pH Acidic Test Strips 3.0-6.0
Use pH acidic test strips in the range of 3.0-6.0 for measuring relatively weak acids such as acetic acid (vinegar) or for preparing buffers
in the same range. They are also useful for homebrewers, especially beer, which can be in the range of 3.9-4.6 (give or take). These strips are also recommended for testing
for the presence of yeast infections which generally appear in the 3.8-4.2 range.
The pH indicator pads are mounted on rigid, high contrast white plastic and are convenient for testing in the field, lab or home.
Note: The number of strips per pack or vial is approximate.
- Narrow pH range 3.0-6.0; resolution is 0.5 pH unit
- Test vinegar (acetic acid) or beer or wine
- Confirm a yeast infection
Test Specifications; How to Use
- Dip strip in solution for 1-2 seconds; compare to color chart
- Solutions must be aqueous (water based)
- For soaps, wet the strip first; oils cannot be tested
- Deeply colored solutions can cause inaccurate readings
