Refractometer - Salinity with ATC , 28% L1-Mathematics-L2-Classroom Resources and division facts for numbersThis precision salinity refractometer is engineered to provide accurate, fast, and reliable measurements of sodium chloride (NaCl) concentration in water based solutions, such as seawater and food preparation brines. It features an Automatic Temperature Compensation (ATC) system, allowing consistent results even when ambient temperatures vary making it highly suited for field or laboratory testing environments. Its triple scale readout provides
