Hanna Pocket Checker for Iron Testing

Regular price £75.00

The Hanna HI721 Iron Checker gives quick accuate results for the price of a chemical test kit. It uses the phenanthroline method and has an accuracy ±0.04 ppm (mg/L) ±2% of reading and a resolution of 0.01 ppm (mg/L) resolution (250 points). Water quality can be tested and controlled quickly and accurately with these professional quality meters, but at a fraction of the cost of their more sophisticated sister meters in our photometer range. Perfect for control testing in laboratories and for teams of engineers where each operator needs his or her own set of portable test instrumentation, Hanna Checkers have proved hugely popular since their launch in 2010.
