Review on 🧪 Apera Instruments AI311 Premium pH Pocket Tester Kit: Waterproof, with Replaceable Probe for ±0.01 pH Accuracy by Chris Edgerton

My previous review is below. But I'll revisit this point because the meter recently stopped working and communication with the company was disappointing to say the least. I bought this gauge in January and in June it stopped working. I use a meter every day to determine the pH of the water and nutrient solutions for my plants. One day the meter didn't stop at the readings in the nutrient solution. It continued to oscillate until a "smiley face" appeared, meaning the meter read an accurate pH reading. But as long as the smiley is there, he just keeps reading and throwing. I calibrated the damn thing about four times and when I added calibration solutions it gave a stable reading. Add it back to all solutions; Spring water, well water, nutrients, and it just fluctuates. It never stops in the pH range again, it just keeps dropping until a battery saver mode turns the meter off. This was outside of Revain's return period, so I contacted Apera. We tried to film it on the phone. I explained everything to the company in detail. They said it was still under warranty and asked to send it to them for repair and inspection. I paid for shipping. I don't hear from them. I contacted them about the meter and they basically said oh we sent it back. Works fine, calibrated. I finally got the meter back but it's still broken because it seems they haven't fixed the issue. I answered them and they stopped answering so I reported this to Revane and luckily they kindly offered me to come back. Buyer BEWARE! "I highly recommend this PH meter. This is a very easy to use, state of the art gauge. It gives ultra-accurate readings, is easy to calibrate, and comes with starter-sized items you need for storage. and calibration. I use my PH60 every day when gardening."
