Guaranteed Safe & Secured Checkout

Check acidity and alkalinity without relying on hard-to-match test-strip colors. This compact pocket pH tester measures from 0.0 to 14.0 pH and displays results in 0.1 increments. Its pen-shaped body travels easily between tanks, pools, and sample containers. Simple controls and manual calibration make it practical for routine water checks.

Key Features

  • Full 0.0–14.0 pH measurement range
  • 0.1 pH display resolution
  • Manual one-point calibration with adjustment trimmer
  • Portable LCD design powered by button cells

Why Choose Our AquaPen PH-009 IA

Unlike disposable strips, this aquarium water tester provides reusable numerical readings without color interpretation. Its slim design is convenient for hobbyists, students, and anyone checking several water sources.

Perfect For

Ideal for aquariums, swimming pools, spas, hydroponics, ponds, laboratories, drinking-water systems, and beverage preparation.

How to Use

Calibrate with fresh buffer solution before first use. Rinse the electrode with distilled water, immerse only to the marked level, stir gently, and wait for a stable reading. Rinse after testing and replace the cap. A pH result alone cannot confirm that water is safe to drink.

Make Every Water Check Clearer

Choose the AquaPen PH-009 IA for simple, portable pH monitoring wherever you need it.
