    WQ-ORP Smart USB Sensor Troubleshooting

    The slope and response characteristics of the ORP sensor can be tested in quinhydrone-saturated pH 4 and 7 solution.  A properly functioning ORP electrode should exhibit a difference of 90 ± 40 mV when submersed in the two solutions of quinhydrone-saturated pH 4 and pH 7 solutions. Prepare two beakers, one with pH 4 solution […]

    Oxidation Reduction Potential Overview

    Oxidation-Reduction Potential (ORP) provides an indication of a solution’s ability to oxidize or reduce another material. ORP is often also called “Redox”.  ORP is a useful water quality parameter, particularly for processes such as water disinfection, odor control processes, and dechlorination processes prior to industrial or municipal discharge. Oxidation and Reduction Reviewed Oxidation is the […]

    Calibrating WQ-ORP Smart USB Sensor

    The WQ-ORP sensor is calibrated with a 1-point calibration in a standard solution with a known ORP, such as Zobell solution, Light’s solution, or quinhydrone-saturated pH buffers. The following table can be used when calibrating with Zobell solution, the NexSens-recommended standard. Temperature in °C Zobell Solution in millivolts -5 270.0 0 263.5 5 257.0 10 […]
