Acid Rain Test Strips
Kit contains 15 strips of pH test paper and a color comparison chart— designed for measuring the pH of rain in the range of 3.0 to 6.0. A student taking an acid rain survey can take readings on 15 samples.
Lead Testing Paper
Color change of pink to a deep purple-red indicates the presence of lead in solutions or on surfaces. Limits of sensitivity: 0.05 micrograms on surfaces, 5 milligrams/liter (5 ppm) in solutions. The presence of as little as 50 ppb in solution can be determined by using evaporation techniques. Forty 25 x 40 mm size sheets.
