I am looking for a electrical conductivity sensor which can be left submerged for continuous monitoring. Is the below sensor an industrial grade? if not please could you advise a sensor with a reasonable cost.
Gravity Analog Electrical Conductivity Meter
Product Code : RB-Dfr-663
Hello
The probe is a laboratory-grade probe. Do not immerse in liquid for a long time. Otherwise this will shorten the life of the probe.
Platinum black layer is attached to the surface of the sheet metal in the probe.It should avoid any object touching it. It can only be washed with distilled water, otherwise the platinum black layer will be damaged, resulting in inaccurate measurement.
Robotshop, unfortunately, do not carry an industrial-grade conductivity meter.
If you don’t need a lot of precision you could probably build your own for cheap and change it once it corrodes.
