolution of 77 microvolts. You can switch the voltage range via software to ±312mV mode.

Isolates for stability />
This Phidget is electrically isolated so that a surge in the circuit you are measuring will not damage your VINT hub or your computer. Isolation also improves stability by eliminating potential ground loops.
