Multiparameter Water Quality Analysers
In-situ and laboratory multiparameter analysers measuring 20+ water quality indicators for drinking water, surface water and wastewater compliance.
Most African water utilities operate without continuous water quality monitoring.
Most African water utilities lack continuous water quality monitoring, relying on weekly grab samples that miss contamination events between visits. YSI EXO and Hach multiparameter sondes measure pH, dissolved oxygen, conductivity, turbidity, nitrate, ammonium, chlorophyll and 15+ additional parameters simultaneously, providing real-time data to cloud dashboards and automated threshold alerts. Jos•Hansen supplies, installs and maintains the full YSI and Hach multiparameter range for water utilities, regulators and industrial water users across East Africa.
20+ parameters
A single YSI EXO sonde deployment measures pH, dissolved oxygen, conductivity, turbidity, nitrate, ammonium, chlorophyll, blue-green algae, rhodamine, temperature and depth simultaneously, replacing up to 20 separate single-parameter instruments and reducing field deployment time by 70%.
Real-time alerts
4G cellular telemetry transmits sonde data to cloud dashboards in real time, triggering SMS and email alerts when any parameter exceeds the configured threshold and enabling immediate response to contamination events before they reach consumers.
Lab confirmation
Hach benchtop and portable laboratory analysers provide certified method analysis for regulatory submissions, combining with field sonde data to create a complete monitoring chain from continuous screening to formal laboratory confirmation.
YSI EXO sondes measure 20+ parameters in a single deployment.
Fixed station deployments mount YSI EXO sondes in flow-through chambers connected via solar power and 4G cellular telemetry, providing continuous 15-minute interval data at water intake points, treatment plant inlets and distribution network monitoring points. Station data feeds into national water quality monitoring networks, triggering automated enforcement alerts when parameters exceed regulatory limits. Jos•Hansen provides turnkey station design, installation, commissioning and annual maintenance contracts.
Hach laboratory analysers produce certified method regulatory data.
Hach DR3900 and DR6000 spectrophotometers with pre-programmed EPA, APHA and ISO methods measure chemical oxygen demand, ammonia, nitrate, phosphate, heavy metals and 100+ additional parameters against certified analytical methods accepted by regulators. Portable Hach DR900 colorimeters and LDO optical DO sensors enable field verification of water quality at distribution network sample points and treatment process monitoring points without laboratory infrastructure. Jos•Hansen provides full method validation documentation and reference standard supply for regulatory submissions.
Fixed monitoring stations enable continuous compliance network operation.
Fixed station deployments mount YSI EXO sondes in flow-through chambers or direct in-stream configurations, connected via solar power and 4G cellular data transmission to provide continuous 15-minute interval data at water intake points, treatment plant inlets and distribution network monitoring points. Station data feeds into national water quality monitoring networks and triggers automated enforcement alerts when parameters exceed regulatory limits. Jos•Hansen provides turnkey station design, civil works specification, installation, commissioning and annual maintenance contracts.

Why Multiparameter.
WHO-compliant monitoring
All parameter ranges, calibration procedures and reporting formats are specified against WHO drinking water guidelines and national water quality standards.
Real-time contamination alerts
Continuous monitoring with configurable threshold alerts identifies contamination events within minutes, before affected water reaches consumers.
Full YSI and Hach support
Jos•Hansen provides factory-trained technical support, sensor calibration services, reagent supply and annual maintenance contracts for all installed instruments.
Reduced monitoring cost
Optical sensors eliminate reagent costs for key parameters, reducing ongoing monitoring cost versus wet chemistry methods while improving data continuity.
