📏 Enhanced Precision: Extra Large Buffer Calibration Kit - The Ultimate Tool for Accurate Measurements Review

I ordered this machine to improve my dry sausage making skills. Most recipes I've found give you a few hours to ferment carefully to check pH and tweak flavor. I was looking for a quality portable tester and this is the right tool to provide accurate and reproducible results. The device can be calibrated and video tutorials answer many questions.

I bought these to test the Dr.Meter PH002. A pH 7 buffer solution is essential to zero the flow meter. Using distilled water from the grocery store, the meter read a pH of 5.9, likely because distilled water normally absorbs CO2 from the air and can be quite acidic. You need a pH-buffered solution with a neutral pH to ensure your solution is truly neutral. The other two solutions will let you know if the scaling factor is correct (which you can't adjust on this gauge). The kit comes with MSDS…

. After using them for a few months, I noticed something was wrong. It's wine season and my neighbor's pH levels didn't match mine. I dug up some old expired buffers (Orion brand) to measure after calibrating my electrode/meter with the buffers in this kit. Guess what?! 7 wasn't 7 and 4 wasn't 4. Double checked with two other buffer sets (Baker and Milwaukee) and indeed they matched my old expired set! Recalibrating with the old buffers and 7 and 4 from this set showed 7.25 and 4.33…
