pH2+ EcoTestr Pocket Meter

  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.

Easy to carry, simple to operate and sufficient for most field pH tests

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.

Our selection of handheld pocket testers includes the following models:

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.

pH Testr 10 -  Has a Range of 0 to 14 with an Accuracy of ±0.1 pH and has a replaceable, double-junction electrode, which is designed for use in harsh environments and provides better long term accuracy. The replaceable sensor allows the user to replace the worn out sensor without throwing away the advance electronics within the existing tester, saving both time and money.

pH Testr 20 -  Has a Range of 0 to 14 with an Accuracy of ±0.01 pH — includes all the features of the pH10 and due to the increase accuracy is suitable for most ASTM and EPA test procedures.

pH Testr 30 -  Has a Range of -1 to 15 with an Accuracy of ±0.01 pH— includes all the features of the pH20 and is the most flexible instrument for sampling of pH and temperature. Consider the pH30 as an advanced pH meter that fits in the pam of your hand and at half the cost of most handheld meters.
