Review on 📐 Accurate Calibration with Milwaukee Instruments MC122US Controller by Robert Rick

First impressions are that this is a really great tool. It was clear how to set it up and it works as expected. The pH values were consistent with other devices and the switch to turn the devices on and off worked as expected. I use it to power the solenoid of my CO2 system in my aquarium. I love that the power management output is separate from the unit, so I can run a timer either on the unit or on a separate power plug (which means I can lock out the time the unit is reading pH levels measures, or can control the power supply separately). I've only had it for a day or so, but so far it seems like good value for money.
