The universally acclaimed four-ring method provides an exceptionally stable measurement over a wider range. These probes do not suffer polarisation, nor do they need frequent calibrations or cell changes.
The built-in temperature sensor allows automatically temperature compensated measurements and features easy operations and maintenance.
This conductivity probe is provided with a 4m cable incorporating colour coded wires for easy connection to the Hanna Instruments-8396 transmitters.
