The HI 8614N is a water-resistant pH transmitter is designed to be used with a standard high impedance pH probe with BNC connector.

Conductivity Process Controller & Transmitter type HI 8936 uses a four-ring potentiometric probe- is virtually immune to contamination by unclean solutions. Moreover, the compensated, in the probe, simplified integrated temperature sensor and provides automatic Temperature compensation probe is connected to a positive electrical connection to signal loss to avoid long lines and to increase the performance of the controller.
