5 in 1 TDS/EC/SALT/S.G./Temperature Meter Digital Water - with Backlight

Features:C-100 versatility of portable TDS / EC / SALT / S.G / TEMP water quality tester.Mainly used for testing TDS (ppm /) EC (uS / cm mS / cm) SALT (%) S.G (seawater gravity) and TEMP (C / F)The pen type is simple and portable. Put the meter into the solution it can quickly and steadily respond to the reading and has a calibration function to ensure high accuracy.The density of seawater in different regions is generally 1.02-1.07 and the weight of the dissolved salts is different about 3.5% on average. It is recommended to control the proportion of salt in this range.Seawater salinity is the ratio of the total dissolved solids to the weight of seawater in seawater usually expressed in grams per kilogram of seawater.Specifications:Model: C-100 (with Backlight)/ C-100A (optional)EC:Range: 0 to 10000uS / cm 10.01-19.99mS 20.1-400mS / CMResolution: 1uS / cm; 0.1 ms / cm;Accuracy: 2 ?
