Multi-parameter Water Quality Online Detection Instrument Implemented by Spectrophotometry
Addressing the limitations of traditional spectrophotometric water quality online detectors,which face issues such as limited detection parameters,low efficiency,and interference from ambient temperature on the light source,we have designed an efficient and rapid multi-parameter water quality online detector.This instrument targets the detection of total phosphorus,CODCr,and ammonia nitrogen.By optimizing the detection process,the efficiency of these three parameters has been significantly improved.Additionally,a dual-beam measurement method is employed to compensate for the impact of ambient temperature on the light source.Performance testing has demonstrated that this instrument outperforms national standards in key performance indicators such as indication error,repeatability,zero drift,and span drift.
