EC400 ExStik® Conductivity/TDS/Salinity Meter by Extech
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
