pH meters and ion meters measure the water quality parameters critical to many laboratory, industrial, chemical, and processing applications. Whether you are performing water analysis in the lab or field, we have the pH meter to meet your needs. Pocket-sized testers are an economical alternative for routine measurements. Handheld portable meters are ideal for field, manufacturing floor, and lab. Benchtop meters are the choice for high-accuracy pH measurements on the lab bench. Specialty pH/mV meters plus ISE electrodes and ISFET electrodes handle specific ion applications or harsh environments.
