T-HRECS™

High resolution conductivity probes that reduce measurement uncertainty.

T-HRECS™ is a high resolution (14 bit) instrument for measuring Electrical Conductivity and Temperature. We developed this device to increase the Signal to Noise Ratio (SNR) of our salt dilution measurements, thereby lowering the measurement uncertainty or amount of salt required.  Devices are galvanically isolated, can operate independently on an external power supply, and can convert serial output to RS232, 4-20 mA, SDI-12, LoRa (>500m) or Zigbee Radio (over >100m).

Why is High Resolution important?  The higher information content of the signal results in a higher SNR.  This means that either less salt can be used in the measurement, or a lower uncertainty can be obtained.  The higher resolution device has higher information content, therefore higher SNR and lower uncertainty for the same tracer injections.  That is one of the reasons we built our own EC instrument.  Browse our recent presentations on the Derivation, Uncertainty, and Variance of the Calibration Factor used in Salt Dilution Flow Measurements and Quantifying and Controlling Error in Salt Dilution Flow Measurements.
