C-600 from TFtestkits

[Rodex]

I ran across this C-600. Right now I use a pretty good pH meter but it’s precision overkill and a little unfriendly for my kids to use.

I searched here for any threads on this model but didn’t find any. Has anyone used this?

Maybe @Sarah and Nate can tell us more about it and why they chose to carry it.

Glad you asked. This meter definitely has a lot of features that are not immediately useful for TFPC (conductivity, specific gravity, etc.), but there are two invaluable features:
1. From my initial impressions, it offers very accurate and repeatable pH testing. Even though this level of accuracy is not required, it can be useful as it minimizes the amount of error in your readings. Calibration seemed pretty easy when I performed it as well.
2. It also offers very accurate and repeatable salt testing. Out of the box I was getting salt readings that were within 30 ppm of dropper testing with R-0718. Since the salt reagents cost almost $30 already, if this meter remains useful for a year plus it's certainly comparable to the dropper based test.
I don't want to mislead anyone here - I have carried these meters for around a month now so it's really too soon to tell of their long-term success. I am always happy to answer further questions via email at [email protected].

Thanks, even if this gave me a rough idea, it seems worth it to be a more frequently used type of tester. I’ll let you know if I have problems with it.

Got this in today, thanks. pH is within 0.1 of my fancy tester. Temperature was 1.5degF low, but my tester actually also seems to be off. Using a calibrated Thermapen, it might be closer to 4degF low.

The salt ppm reads 3800 but my dropper tests at 3200. It probably just needs to be calibrated, so I’ll look into that.

The pH measurement precision is pretty wide. Just from using it a few times, turning it off and on again, I’d put it close to +/-0.5.
