This newly redesigned SALINTEST™ allows you monitor the concentration of sodium chloride assuring high quality in aquaculture. SALINTEST™ is also ideal for marine fish tanks and aquariums. Instruments for measuring salinity of seawater currently available on the market are cumbersome and difficult to use. Hanna has re-engineered this compact salt tester with a more durable, ergonomic casing and with a larger LCD. Besides applications in aquaculture, SALINTEST™ is also ideal for checking salt concentrations in live fish storage tanks, tropical fish aquariums, refrigerated storage and oceanographic investigation. SALINTEST™ comes supplied with a handy chart that will convert your sodium chloride readings into grams per liter. Range: 0.00 to 1.00 pNaCl (58.4 to 5.84 g/L of NaCl). Resolution: 0.01 pNaCl. Accuracy (@20°C/68°F): ±0.02 pNaCl. Typical EMC Deviation: ±0.04 pNaCl. Calibration: Manual 1 point through trimmer. Battery Type / Life: 4 x 1.4V / 500 hours approx. continuous use. Environment: 0 to 50°C (32 to 122°F); RH 95%. Dimensions: 175 x 41 x 23 mm (7.9 x 1.8 x 1"). Weight: 78 g (2.7 oz.). Hanna # HI98203. Capitol # W3910.
