Review on 🌊 Ohaus ST20 Waterproof Meter: Accurate Readings in Any Environment by Daniel Aboubakar

High quality meter. For those who say they don't like it or are considering buying it: I work in chemistry for a living and I think it's a great gauge. I have two, the longest of which is about 8 months old. Thin glass electrode. it doesn't "jump" by itself. If it breaks, then it's not the meter's fault, it's the user's fault. Any pH meter must be stored and used properly. After use, rinse with deionized water, then dry with paper towel and store in a cap with 3 M KCl. If you don't do this, it will fail within 6-12 months. If you find that it starts to read data more slowly, you are storing the sensor incorrectly or contaminating it with contaminants like phosphates commonly used in agriculture and aquariums. . Learn how to clean your pH electrode. As a first step, soak the sensor in 5% H2SO4 for 5 minutes, then rinse with deionized water and then treat with 3M KCl. This eliminates phosphate contamination. As such, it's a great gauge, but you have to understand it to use it. Keep in mind that the cheaper $20 gauges may seem more stable, but that's only because they're much less accurate and, in my opinion, essentially rubbish. This is a great meter if you want a near-scientific pH meter for less than $100.
