Oakton EcoTestr CTS1 Waterproof Pocket Conductivity, Salinity, and TDS Tester (each)

Economical TDS pocket meter features a large, ergonomically designed display so that you can easily view measurements at a glance. The orientation of the display means there’s no need to turn your head or tilt the tester. Waterproof and dustproof housing is designed for use in dirty and damp field conditions. Convenient, built-in belt/pocket clip keeps the tester accessible when not in use.

Stainless steel electrodes are both rugged and chemical resistant, for use in a wide variety of applications. Single-point electronic calibration means you are ready to measure quickly and easily. Additional features include auto-shutoff to prolong battery life, hold function to lock in a measured value, and self-diagnostic error messages. Tester also has a self-adjusting TDS factor from 0.40 to 1.0.

This new addition to the Oakton EcoTestr product line features updates to make measuring water quality easier and faster. The display is larger with a better viewing angle, has indicators for battery life, readiness, and calibration, and shows both the parameter and temperature readings at the same time.

To enhance field use, the cap was redesigned to be leakproof and can be attached to the top of the meter when not being used—no more lost caps! The cap features a fill line, so you know how much sample you need for an accurate reading when using the cap as a sample cup. It is also wider, providing a base to keep the meter upright for hands-free measurements.

The keypad now has a fourth key to simplify menu navigation while keeping convenient one-touch calibration. The new housing is compatible with lanyards to prevent losing or dropping, but is still waterproof and floats just in case.

• Low-cost tester is perfect for applications where lost or broken meters are a concern
