About this item【5-in-1 Water Quality Tester】Salinity Meter, EC Meter, TDS, PH, and Temperature tester. Salinity measurement range: 0~10000ppm/10.1~200.0ppt or 0.0-25%, salinity tester has an ATC function, which can decrease the error caused by the change of liquid temperature.【Two Salinity Meters】Digital PH meter can detect the salinity of edible salt, and it can detect the salinity of seawater too. Food salinity measuring range: 0.00-25.00%, seawater salinity measuring range: 10.1-200.0 ppt, 1%=10 ppt=10000 ppm. TDS and salinity units are the same, but when measuring salinity, the pH meter needs to be converted to salinity mode.【High Precision】The high precision algorithm chip and electrode of our digital ph tester ensure an accurate and fast re.
