In-line Conductivity Probes with Platinum Ring
These 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. HI7638 and HI7639’s built-in temperature sensor allows automatically temperature compensated measurements and features easy operation and maintenance.
