Product Description
Measurement Principle
This instrument adopts the phosphorus vanadium molybdenum yellow photoelectric colorimetry. According to the Beer-Lambert Law, when a monochromatic light with corresponding wavelength passes through a colored solution, the light intensity will decrease because part of the light is absorbed by the light-absorbing particles in the solution. The relationship is as follows:
Where:
² IT is the transmitted light intensity,
² I0 is the incident light intensity,
² L is the liquid layer thickness,
² C is the solution concentration,
² K is a constant.
This is the Beer-Lambert Law, and the instrument analyzes and calculates the measured substance in the water sample based on the above formula.
Features
² Advanced embedded single-chip microcomputer technology;
² Compact structure, panel-mounted, full aluminum frame case, beautiful and sturdy, with strong anti-interference ability;
² Large dot-matrix liquid crystal display, intuitive and rich display content;
² Programmable 1-6 channels switching;
² Programmable modification of channel measurement cycle to effectively save reagents;
² With temperature measurement function, which can compensate measurement data according to temperature;
² Adopts imported light source and photocell, with long service life, small drift, stability and reliability;
² With black box function, which can query historical data, operation records and calibration records;
² Wide voltage (85~265VAC) and wide frequency (45~65 Hz), able to adapt to multiple conditions.
Applications
² In thermal power plants , real-time monitoring of phosphate concentration in boiler feed water and steam condensate to prevent scale formation caused by phosphates, which leads to reduced heat exchange efficiency or equipment corrosion.
² Monitoring phosphate concentration in circulating water or water supply systems in petrochemical, metallurgical and other industries to optimize the dosage of scale inhibitors and prevent pipeline blockage and equipment corrosion.
