At 2% caustic concentration you are right in the best range for conductivity measurement. Between 1 percent and 3 percent concentration, the conductivity will approximately triple from 50 to 150 ms/cm.
pH is best used for solutions less than 1 percent and density for solutions over 10 percent...
On a couple of occasions people have reported a green liquid coming from electrical fittings in houses. It is described as being bright fluorescent green.
Is anyone familiar with this phenomenon, and can you explain what causes it?
I agree with Stuart. Since there are often separate adsorption and desorption isotherms, it could be that you will end up with both processes happening concurrently and get a point in between.
Just for interest, I thought I'd try to put an illustration in here.
Thanks everyone for your helpful advice. Now I have some insight into inverters and three phase motors. The conveyor is a secondhand one, so no there is no warranty, but I was able to track down the motor supplier and get some useful input.
I run three small conveyors with 0.18 kW 3phase motors. Two of them run from single phase supplies through an inverter (0.75kW), providing variable speed. The new third conveyor runs on 3 phase directly.
I would like to run the new third conveyor from one of the inverters. I recall that it...
