Review on 🧪 Hanna Instruments Salinity Tester HI98319: Accurate Salinity Measurement Made Easy by Kory Shelton

Do not recommend ordering this item. The goods came clearly used (see photo). This shows that someone tried to hack into the battery compartment and scratched the plastic case in two places. The teeth that work in the water are covered with some kind of black coating. The whole tester is scratched. Also, the instructions say to remove the plastic around the battery to allow it to turn on. there isn't even any plastic on it because the previous user took it off!
