Review on 🔬 Enhanced Precision with HM Digital Dissolved Resolution Accuracy: Elevating Water Testing Standards by Jose Miller

To get straight to the point, it can take up to 3 minutes for this meter to read an accurate temperature. This is really the only issue I've had, but it's a design consequence so I can't fault it. Filter and you're not just checking how good your filter is, get something like this. These meters are only calibrated to be accurate in the 0-500ppm range. Outside the case, the gauge was wrong by 25 parts per million. But after it was calibrated I still had no problems. The meter works as expected and is very easy to calibrate when I need it. All in all a very reliable meter and I am happy with my purchase.
