VIVOSUN Digital PH Meter for Water, 0.01ph High Accuracy Pen Type PH Tester for Hydroponics, Household Drinking, Pool and Aquarium

VIVOSUN Digital PH Meter for Water, 0.01ph High Accuracy Pen Type PH Tester for Hydroponics, Household Drinking, Pool and Aquarium

Q: What do you use to clean electrode?

Instructions say to use distilled water to clean electrodes

Q: Would this be a good tool for an aquarium?

Sure it will read the Ph for your tank

Q: Does it work well for testing ph in a saltwater pool?

I don’t know anything about testing pool water but it will definitely give you the ph between 4.0-10

Q: My pen has gone way out of calibration. Is there a way to calibrate it against an accurate test kit? I.e. just set the pH?

I second the answer but Alix. I thought it could be recalibrated against the standards they provide and I would be back to using the ph tool. Once it started to give me bogus readings I knew I had a new paper weight. I even bought 7.0 fluid so I could check it before each use so I knew the readings were correct. I have extensive experience calibrating thousands of gauges in a railroad machine shop to NIST and audited by the ARR annually. Knowing I have a good accurate tool is important to me. The quality of this tool is below the mark. I am surprised as I own VIVOSUN products that are more reliable so I thought I would give it a chance. It lasted almost a year for me.
