Measurement Specific Models Four different models are available with different measurement ranges, each one to be used with the corresponding HI 8936 model. In-line and Tank Use For in-line applications, use the HI7635 probe, while for tanks the HI7638 with external threads is recommended. These probes are provided with a built-in NTC sensor for temperature compensated conductivity measurements. Automatic Temperature Compensation Built-in temperature sensor in recommended probes ensure fast, accurately compensated readings even during sudden temperature fluctuations. Use With Transmitter Using the HI8931 in conjunction with a 4-20 mA output transmitter (HI8936 or HI8936L series) will assure a strong, interference free signal at distances up to 300 meters (1000'). Direct Connection HI8931 also features a direct connection up to 20 m (67'), without needing to amplify the signal to the conductivity probe. Robust Design A removable, transparent splash-proof cover protects the front panel.
