The HI96822 displays results in three popular measurement units: Practical Salinity Units (PSU), salinity in parts per thousands (ppt) and specific gravity (S.G. (20\/20)). The instrument's high accuracy and simple operation gives reliable results each and every time. All readings are automatically compensated for temperature variations and displayed within a 1.5 second response time. The sealed flint glass prism and stainless steel well are easy to clean. Just wipe with a soft cloth in preparation for the next sample.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSample size as small as 2 metric drops (100 μl)\u003c\/li\u003e\n\u003cli\u003eSealed stainless steel well with high-grade optical prism made of flint glass\u003c\/li\u003e\n\u003cli\u003eFast 1.5 second response time for temperature compensated readings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv class=\"grid-x grid-padding-x grid-padding-y\" data-detail-item=\"\"\u003e\n\u003cdiv class=\"cell small-12 large-auto\"\u003e\n\u003cp\u003eThe HI96822 Digital Refractometer eliminates the uncertainty associated with mechanical refractometers by measuring the refractive index to determine the salinity of natural and artificial seawater including brackish, ocean water or saltwater aquarium. The instrument converts the refractive index of a sample to PSU, ppt and specific gravity. These conversions are based on respected scientific publications using the physical properties of seawater (not sodium chloride). The HI96822 is an easy to use tool for measuring salinity in natural and artificial seawater whether in the field, lab or at home.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDesigned for seawater salinity analysis (not NaCl)\u003c\/li\u003e\n\u003cli\u003eAutomatic Temperature Compensation\u003c\/li\u003e\n\u003cli\u003eHigh accuracy measurements displayed as PSU, ppt and specific gravity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"grid-x grid-padding-x grid-padding-y\" data-detail-item=\"\"\u003e\n\u003cdiv class=\"cell small-12 large-auto\"\u003e\n\u003ch4\u003eMaking a Standard Solution\u003c\/h4\u003e\n\u003cp\u003eSodium Chloride solutions can be used to check the accuracy of the meter.
