pH Meters

pH Meters are essential instruments for measuring the acidity or alkalinity of aqueous solutions, playing a crucial role in water treatment, scientific research, food production, and industrial processing. At Wasteless Bio, we offer a wide range of precision pH meters designed to deliver accurate, reliable, and reproducible pH measurements across various applications—from laboratory experiments to environmental field testing and industrial quality control. pH is a vital parameter that influences chemical reactions, microbial activity, corrosion rates, and product stability. Whether you're monitoring the pH of drinking water to comply with regulatory standards, optimizing buffer solutions in a biotech lab, or maintaining the correct pH levels in fermentation, plating, or agricultural systems, a dependable pH meter is a critical tool in your workflow. Our inventory includes benchtop pH meters for laboratory use, portable handheld meters for on-site field testing, and inline pH sensors for continuous process monitoring in industrial systems. Many of these meters also feature multi-parameter capabilities—allowing for simultaneous measurement of temperature, ORP (oxidation-reduction potential), and conductivity. This makes them ideal for complex analytical and monitoring tasks. Wasteless Bio frequently lists pH meters from top-tier manufacturers such as Mettler Toledo, Thermo Fisher Scientific, Hanna Instruments, Hach, and Eutech Instruments. Each unit is inspected and verified to ensure functionality, and listings include specifications such as measurement range, accuracy, calibration method, and probe type to help users find the best fit for their specific needs. Purchasing repurposed or surplus pH meters from Wasteless Bio allows laboratories, treatment facilities, and production plants to access high-performance equipment at a significantly reduced cost. Plus, it aligns with sustainability objectives by extending the lifecycle of scientific instruments and minimizing environmental waste. For accurate, cost-effective pH measurement in any setting, explore our selection of trusted pH meters and maintain optimal control over your water or process chemistry.
