Both the HH-1A and DP-1A phosphate analyzers have a measurement range of 0-1.0 mg/L and a resolution of 0.001 mg/L. The HH-1A uses a microcomputer photoelectronic colorimetric principle. The ML801 portable phosphate analyzer has a measurement range of 0-2.0 mg/L. The ML801T benchtop phosphate analyzer features a microcomputer touch keyboard, a backlit LCD display, and an RS-232 interface. The TC-102SY phosphate analyzer conforms to the national standard GB/T5750.5-2006, has a detection time of 15 minutes, a measurement range of 0.0-1.0 mg/L, and uses pulse power supply. The LSY-1A phosphate analyzer has a measurement range of 0-2 mg/L and a minimum reading of 0.001 mg/L. The DP18-102SY phosphate analyzer also conforms to the national standard GB/T5750.5-2006, has a detection time of 15 minutes, and a measurement range of 0.0-1.0 mg/L.
The CHYP-250 phosphate analyzer is a benchtop model with a measurement range of 0.00–25.0 mg/L. It uses an imported high-performance light source and features a large LCD screen with Chinese display. The Orion 2295 phosphate analyzer can be used for online or benchtop measurements, with a measurement range of 0.2–50 ppm and an accuracy of ±5% or ±0.5 ppm. The Orion AquaMate AQ8100 is a benchtop spectrophotometer. The HACH Polymetron 9611sc online phosphate analyzer uses a photometric colorimetric method (vanadium-molybdenum yellow method) with a response time of 5 minutes.
