The NH6000sc online ammonia analyzer (photo) is designed for installation in wastewater applications in outdoor locations. By designing the unit to have reagents conveniently located right inside the door, the bottles can be easily accessed and replaced. With reagents lasting up to six months, maintenance is made significantly simpler. Setup is also streamlined, because no separate compressor or pump is required. The NH6000sc offers accurate low-range monitoring, providing stable ammonia values, even at concentrations less than 1 mg/L. The unit employs a gas-sensing electrode with automatic calibration and cleaning functionalities, as well as weatherproof housing and an optional integrated filtration system. — Hach Co., Loveland, Colo.
