Review on 🌡️ High Precision Digital Backlight pH Meter for Water Quality Testing - pH Range 0-14, Ideal for Drinking Water, Swimming Pools, and Aquariums - Designed with Automatic Temperature Compensation (ATC) by Julia Lizeth

Device received, taken out of box, device calibrated with calibration powder included, instructions followed provided. Shortly after, I tested the calibrated device on my tap water, knowing my city water supply is at 7.2 out of the tap. The instrument gave incorrect readings at pH 6.6. Calibrate the device a second time using the same manufacturer's instructions and solutions. After a few moments, after the second calibration, the device reads 7.0 on the exact same tap water. Against my better judgment, I used this device because of all the positive reviews, attributing it to my own user error. Fast forward 10 days and my plants are already showing signs of pH damage so I used my own professional calibration solution and can now unequivocally attest that I would be better off never owning this device and just assuming that my pH levels are like this are because at no point in time has it ever read the correct pH. Needless to say, lesson learned and I now see that you "get what you pay for" when it comes to pH meters - it was a poor decision on my part to risk losing the entire crop due to a faulty 15- spoil dollar pH meters from the start. I will be spending about $100 and will be ordering another BlueLab pH meter soon as I have used their devices in the past with great results and never had a problem with BlueLab in the 6 or 7 years that I have been using them would have. hydroponic cultivation.
