Review on 🌡️ Enhanced YSI Dissolved Oxygen Temperature Degree Sensor for Accurate Readings by Robert Long

They work well when they work. We are in fifth place, two of them are eliminated. In our humid working environment, each of them was exposed to moisture. Two were returned due to moisture, one was repaired under warranty, the other was denied warranty. I was offered a replacement for several hundred dollars above retail price. Buyers beware: If you are in a humid environment, there will be moisture in the LED reading area and the warranty service will be inconsistent.
