Any Videos or Detailed Testing info on C-600 PH meter

The meter is said to be factory calibrated so the solutions shouldn’t be necessary unless recalibration is needed.

They all say that but I cant believe they employ someone to individually calibrate each meter with a quality standard. In reality the meters are preprogrammed to something close to the most common use which would be tap water, 1413mS/cm. Or maybe a 442 value. The farther you get away from the calibration point the more chance of error.

My last meter, a Kedida, was meant to be factory calibrated to 12.88mS/cm from new but it was about 600ppm out.

Thing is I went through the booklet, saw this calibration section, thought I had to do it. So I went ahead and did the operations described in that "1413" line in the screenshot without actually put the meter into any liquid. Did I “uncalibrate” it?

Can you link me to posts where users are not having luck with the C-600?

I have been running this meter alongside of the drop test for at least a month now just to test it daily. It is super accurate every time

Not sure you can really discern “super accuracy” using a comparator drop test. You can however purchase buffer solutions of a known, precise pH as a comparison. I bought one with a pH of 8.2 which is in my area of interest.

Yes, you have most likely uncalibrated it. It will now think that what ever fluid you had it in is now 1413. If it was dry it will think something close to zero is 1413. Follow the instructions to re set it to the factory settings.

I would guess yes. It’s my understanding that you would only have to recalibrate at one point after reset, and 12.88 mS/cm would be my recommendation since it is closest to our usual ~3500 ppm of salt. Reach out to me via email and we can discuss how I can make this right for you.
