Lutron PH-224 Economic Pen pH Meter with ATC, IP67 Waterproof

Lutron PH-224 Pen pH Meter

The Lutron PH-224 is an economical, all-in-one pen-type digital pH meter supplied with the PE-12 pH electrode. It measures from 0 to 14 pH with 0.01 pH resolution, while a built-in temperature sensor provides automatic temperature compensation (ATC).

Calibration is automatic at pH 7, pH 4 or pH 10 (up to 3 points) to ensure the best linearity and accuracy, and pH 7.00 and pH 4.00 buffer solutions come as standard. The IP67 waterproof housing, data hold, maximum/minimum recall and auto power-off make it a practical instrument for everyday use.

It suits a wide range of applications, including aquariums, beverages, fish hatcheries, food processing, photography, laboratories, quality control, schools and colleges, swimming pools and water monitoring. The pH electrode is easy to replace.
