NigeriaEnglish ISO 7027 90° scatter method, IP68 stainless housing, RS-485 digital output with direct networking — covering drinking water, wastewater and surface water
RS-485 digital output \u00b7 Modbus RTU \u00b7 IP68 \u00b7 ISO 7027
Complies with ISO 7027 / EPA 180.1; 860 nm near-infrared light source eliminates color interference
The ZS-D160's automatic wiper periodically cleans the optical window, extending maintenance-free intervals to 6 months
An embedded PT1000 sensor continuously compensates the scatter signal for temperature \u2014 \u00b12% FS across the range
Standard Modbus RTU protocol connects directly to PLC / DCS / SCADA \u2014 no secondary transmitter needed
316L stainless steel + sapphire optical window for long-term submersion, corrosion and pressure resistance
Turbidity (NTU) / suspended solids (SS, mg/L) / sludge concentration (MLSS, g/L) \u2014 one instrument, many jobs
Influent/effluent SS monitoring, aeration basin MLSS control, secondary clarifier sludge blanket
Real-time turbidity monitoring of raw, settled, filtered and finished water per GB 5749
Continuous turbidity/SS measurement in rivers, lakes and reservoirs; supports long-term buoy deployments
Cooling tower and exchanger inlet SS monitoring prevents scaling and microbiological growth
CIP solution turbidity monitoring, process water clarity checks, pre-filling water verification
Online transparency/SS monitoring of culture water for feeding and water-exchange decisions
