‘Baker-pHiX’ pH Papers with color scale are a series of indicator papers having the indicator dye and color scale conveniently combined and fixed onto a single paper strip. This allows for enhanced accuracy and readability since the pH indicator and the color scale are wetted simultaneously. This benefit is even more important when testing colored solutions. Papers encompassing the complete range have pH graduations of 1.0 unit. Intermediate range papers have pH graduations of 0.5 units and narrow range papers are available with pH graduations of 0.2-0.3 units. Each strip measures 11 x 100 mm. They are packaged in easy-to-use plastic boxes, each containing 200 strips.
