Description
EziLab's Portable Water Quality Analyzer EZL-PWA10 measures COD from 10 to 15000 mg/L by the potassium dichromate method, alongside ammonia nitrogen, total phosphorus, and total nitrogen, using an LED light source at 420, 520, and 620 nm with accuracy within 5% and repeatability within 3%. Intelligent power-saving, a 300-seat data log, and a compact 300g body make it easy to hold and carry between sample points, while zero drift stays under 0.3% full-scale per 30-minute interval for stable field readings. As a COD analyzer built for on-site work, this unit lets field teams get organic pollution results without shipping samples back to a central lab. Aquaculture operations use it to track pond water quality alongside oxygen demand, while wastewater treatment plants rely on the same water quality meter for influent and effluent checks across treatment stages. Municipal water authorities apply it to spot-check distribution points, and industrial wastewater monitoring programs use the multi-parameter range to catch permit violations early. Environmental monitoring teams covering wide sampling areas favor a portable water tester like this one to cut lab turnaround from days to minutes. See the Portable Water Quality Analyzers and Portable Water Quality Analyzer pages for further specifications and ordering details.
