Product Description

KNF-1505Pro Portable Multi-Parameter Water Quality Analyzer

The kainafu KNF-1505Pro portable multi-parameter water quality analyzer features an all-in-one modular design. Each parameter sensor functions as an RS485 digital probe connected to the main body via a watertight pluggable connection. Calibration data is stored directly inside each probe, enabling easy field calibration and replacement.

It 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. The main unit supports up to 6 pluggable probes simultaneously.

KNF-1505Pro Portable Multi-Parameter Water Quality Analyzer 6 Pluggable RS485 Probes MODBUS IP68

Key Features

RS485 Output & Standard MODBUS Protocol: Seamless integration with data acquisition platforms and automated water quality monitoring stations.
Flexible Multi-Probe Support: Up to 6 pluggable probes with customizable configurations for DO, conductivity, turbidity, pH, ORP, chlorophyll, blue-green algae, oil in water, ammonia nitrogen, depth and more.
Automated Cleaning System: Scheduled automatic wiping eliminates measurement errors caused by air bubbles or biofouling, ideal for long-term unattended monitoring.
Field-Replaceable & Modular: All sensors can be replaced, calibrated and maintained on-site, offering maximum operational flexibility.
Smart Diagnostics: System protection and fault alarms include voltage abnormality shutoff, communication fault alert and wiper failure alert.
