Ph/Conductivity Meters

Researchers, technicians, and environmentalists use the pH meter to measure the amount of acid, or hydrogen-ion, in a solution or semi-solid. The meter’s applications include food production, reverse osmosis, pools and spa, and paper industries. A digital meter converts the signal from an electrode or sensor into a reading of each solution’s acidity or alkalinity.

Transcat is your premier provider of pH meters for the best names in the industry, such as Cole-Parmer, Hanna Instruments, and Thermo Electron-Orion. We carry an extensive inventory of test & measurement equipment, with over 3000 products available for same-day shipping. We also offer ISO 17025 Accredited pH Meter Calibration Services, which can be performed on either your current assets or new instruments purchased from Transcat.
