Review on 🌡️ HoneForest Temperature 0 9990PPM Aquariums: Ensuring Precise and Reliable Temperature Monitoring by Bryan Turner

Just received this today; So I can't say anything about long-term reliability. However, it worked great right out of the box. I tested the following samples: pool water, kitchen water, filtered refrigerator water, bottled spring water, and distilled water. Distilled water was the first thing I tested and it read zero; as expected. Each time I tested a sample, I put the tester back in the distilled water to clean it and tested the distilled water again. As I went through the test and cleaning cycle, the distilled water level increased slightly (by 1-2ppm) with each rinse. I tested all samples twice and got the same result; that means it fits. The distilled water rose to 5ppm after rinsing in the first test run and was at 12ppm after my last test run. I was expecting some increase in ppm since I purify hard water into distilled water; I think this is a very good representation of the accuracy of this tester. As a final test, I checked a fresh glass of distilled water and it got a zero reading. I think I tested the accuracy of this tester pretty thoroughly and I was very happy with the results. I also checked the temperature of my five samples after they had been stored for about 20 minutes; They were all within 0.5 degrees Fahrenheit. So far this tester is working exactly as it should and I am now very confident in its accuracy. It appears to be assembled fairly well and has a nice carry case. As I said in my title; "It's a winner."
