Water Quality Measurement Probes

[flanque]

Hi all,

I've been curious about this for a while and finally asked the chemist at work about it.. You CAN get probes that will measure various water qualities and they are arguably affordable.

Some even have RS-232 outputs for data logging.

There's more if you search google for "calcium sensor probe".


Enjoy!

Usually the really expensive part is the controller. The probe is usually some sort of bi-metal job with a current supplied or generated. If you can convert raw probe data to an RS-232 signal, that would be very cool.
