OWSOO 5 in 1 /ECSALTS.G./ Meter Digital Water Quality Tester for Pools Drinking Water Aquariums with Backlight （battery not included)）

Features: C-100 versatility of portable / EC / SALT / S.G / TEMP water quality tester. Mainly used for testing (ppm /), EC ( / cm, mS / cm), SALT (%), S.G (seawater gravity) and TEMP (ºC / ºF) pen type is simple and portable. Put meter into solution, it can quickly and steadily respond to reading, and has a calibration function to ensure high accuracy. density of seawater in different regions is generally 1.02-1.07, and weight of dissolved salts is different about 3.5% on average. It is recommended to control proportion of salt in this . Seawater salinity is ratio of total dissolved solids to weight of seawater in seawater, usually expressed in grams per kilogram of seawater.
