10 month old Hanna Marine Monitor - keeps tabs on Salinity, Ph and Temp. Purchased as triple check as I thought my Apex probes and Ph test kits were out of wack. All were in line - was just high CO2 in my house causing low Ph. Get peace of mind https://www.hannainst.com/marine-ph-ec-temperature-monitor-hi981520-01.html
You will need salinity calibration fluid. I have extra Pinpoint 7 & 10 ph calibration fluids to throw in. Pick up in Hopkinton.
