“Perfect readout for my phosphate level! The old API test was just to high range and difficult to read. The Hanna unit is a little pricey, but well worth it for the long haul.”
“It arrived in a damaged box with a flat battery. When I used the checker it failed to detect high levels of iodine. I know they were high because I put some into the water after the first test showed zero levels. Having said that, I love my other Hanna Checkers. I already own three of them.”
