Extech EC400 Waterproof ExStik Conductivity/TDS/Salinity Meter

One high accuracy multi-range sensor measures four parameters (Conductivity, TDS, Salinity and Temperature)

• Autoranging meter offers 3 ranges to measure from pure water to salinity solution to waste, boiler and cooling water using the same conductivity cel
• units of measure: µS/cm, mS/cm, 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
