Salinity Probe Calibration
Salinity is a measurement of dissolved solids in liquid: these solids will conduct electricity to varying degrees. A special probe is used, with two electrical contacts in it, to determine the resistance to the flow of electricity in the liquid. The higher the resistance, the lower the PPM of dissolved solids.
In the MkII systems, the salinity probe is located in a port on the bottom of the pump module- manifold. This way we can look at the salinity level of the product water before deciding to either reject the water or accept it and divert it into the holding tank.
The salinity level in
The next step is to decide what medium to use as calibration solution. If a
The microprocessor calculates salinity from the signals sent back to it from the probe. The salinity circuit can be adjusted from the Spectra software by adjusting the “Salinity Calibra- tion” parameter, or from the display in the Salinity Cal window. Increase the calibration pa- rameter to increase the salinity reading.
Conductivity calibration solutions are available from Spectra Watermakers if another method of calibration is necessary. These solutions are
To remove the salinity probe, unplug the telephone style cable from the probe. Use a wrench to unscrew the probe from the manifold.
