 The Hanna Instruments HI 7638 In-line conductivity probes combine the proven four-ring potentiometric method of measuring conductivity with platinum sensors. The universally acclaimed four-ring method provides an exceptionally stable measurement over a wider range. These probes do not suffer polarization, nor do they need frequent calibration or cell changes.

The built-in temperature sensor of the Hanna Instruments HI 7638 allows automatically temperature compensated measurements and features easy operation and maintenance.

HI 7638 and HI 7639 are provided with a 4 m cable incorporating color coded wires for easy connection to HI 8936 transmitters while HI 7640 provides a DIN connection.
