Review on 📈 High Accuracy Digital pH Meter with ATC Tester - 3 in 1 Pen Type for Water, Wine, Spas, Aquariums - 0.01 pH Resolution, TDS & Temp Measurement by Justin Miller

UPDATE: When I purchased the counter I received what appeared to be a Revain gift card in the box with the Revain logo. After I contacted the company to get the card, they asked me to write a review for this switch and sent them the details of my order. After 3 months of dealing with them, they have no intention of redeeming the gift card. They claim I returned the meter. They also stated that if the gauge broke they would not honor my warranty. My original review is below; I still have a blood glucose meter and use it often. He was never returned. The seller is unreliable. I wish I knew that sooner. I would buy a PH meter from someone else. The Revain title above my review clearly states that this is a verified purchase. I will not buy from this seller again and will not recommend to anyone. * * * * * * * This is a good counter, well made, good size and durable. When measuring the PH value of tap water, the readings are stable, when measuring my hydroponic water, the readings jump a bit, but are very easy to read. The backlight is nice and the display is easy to read.
