The HI 718 Hanna Iodine Checker bridges the gap between simple chemical test kits and professional instrumentation. With a resolution of 0.1 ppm (125 points) and ±5% of reading ±0.1 accuracy it provides a clear digital readout of Iodine. Hanna pocket checkers offer a cost-effective digital alternative to chemical test kits. 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.
