Ordering Information All HI8936 models are supplied complete with instructions. AN, BN, CN, and DN without LCD ALN, BLN, CLN, and DLN with LCD HI8936 Series Conductivity Transmitters to use with Four-ring Probe • ATC · Automatic temperature compensation • Backlight · Backlit, LCD display HI8936 is a conductivity transmitter that utilizes a four-ring potentiometric probe. This probe is virtually immune to contamination by unclean solutions. This allows the transmitterto operate at peak performance at all times. Temperature effects are compensated for by utilizing both the built-in temperature sensor on the probe and the transmitter’s ATC circuitry with a � of 2%/°C. Direct connection of the probe to the transmitter assures a positive electrical connection with no signal loss over long distances. HI8936 ”L” versions allow easy verification and monitoring of measured values and is easier to calibrate and maintain. The HI8936 series requires external power to the 4-20 mA current loop. The HI8936 series should be used in conjunction with the HI7635 in-line probe or HI7638 platinum probe (see Process Electrodes and Probes).
