1720E Low Range Online Turbidity

Typical applications:
Line turbidity meter may be used in different parts of the filter means to measure raw water or purified water turbidity. 1720E Low Range Hach turbidimeter can be applied in-line filter before the water plant, after filtration, sedimentation and finished water turbidity monitoring; municipal pipe network water quality monitoring; industrial process water quality monitoring, cooling water, activated carbon filters the water, membrane filtration water and so on.

● Set within the online turbidimeter patent bubble Elimination System
● cleaning and maintenance is very simple; calibrated once a month
● Online turbidimeter reproducible from sample flow rate and pressure effects
● The 0-point calibration method with 20NTU - Recommended correction method
● You can also do a single-point calibration by comparing: (1-40NTU range of optional point)
● Online Turbidity measurement units: NTU; while a variety of auxiliary units of measurement display: FTU, TE / F, mg / L
● USEPA (United States Environmental Protection Agency) approved methods
