  • Instant pH readings
  • Diverse ranges offered
  • pH Indicators are portable for convenience
Accurate for a wide range of routine pH testing. Plus, they are convenient and portable for field use. Color Bonded pH Strips (Nos. 53279 and 53280) are plastic-supported strips with four different segments of dye-impregnated indicator papers. The combination of color differences results in clear and accurate visual pH values. Dyes are chemically bonded to paper and cannot leach into solution—avoids any problems or contamination.
Each Integral Comparison Strip (Nos. 53281-53287) has a central segment of indicator dye and, printed alongside, eight or more different color segments marked with corresponding pH values for direct matching purposes. Great for colored solutions where any changes in color of the paper stock are automatically canceled out.
Three-Color Dispenser (No. 53288) has three separate indicator dye color bands. The unique combination of color change resulting from each test is compared with the color-coded comparison chart printed on the dispenser.
A Full-Range (No. 53289) and four Narrow-Range (Nos. 53290-53293) are available in a Standard Dispenser format. All color changes are distinct and clear.
