A recent hot topic of the Hanna HI702 High Range Copper Checkers previously designed for freshwater being certified to effectively and reliably work for Saltwater as well has got me thinking if any of the other Hanna Checkers could be used with reliable results in the Marine Hobby. For instance can the readily available HI700 Freshwater Ammonia Checker also provide more reliable results that the currently available color charts on the various test kits that we use now? @Hanna Instruments, what say you?
