Conductivity Pocket Testers

For quick, simple water analysis on-the-go.

For use in wate

Product Description

For quick, simple water analysis on-the-go.


For use in water and waste water treatment, boiler blow-down, electroplating rinse tanks, drinking water, hydroponics, printing industry, aquaculture, aquariums, fish farms, swimming pools and spas.


  • Waterproof, anti-roll design – IP67 waterproof housing keeps tester good even under wet conditions. Unique anti-roll ribbed design ensures firm grip.
  • Large display screen – simultaneous temperature read-outs, displays mode, ATC, battery level.
  • Single and multi-point calibrations with automatic or manual options.

Features Specific To EC Tester 11:

  • Dual range with selectable or auto-ranging options – measure in more media with one tester!
  • User replaceable sensor – replace the sensors yourself. Sensors last longer with element made of SS316 stainless steel and sensor casing made of VALOX.

Features Specific To EC Tester 11+:

  • Multi-range with selectable or auto-ranging options – one tester measures from pure water to waste water!
  • Innovative cup-style – sensor housing design can be used as a dip-style or cup-style for holding small volume of samples. Sensor casing is made of VALOX for superior chemical durability.


2 years on the meter and 6 months on the electrode
