Review on Apera Instruments AI1209 Replacement Conductivity by Draven Invert

Arrived safe and sound as promised. The instructions had to be read several times and manipulated with the device several times, then everything was very clear. Beautiful waterproof laminated score sheet to remind you which button to press when you want to do something. I particularly liked that when the EC of the water went above microsiemens, the units automatically switched to millisiemens. This caused some confusion at first (distilled water was higher than my salty well water) until I noticed the unit change. The print is really small for old eyes, but different mode labels are shown in different parts of the screen, so I've gotten used to admitting it. I think it will be exactly what I need and expect and will update the review after using it for more than a day.
