Conductivity Transmitter to use with Four-ring Probe - HI8936

Na zalogi
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 transmitter to operate at peak performance at all times.
  • Automatic temperature compensation ensures fast, accurately compensated readings even during sudden temperature fluctuations.
  • Optional backlit, LCD display for easy viewing.

Easy Installation

The HI 8936 transmitter may be wall-mounted at any convenient location close to the measurement site. The HI8936 series should be used in conjunction with the HI7635 in-line probe or HI7638 platinum probe.


Automatic Temperature Compensation

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.


Optional LCD

HI8936”L” versions allow easy verification and monitoring of measured values and is easier to calibrate and maintain.


Direct Probe Connection

Direct connection of the probe to the transmitter assures a positive electrical connection with no signal loss over long distances.
