Total phosphorus online detection instrument

Model:AME-3030

Method basis: National standards GB11893-89 "Water quality - Determination of total phosphorus - Ammonium molybdate spectrophotometric method"；

Measuring range:0-50mg/L，220V power supply, 4-20mA+485. Size: High800*wide389*deep306mm， Bring a set of reagents and a self-priming pump.

Application Fields

This monitor is mainly used for real-time monitoring of total phosphorus (TP) concentration in surface water, domestic sewage, and industrial wastewater.

Detection principle

Add potassium persulfate solution to the water sample and heat it for digestion for a period of time to convert the phosphorus in the water sample into orthophosphate,After cooling, a reducing agent and a color developer are added, and orthophosphate reacts with ammonium molybdate and potassium antimony tartrate before being reduced by ascorbic acidOriginally, a blue complex is generated and the absorbance is detected at a specific wavelength. According to Lambert Beer's law, the total phosphorus content in water isThere is a linear correlation between the amount and absorbance, which can be used to determine the total phosphorus concentration in water.

feature

lThe monitor is compact in size and easy to maintain on a daily basis;

lThe monitor adopts high-precision photoelectric measurement and detection technology, which is suitable for various complex water bodies;

lComes with three ranges (0-2mg/L), (0-10mg/L), and (0-20mg/L), meeting the needs of the vast majority of on-site applicationsMonitoring requirements for water quality. The range can also be expanded according to the actual situation on site;

lEquipped with measurement modes such as fixed-point, periodic, and maintenance, meeting the requirements for monitoring frequency on site;

lThe consumption of reagents is extremely low, greatly reducing operation and maintenance costs;

lMultiple communication methods such as 4-20mA, RS232/RS485, etc., meet the communication requirements of the monitoring instrument on site;
