Extech EC400
ExStik® Conductivity/TDS/Salinity Meter

Waterproof meter with one high accuracy multi-range
sensor that measures four parameters

• Autoranging meter offers 3 ranges of measurements from tap water to wastewater and any aqueous solution requiring a conductivity measurement, plus salinity using the same conductivity cell
• 6 selectable units of measure: µS, mS, ppm, ppt, mg/L, and g/L
• High accuracy multi-range conductivity cell measures Conductivity, TDS, Salinity, and Temperature
• Adjustable Conductivity to TDS ratio factor from 0.4 to 1.0 - conveniently calculates the TDS and Salinity values when ratio factor is selected
• Large 3-1/2 digit (2000 count) Digital display with analog bargraph to indicate sample trends
• Data Hold, Auto Power off and low battery indication
• Automatic Temperature Compensation of 2% per degree
• Simultaneous display of Conductivity or TDS plus Temperature
• Internal memory stores up to 15 labeled readings for easy
  recall 
• Self calibration of electronics on power up
• Easy to replace Conductivity cell module
• Waterproof design to withstand wet environment
