Description

The Extech PH100 and PH110 pH meters come complete with flat surface pH electrodes, protective sensor caps, sample cups with caps, four SR44 button batteries, and 48" (1.2m) neck straps.

Extech PH100 pH Meter

The waterproof Extech PH100 pH meter has a flat surface electrode for measuring pH in liquids, semi-solids, and solids. A built-in smart chip offers advanced functions and features not found on any other handheld pH meters.

The Extech PH100 pH meter is equipped with features that make taking accurate measurements of pH levels simpler and more reliable than ever before. Extech's RENEW indicator eliminates guesswork and tells you when it's time to replace your pH electrode. The CAL feature tells you when it's time to recalibrate your meter. The Extech PH100 pH meter also has a large digital display that indicates pH level and temperature and includes an analog bar graph that indicates pH trends in acidity or alkalinity from a neutral point (pH 7.00). The Extech PH100 pH meter also features automatic temperature compensation, data hold, auto power off and low battery indication. A display indicates when the reading is stabilized.

The Extech PH100 pH meter is a precision instrument that measures pH from 0.00 to 14.00pH with a resolution of 0.01pH and accuracy ±0.01pH. The Extech PH100 pH meter also measures temperatures from 23°F to 194°F (-5°C to 90°C) with an accuracy of ±1.8°F. The Extech PH100 pH meter is completely waterproof (IP57)and rugged enough to withstand harsh environments.

Extech PH110 pH Meter

The Extech PH100 is also available in a refillable model, the Extech PH110 pH meter, which features the same specifications as the PH100 but has a pH electrode that can be reused by refilling the reference solution once it is depleted. Refilling the electrode allows users to obtain continuously high accuracy by using fresh reference solution. The Extech PH110 pH meter also eliminates the concern of electrode shelf life.
