Our HI96822 digital seawater refractometer is used to measure salinity via refractometery while our HI98319 waterproof salinity and temperature meter measures salinity via conductivity.\u003c\/p\u003e\r\n\t\u003cp\u003e\r\n\t\t\u003cstrong\u003eWhat is refractometery?\u003c\/strong\u003e\u003c\/p\u003e\r\n\t\u003cp\u003e\r\n\t\tWith our HI96822 salinity determinations are made by measuring the refractive index of seawater. Refractive Index is an optical characteristic of a substance and the number of dissolved particles in it. Refractive Index is defined as the ratio of the speed of light in empty space to the speed of light in the substance. A result of this property is that light will “bend”, or change direction, when it travels through a substance of different refractive index.\u003c\/p\u003e\r\n\t\u003cp\u003e\r\n\t\t\u003cstrong\u003eWhat is conductivity?\u003c\/strong\u003e\u003c\/p\u003e\r\n\t\u003cp\u003e\r\n\t\tConductivity is most commonly defined as a substance’s ability to transmit heat, sound, or electricity. Small charged particles called ions help to carry the electrical charge through a substance. These ions can be positively or negatively charged. The more ions available the higher the conductivity; fewer ions will result in lower conductivity. Also, the higher the conductivity, the higher a solution’s ability to conduct electricity. This is a result of a large number of charged ions present in the solution. Since the various elements used to make up salinity carry an ionic charge, conductivity is used to determine their gross concentration in water.\u003c\/p\u003e\r\n\t\u003cp\u003e\r\n\t\t\u003cstrong\u003eWhat is better for salinity?\u003c\/strong\u003e\u003c\/p\u003e\r\n\t\u003cp\u003e\r\n\t\tWhen comparing conductivity to refractometery to measure salinity, the consensus among the scientific community favors conductivity. This is because there are non-conductive material which can impact the refractive index of seawater but not the actual salt concentration. For example, if we add sugar to artificial seawater, we will see that our salinity value will increase but we have not changed the concentration of salt in the water. If we measured the salinity of that sample with our HI98319 conductivity meter you’ll notice the value is largely unchanged. It is common to have inflated values with a refractometer due to the large number of materials which will affect the density of that water outside of the dissolved salt values. For example, organic waste, sugars, potential non-ionic contaminants or uneaten fish food can increase the values produced on a refractometer but this would be less likely to occur on a conductivity meter like the HI98319. \u003c\/p\u003e\r\n\u003c\/div\u003e\r\n\u003cdiv\u003e\r\n\t \u003c\/div\u003e\r\n\u003cdiv\u003e\r\n\t\u003cdiv\u003e\r\n\t\tSalinity Range\u003cspan style=\"white-space:pre\"\u003e \u003c\/span\u003e0.0 to 70.0 ppt (g\/L); 0.0 to 70.0 PSU; 1.000 to 1.041 S.G.\u003c\/div\u003e\r\n\t\u003cdiv\u003e\r\n\t\tSalinity Resolution\u003cspan style=\"white-space:pre\"\u003e \u003c\/span\u003e0.1 ppt (g\/L); 0.1 PSU; 0.001\u003c\/div\u003e\r\n\t\u003cdiv\u003e\r\n\t\tSalinity Accuracy\u003cspan style=\"white-space:pre\"\u003e \u003c\/span\u003e±1 ppt for 0.0 to 40.0 ppt; ±2 ppt for readings over 40.0 ppt; ±1 PSU for 0.0 to 40.0 PSU ; ±2 PSU for readings over 40.0 PSU; ±0.001 S.G.\u003c\/div\u003e\r\n\t\u003cdiv\u003e\r\n\t\tSalinity Calibration\u003cspan style=\"white-space:pre\"\u003e \u003c\/span\u003eautomatic, single point 35.00 ppt\u003c\/div\u003e\r\n\t\u003cdiv\u003e\r\n\t\tSalinity Temperature Compensation\u003cspan style=\"white-space:pre\"\u003e \u003c\/span\u003eautomatic from 5 to 50.0 ºC\u003c\/div\u003e\r\n\t\u003cdiv\u003e\r\n\t\tTemperature Range\u003cspan style=\"white-space:pre\"\u003e \u003c\/span\u003e0.0 to 50.0°C; 32.0 to 122.0°F\u003c\/div\u003e\r\n\t\u003cdiv\u003e\r\n\t\tTemperature Resolution\u003cspan style=\"white-space:pre\"\u003e \u003c\/span\u003e0.1°C; 0.1°F\u003c\/div\u003e\r\n\t\u003cdiv\u003e\r\n\t\tTemperature Accuracy\u003cspan style=\"white-space:pre\"\u003e \u003c\/span\u003e±0.5°C; 1°F\u003c\/div\u003e\r\n\t\u003cdiv\u003e\r\n\t\tBattery Type \/ Life\u003cspan style=\"white-space:pre\"\u003e \u003c\/span\u003eCR2032 3V Li-Ion (1 pc.)\/ approximately 100 hours of continuous use\u003c\/div\u003e\r\n\t\u003cdiv\u003e\r\n\t\tEnvironment\u003cspan style=\"white-space:pre\"\u003e \u003c\/span\u003e0 to 50 °C (32 °C to 122 °F); RH max 100%\u003c\/div\u003e\r\n\t\u003cdiv\u003e\r\n\t\tDimensions\u003cspan style=\"white-space:pre\"\u003e \u003c\/span\u003e160 x 40 x 17 mm (6.3 x 1.6 x 0.7”)\u003c\/div\u003e\r\n\t\u003cdiv\u003e\r\n\t\tWeight\u003cspan style=\"white-space:pre\"\u003e \u003c\/span\u003e68 g (2.4 oz.) without battery\u003c\/div\u003e\r\n\t\u003cdiv\u003e\r\n\t\tOrdering Information\u003cspan style=\"white-space:pre\"\u003e \u003c\/span\u003eEach meter is supplied with: CR2032 battery (inside the meter), Storage \/ Protection sleeve, Instruction manual, Quality certificate, and 35.00 ppt calibration standard sachet (4 pcs.)\u003c\/div\u003e\r\n\t\u003cdiv\u003e\r\n\t\tWarranty\u003cspan style=\"white-space:pre\"\u003e \u003c\/span\u003e1 year\u003c\/div\u003e\r\n\t\u003cdiv\u003e\r\n\t\tMethod\u003cspan style=\"white-space:pre\"\u003e \u003c\/span\u003eppt - International Oceanographic Tables; PSU - Standard Methods for the Examination of Water and Wastewater, 2510 B, Electrical Conductivity Method; S.G.- Standard Methods for the Examination of Water and Wastewater, 2510 C, Density Method\u003c\/div\u003e\r\n\u003c\/div\u003e\r\n\u003cp\u003e\r\n\t \u003c\/p\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":41721707757614,"sku":"HI-98319","price":99.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0583\/4276\/8686\/files\/15446.jpg?v=1765980814","url":"https:\/\/mattscorals.com\/products\/hanna-hi-98319-waterproof-salinity-tester","provider":"Matt's Corals","version":"1.0","type":"link"}
