HI8931 EC Analog Controller with Input from Probe or Transmitter
Previous | 27 / 31 | Next |
RM 2,941.00
- Available in four models with different measurement ranges.
- Temperature compensation ensures fast, accurately compensated readings even during sudden temperature fluctuations.
- Backlit, LCD display for easy viewing.
Measurement Specific Models
- Four different models are available with different measurement ranges, each one to be used with the corresponding HI 8936 model.
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’).
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.
Direct Connection
- HI8931 also features a direct connection up to 20 m (67’), without needing to amplify the signal to the conductivity probe.
Automatic Temperature Compensation
- Built-in temperature sensor in recommended probes ensure fast, accurately compensated readings even during sudden temperature fluctuations.
Robust Design
- A removable, transparent splash-proof cover protects the front panel.
