INSIZE WQA-P40 Portable Water Quality Analyzer, COD/TP/TN/NH3-N

The INSIZE WQA-P40 is a portable water quality analyzer for testing biomedicine, food emulsion, aquaculture and wastewater samples. Beyond chemical oxygen demand (COD, 5-2000mg/L, ≤±5%), it reads total phosphorus (TP, 0-10mg/L, ≤±3%FS), total nitrogen (TN, 0.05-100mg/L, ≤±5%) and ammonia nitrogen (NH3-N, 0.02-25mg/L, ≤±3%FS), using an LED cold light source across 340, 420, 610 and 700nm with ≤3% repeatability. The supplied digester runs COD at 165°C for 15 minutes and TP/TN at 125°C for 30 minutes each, and testing indicators can be freely combined. Results log to mass storage and transfer through the included PC software. The handheld unit runs on a rechargeable lithium battery.
