Digital Salinity Tester for Salt Water - Waterproof IP67 Salinity Meter with ATC Large Range 0-200ppt Saltwater Tester for Seawater, Aquariums, Marine Monitoring, and Koi Fish Pond by ORAPXI

Product Information

HI-763133 stainless steel, four-ring conductivity/TDS probe with internal temperature sensor and 1.5 m (4.9’) cable (included) Choose from seven memorized standards and obtain up to a five point conductivity calibration. For salinity (% range), HI-7037 standard allows users to perform a one point calibration. USP <645>

The probe should be rinsed with purified water each time before placing in calibration solution or sample to be tested Salinity is an important measurement in seawater or in estuaries where freshwater from rivers or streams mixes with salty ocean water since aquatic organisms have varying abilities to survive and thrive at different salinity levels. Saltwater organisms survive in salinity levels up to 40 ppt, yet many freshwater organisms cannot live in salinity levels above 1 ppt. 2 Boyer, T.P.; Antonov, J.I.; Baranova, O.K.; Coleman, C.; Garcia, H.E.; Grodsky, A.; Johnson, D.R.; Locarnini, R.A.; Mishonov, A.V.; O’Brien, T.D.; et al.

H1If using a glass hydrometer, the measurement will be where the surface of the water touches the meter – make sure you measure the flat water surface, not the meniscus.

The salinity tester is supplied complete with batteries and solutions allowing you to start measuring right away. Also displays temperature. Unlike pH meters, salinity meters don’t require frequent calibration. Depending on use, calibration of a salinity meter can be done once every three or four months or manufacturer's on how to care for one. If your probe is continuously submerged in your filter sump, it’s especially important to make sure the probe tip is not covered with slime, algae or other debris. The two electrodes are fairly rugged. You can wipe down the outside of the probe body with a soft cloth and RO water. If the electrodes look dirty, gently remove debris with a soft brush and RO water. You can let the device float on the swimming pool without worrying about it sinking at the bottom of the pool and retrieving it during testing.

The IP67 rated waterproof housing, study design, and quality construction will provide durable operation in even the toughest saltwater environments.

They are useful in a wide range of applications from testing salinity levels in water used for agriculture, drinking water, wastewater, and for testing the water in home pools and spas.

[ Google Scholar] [ CrossRef][ Green Version] A river or lake water with a salinity of around 70mg/L will typically have a specific conductivity at 25 °C of between 80 and 130 μS/cm. The actual ratio depends on the ions present. [14] The actual conductivity usually changes by about 2% per degree Celsius, so the measured conductivity at 5 °C might only be in the range of 50–80 μS/cm. Killing aquatic organisms that require low or specific salinity levels, or they will need to learn to adapt to changes, however, not many species can do this.Kaidarova, A.; Marengo, M.; Marinaro, G.; Geraldi, N.; Duarte, C.M.; Kosel, J.

Aside from measuring salinity level on your swimming pool, it can also read water temperature as you measure the salt on your pool.
