Maintaining pH Levels

The measurement of pH is very important in the disposal of industrial waste, especially where sewage or chemicals are entering a stream or river. Regularly testing the pH where the wastepipe enters the water ensures that the neutrilizing material is working. The portable pH PAL tester from ETi (UK) is ideal for monitoring pH levels without the need of litmus paper. The pH PAL tester is a reliable, robust and easy to use instrument that indicates pH over the range of 0 to 14pH with a resolution of 0.1pH and an accuracy of ±0.2pH. The unit features an easy to read LCD display and incorporates a manual calibration feature and automatic temperature compensation over the range of 0 to +50°C.
