TGH-STP Automatic on-line monitor of total phosphorus water quality


Instrument is introduced
TGH - STP total phosphorus of water quality on-line automatic monitor by using phosphorus molybdenum blue colorimetric method can according to the set unattended automatic continuous work for a long time, depending on the complexity of the working condition of field test, optional corresponding pretreatment system, to ensure that the test results are accurate and reliable process, fully meet the requirements of different occasions. This method is applicable to wastewater with total phosphorus within the range of 0~500mg/L. Most common ions do not interfere with the determination, but for some samples containing a large amount of organic matter, the measurement results may be low.
The performance characteristics of
The principle of instrument testing adopts the national standard method, and the testing process fully conforms to the relevant standards of the industry
Simple maintenance and low running cost
Convenient maintenance, low failure rate and long service life
Automatic calibration and cleaning
Data storage records are never lost; Energy saving, no secondary pollution
Automatic alarm, automatic diagnosis, automatic elimination of residual reactants and automatic recovery
