Ok. my turn
There are Alk monitors @ $ 8,000 by HACH, APA 6000. There is also a Ca monitor, another 8 grand
. Both monitor a sample stream and perform titrations of that stream. They run for 1 month then you have to refill the reagent bottles.

Can the monitor run submersed 24/7 or is it only for intermittant testing
This bothers me also. I wound wonder about abiotic precip on the probe.
