Kainafu Launches the KNF-1505Pro Portable Multi-Parameter Water Quality Analyzer for Field and Online Water Monitoring

Guangdong, China — Kainafu (KAFNO), a professional water quality monitoring instrument manufacturer based in Guangdong, China, is proud to announce the launch of its latest innovation: the KNF-1505Pro portable multi-parameter water quality analyzer. Engineered for demanding field environments and long-term unattended monitoring, this all-in-one analyzer redefines convenience, accuracy and durability for water quality professionals worldwide.

Modular Design, Maximum Flexibility

The KNF-1505Pro adopts an advanced all-in-one modular architecture. Every parameter sensor functions as an independent RS485 digital probe that connects to the main unit through watertight pluggable connectors. Calibration data is stored directly inside each probe, allowing operators to calibrate or replace sensors on-site within seconds — no factory return, no downtime. The main unit supports up to 6 pluggable probes simultaneously, together with one central automatic cleaning brush, and the probes and brush can be freely detached and recombined to match any monitoring task.

Comprehensive Parameter Coverage

This portable water quality analyzer supports real-time online monitoring of water temperature, pH, ORP, dissolved oxygen (DO), turbidity, chlorophyll, blue-green algae (cyanobacteria), electrical conductivity (salinity), oil in water, ammonia nitrogen and depth. Typical configurations cover:

• Dissolved oxygen: fluorescence method, 0–50 mg/L or 0–500% saturation
• Turbidity: 90° scattered light, 0–1000 NTU or 0–4000 NTU
• Conductivity / salinity / TDS: four-electrode, EC 0–200 mS/cm, salinity 0–175 ppt
• pH & ORP: glass / platinum electrode, ±0.02 pH and ±20 mV accuracy
• Chlorophyll & blue-green algae: fluorescence method with linearity R² > 0.999
• Oil in water: UV fluorescence method, 0–50 ppm or 0–150 ppm
• Ammonia nitrogen & depth: ion electrode and Pitot-type options, <0.1% F.S.

Built for Reliable Long-Term Operation

The KNF-1505Pro features a scheduled automatic wiping system that eliminates measurement errors caused by air bubbles and biofouling — ideal for weeks of unattended deployment. Smart diagnostics protect the system with voltage abnormality shutoff, communication fault alerts and wiper failure alerts. All probes are built with corrosion-resistant titanium alloy, POM and anti-fouling copper materials, and the complete system achieves an IP68 protection rating, with measurement depth up to 30 meters (20 meters for pH/ORP probes).

Intuitive Operation and Professional Data Management

The analyzer is equipped with a 7-inch touch-sensitive color display with bilingual Chinese and English menus, a 2-second data refresh cycle, and built-in storage for over 100,000 sets of data. A 15,000 mAh rechargeable battery supports all-day field campaigns, while RS485, USB and the included professional PC analysis software make data export, review and reporting effortless. The total weight is only 2.3 kg including the main unit and six sensors.

Wide Applications

The KNF-1505Pro portable multi-parameter water quality analyzer serves wastewater treatment plants, surface water monitoring stations, marine and groundwater monitoring programs, aquaculture farms, rivers and reservoir surveys, portable field inspection and laboratory analysis.
