Product Introduction:
The BLA-NH3-500 ammonia nitrogen water quality online automatic analyzer is based on our patented magnetic conductivity measurement platform, combined with technologies such as constant temperature optical fiber and digestion colorimetric integration, to achieve high-precision, low detection limit, high stability, and low maintenance ammonia nitrogen fully automatic online monitoring. The working principle of this product complies with the technical requirements of "HJ 536-2009 Determination of Ammonia Nitrogen in Water Quality - Salicylic Acid spectrophotometric method", fully meeting the applications in pollution sources, industrial production processes, municipal sewage and other fields. Certified by CPA and CCEP.
Product Features:
Magnetic conductivity measurement technology is not affected by interference such as high chromaticity, suspended solids, and bubbles;
High reliability, strong resistance to chromaticity and calcium magnesium ion interference;
High detection accuracy, low quantification limit (0.01mg/L), and small long-term drift of the instrument;
Equipped with one click self-test function and self diagnostic function;
Single channel highly integrated valve island, capable of single valve maintenance, disassembly, and cleaning;
Scalable 24/7 networking function, monitoring instrument operation status anytime, anywhere;
Equipped with alarm function, quality control function, and reverse control function.
Product Application:
Widely used in environmental pollution source monitoring, industrial process water monitoring, municipal sewage treatment, surface water monitoring, etc.
