Wireless Conductivity Sensor

Wireless Conductivity Sensor

This waterproof sensor connects via Bluetooth® to measure both conductivity (ionic content in solution) and total dissolved solids.

Many lab activities can be conducted with our Wireless, PASPORT, or even ScienceWorkshop sensors and equipment. For assistance with substituting compatible instruments, contact PASCO Technical Support. We're here to help.
