Review on AUNMAS Portable Function Salinity Temperature by Robert Ryokan
DO NOT BUY THIS! DOESN'T CALIBRATE PH CORRECTLY!
This thing is pure junk. Solution 9.18 is not calibrated. Now 6.86, then 4.0. Not 9.18. This renders this product unusable. I figured I'd spend $50 on a good water tester. But that's a waste. Buy quality from somewhere with a good reputation. Lesson learned.
- IP67, this gauge can still be used when it enters the fish tank, convenient to use.
- Only available in white
