PH Test Strips - 4-9 pH -50pk

Hach pH Test Strips, Mid-Range (4–9 pH units)

Specifically designed for environmental and industrial monitoring, these pH strips cover the range typical of most natural waters. While natural water sources commonly stay above pH 7 due to the presence of carbonates and bicarbonates, many industrial applications—including boiler feed water and swimming pools—require maintaining pH within this specific, narrow window.

Key Advantages

• Targeted Range: Ideal for monitoring natural water sources and industrial systems where precision between pH 4 and 9 is critical.
• Field Ready: Perfect for quick, on-site evaluations of pH levels in both laboratory and outdoor environments.
• Simplified Testing: These strips are easy to use, disposable, and provide an inexpensive alternative to digital meters.
• Immediate Analysis: Obtain results in seconds without the need for additional reagents or complex equipment.
