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 and any aqueous solution requiring a conductivity TDS or Salinity measurement
• 6 units of measure: µS/cm, mS/cm, 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 value
• 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 °C
• Simultaneous display of Conductivity, TDS, or Salinity plus Temperature
• Internal memory stores up to 15 labeled readings for easy recall
• Self calibration on power up
• Easy to replace Conductivity cell module
• Waterproof design to withstand wet environment - meet IP67 standard
• EC400 includes meter and conductivity cell, protective sensor cap, sample cup with cap, four SR44W button batteries and a 48" neck strap
• EC410 Kit includes EC400 meter, with sensor, protective cap, 84uS/cm, 1413uS/cm and 12880uS/cm calibration standards (30mL each), weighted base, 3 sample plastic cups with caps, four 3V CR-2032 button batteries, 48" neck strap and carrying case
