Oakton® 50 Series
Conductivity Pocket Testers

New design stands up to the challenges of
measuring water quality—even stands upright

The Oakton conductivity pocket testers stand up to everyday
use, harsh environments, and the test of time. The testers can
even stand upright when the cap is used as the stabilizing
base. When you choose one of these conductivity testers,
you get a pocketful of useful features and benefits.

- Easy-to-replace sensor module lets you use the tester body

over and over again

- Intuitive interface has self-diagnostic error messages, and

battery-life and stable reading indicators

- Simple operation at your fingertips with MENU button, 1-button

calibration, and HOLD button to freeze readings for recording

®

- Valox

- Leakproof cap functions as a sample cup, hydrating cup,

- Uses common AAA batteries

body resists most chemicals and is rugged, dustproof,

waterproof, and IP67 rated

and stabilizing base to stand the tester upright

Cap Design: versatile and functional

Tester stands upright

with wide, stable

base
