that measures four parameters
Conductivity, TDS, Salinity, and Temperature
ExStik
®
II Conductivity/TDS/Salinity Meter
Features:
• Autoranging meter offers 3 ranges of measurements from tap water to
wastewater and any aqueous solution requiring a conductivity,
TDS or Salinity measurements
• Units of measure include μS/cm, mS/cm, ppm, ppt, mg/L, and g/L
• 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 25 labeled readings for easy recall
• Self calibration of electronics on power up
• Easy to replace Conductivity cell module
