Why Choose Qualitest for Your Online Water Quality Analyzer Needs
Qualitest is a globally recognized supplier of advanced water-quality, environmental, and analytical instruments, serving customers worldwide with one of the most comprehensive Online Water Quality Analyzer portfolios available — engineered for the rigorous accuracy, durability, and regulatory-compliance demands of modern water-management operations.
Four-Platform Portfolio — One Trusted Source
From the QT-W9F Multi-Parameter Water Quality Tester for water plants and aquaculture, through the QT-W226G manhole/confined-space monitoring system and the QT-W227F floating surface-water station, to the flagship all-inclusive Outdoor Water Quality Monitoring Station — Qualitest offers a coordinated portfolio that matches every installation environment, parameter scope, and regulatory requirement.
Multi-Parameter Coverage — pH to Heavy Metals
Qualitest online water analyzers continuously monitor the complete water-quality parameter spectrum — pH, conductivity, ORP, TDS, dissolved oxygen, turbidity, COD, BOD, TOC, TSS, ammonia nitrogen, total phosphorus, total nitrogen, residual chlorine, nitrate, temperature, and heavy metals — making each platform a single-source solution for diverse regulatory and operational requirements.
EU RoHS-Certified Sensors & No-Reagent Operation
The QT-W9F sensors (pH, dissolved oxygen, residual chlorine, conductivity, turbidity, temperature) are EU RoHS certified, demonstrating compliance with the European Restriction of Hazardous Substances directive. Combined with reagent-free operation across the QT-W9F and QT-W227F platforms (eliminating reagent consumption, secondary pollution, and waste-liquid handling), Qualitest delivers genuinely sustainable continuous monitoring.
Flexible Sensor Combinations & Easy Maintenance
Every Qualitest analyzer supports flexible sensor combinations — meaning a customer can configure any subset of parameters per installation site and reconfigure later as regulatory requirements evolve. Combined with simplified installation procedures, automatic temperature compensation across sensors, and modular design supporting quick sensor replacement, total cost of ownership across multi-year deployment is dramatically reduced.
Full SCADA & Industrial-System Integration
Multiple output options across the portfolio — 4-20 mA analog, RS-485 serial, MODBUS-RTU industrial protocol, GPRS cellular, and Ethernet — ensure seamless integration with municipal SCADA systems, plant DCS architectures, regulatory data-reporting platforms, and remote-monitoring networks. Real-time data flows directly to operators, dispatchers, regulators, and brand-owner specification teams worldwide.
Complete Outdoor Station Infrastructure
The Outdoor Water Quality Monitoring Station includes everything required for permanent outdoor deployment — chassis, water tank, self-priming pump, analog module, host, air conditioner, touchscreen, PLC, relays, signal lights, air openings, solenoid valves, water-intake pumps, and back-cleaning pumps. The all-inclusive cabinet with power distribution and surge switches meets the installation and operation needs of outdoor pumps, pipelines, transmitters, and test instruments.
Cost-Effective Value & Global Support
Qualitest delivers premium online water-quality monitoring performance at a transparent, competitive price point — backed by global service, training, calibration support, sensor replacements, and stocked accessories worldwide. With offices and authorized partners across the world, expert installation, operator training, and ongoing service are always within reach.
