Simple one-hand operation provides an economical alternative to traditional meter and probe technology. Highly stable and accurate readings with a large LCD display. Automatically calibrates to pH 4, 7, 10 buffers and can be adjusted to recognize non-standard buffers as well. These pH pens offer unbeatable solutions for applications such as waste-water, surface water, aquaculture, hydroponics, pools, and education. They each feature automatic temperature compensation (ATC), hold function, and auto power off with low battery indicator. The cases will float if accidentally dropped into the water. They come with 4 button-cell batteries and a built-in electrode kept moist with a protective cap.

EcoTestr pH 2+ has a range of 0 to 14 with an accuracy of +/-0.1 pH and is the perfect instrument for economical spot sampling of pH and temperature. The water tight sample cap keeps the electrode hydrated and eliminates downtime waiting for it to rehydrate. Has nearly double the standard life span of a competitor's basic tester.
