Providing value without compromise, Oakton® EcoTestr™ 1 Series waterproof testers are easy to use and read. The large, dual-line LCD provides measurement and temperature information, as well as current battery life. The two-button interface allows for simple navigation of the meter menus and quick sample measurement. Designed to float in water, they are ideal for field testing applications such as lakes and streams – you can even attach a line to the housing for easy retrieval.

Additional features include a long-lasting durable electrode with polymer reference electrolyte; status icons for measurement stability, calibration, and battery life; and self-diagnostics. The leakproof cap with fill line functions as a sample/calibration and hydrating cup. The tester, powered by four AAA batteries, can operate for up to 400 hours continuously. The unit will auto power-off after 8 minutes of nonuse to conserve power.
