pH Test Reagent Strips STANLEY GHM PH7 – 5 strips (indicator for measuring pH)

STANLEY GHM PH7 reagent pH test strips, pack of 5, provide a quick colorimetric indication of pH for aqueous solutions. These strips are designed for rapid, routine checks where a visual estimate of acidity or alkalinity is required. Compact and simple, the strips are suitable for basic water testing, laboratory spot checks, classroom demonstrations and process control tasks that do not require instrument-grade precision.

Advantages

The test strips offer fast results through an easy-to-read color change, eliminating the need for calibration or power. They are portable and require minimal storage space, making them convenient for fieldwork and mobile testing. Their simple format reduces training time for users and enables repeatable, on-the-spot pH estimation for routine monitoring.

Suitable for

• General water quality checks (tap water, aquarium water, wells)
• Laboratory quick spot tests and sample triage
• Educational demonstrations and classroom experiments
• Basic process control where approximate pH values are sufficient

Key specifications

• Format: paper reagent strips with pH-sensitive indicator
• Quantity: 5 individual strips per pack
• Measurement principle: colorimetric pH indication
• Typical use range: suitable for aqueous solutions (check color chart for range limits)
• Result type: visual color comparison against reference chart

How to use

Dip a single strip briefly into the test liquid or apply a drop of the sample onto the reactive area, then remove and hold the strip horizontally. Wait the specified reaction time and compare the resulting color to the included reference chart under good lighting. Record the approximate pH value indicated by the closest matching color. Follow any handling notes printed on the strip packaging to avoid contamination and ensure consistent results.

Usage recommendations

Store strips in their original packaging in a dry, cool place away from direct sunlight and volatile chemicals. Use unopened strips before the expiration date and discard any strip that has been exposed to moisture prior to use. For applications requiring high accuracy or traceable results, confirm readings with a calibrated pH meter or laboratory titration.
