Industrial Water Quality Sensor Manufacturer — digital, self-cleaning, tender-ready
Online and portable sensors for DO, pH, COD, turbidity, ammonium, conductivity and multiparameter monitoring — reagent-free optics, native RS485 Modbus, CE/ISO certified, built for municipal, industrial, environmental and drinking-water systems.
Latest engineering case studies
From water-matrix review to field-ready monitoring
Recent customer projects show how sensor selection changes when the water matrix, measurement objective, installation and validation method are reviewed together.
Compressor condensate oil monitoring for Emerson
Reviewing the lubricant chemistry, separator outlet and EPA Method 1664 objective changed the selection from a trace PAH probe to a matrix-matched OIW monitoring channel. The order is placed and field validation is in progress.
Two-channel sensor evaluation for an OEM system
A North American water-treatment OEM evaluated WS-OM-OIW-15C for emulsified lubricating oil and WS-OM-COD-11DE for UV254-derived COD trending, with independent controllers and site-specific validation.
Beyond ultra-low turbidity at Lisbon Oceanarium
When turbidity was already exceptionally low, the project reframed the remaining clarity question through complementary CDOM and tryptophan-fluorescence trends, marine-compatible materials and Modbus integration.
