In-line Conductivity Probe with Platinum Ring, NTC Sensor and 3, 10 & 20 m Cable.
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.
The built-in temperature sensor for the HI 7638 allows automatically temperature compensated measurements and features easy operation and maintenance.
HI 7638 are provided with a choice of cable incorporating color coded wires for easy connection to HI 8936 transmitters.
