4/16/09 - R1

Waterproof meter with one high accuracy multi-range sensor

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

• Waterproof design to withstand wet environment – meets IP57 standard

• EC400 includes meter and Conductivity cell*, protective sensor cap,

sample cup with cap, four CR2032 button batteries, and 48"(1.2m) neckstrap. Order Conductivity standards separately

• Optional EC410 kit includes EC400 ExStik® II

Conductivity/TDS/Salinity/Temperature Meter, with sensor, protective cap, 84μS/cm, 1413μS/cm and 12880μS/cm calibration standards (30mL bottle each), weighted base, 3 sample plastic cups with caps, four 3V CR-2032 button batteries, 48" (1.2m) neckstrap, and carrying case
