Published May 02, 2026 at 07:10 pm (Order date: Apr 23, 2026)The mini photometer perfectly fulfilled its mission of measuring the iron content of my heating water. Follow the testing procedure closely and clean the test tube well after each measurement. (Translated review)

Published Nov 28, 2025 at 05:05 pm (Order date: Nov 18, 2025)It gives perfect accurate values. I use it for a planted aquarium, it's light years better than my previous cept tests. It's more expensive, but I wish I had bought it 10 years ago....
