Field pH Meters

Field pH meters, pH testers, and pH electrodes are essential tools for accurately measuring the acidity or alkalinity of various samples in outdoor and laboratory settings. These devices are vital for scientists, researchers, and professionals who require precise pH readings.
Complementing this lineup, chlorine meters, especially digital chlorine meters, offer a specialized function for testing chlorine levels in water, ensuring safety and compliance with health standards. The key benefits of using these instruments include their portability, ease of use, and the ability to obtain immediate, accurate readings in various environments. Digital models provide clear, easy-to-read displays, making data collection more efficient and reliable.
Together, these tools support a wide array of scientific and environmental studies, contributing significantly to water quality monitoring and research efforts.

Thomas carries a large selection of benchtop and portable pH meters for all your pH testing needs. Find the pH Meter or pH Tester best suited to your application.
