TGH-SN Ammonia nitrogen (nessler's) water quality on-line automatic monitor

Description

Instrument is introduced

TGH - SN, NH3 - N water quality on-line automatic monitor using nessler's reagent colorimetric method, can according to the set even: long-term unmanned automatic renewal work, according to 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 product is suitable for the ammonia nitrogen in 0 ~ 5000 mg/L, within the scope of the wastewater of high calcium and magnesium ions, residual chlorine and turbidity may have interference on measurement.

The performance characteristics of
