EXTECH EC400 CONDUCTIVITY METER

With the EC400’ s dynamic cell-constant technology it is possible to measure a wide range of Conductivity, TDS, and Salinity with the same electrode. Careful use and maintenance will provide years of reliable service. Features : Autoranging meter offers 3 ranges to measure from pure water to salinity solution to waste, boiler and cooling water using the same conductivity cel 6 selectable units of measure: ¼ S, mS, ppm, ppt, mg/ L, and g/ L Internal memory stores up to 15 labeled readings for easy recall Adjustable Conductivity to TDS ratio factor from 0.4 to 1.0 Self calibration on power up Specifications : Display: 2000 count LCD with Bargraph.
