Product description

The Hanna HI755 Checker Photometer is a compact and accurate digital meter for measuring alkalinity (KH) in saltwater and marine aquariums. The HI755 is specifically designed for saltwater applications and is not suitable for freshwater testing.

Unlike conventional chemical test kits and test strips, the HI755 eliminates the need to visually compare colours. The checker uses a fixed-wavelength LED light source and a light detector to perform the measurement digitally. The result is clearly displayed on the LCD screen, making alkalinity testing quick, simple and consistent.

With its compact size and lightweight 64 g design, the HI755 Saltwater Aquarium Alkalinity Checker is easy to handle and convenient to carry. Operation is straightforward thanks to a single control button, while the automatic shut-off helps extend battery life.
