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

Description

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
