Features
Precision Water Quality Monitoring
The NP-1806 digital PH controller delivers laboratory-grade accuracy (±0.01pH) with its high-sensitivity glass electrode sensor, ensuring reliable real-time water quality analysis. The corrosion-resistant titanium alloy body and triple-junction reference system extend lifespan in harsh environments.
Industrial-Grade Durability
Built with IP68 waterproof housing and a reinforced cable design, this unit withstands continuous submersion, high-pressure cleaning, and extreme temperatures (-5°C to 60°C). The scratch-resistant LCD displays readings clearly under direct sunlight.
Smart Automation Integration
Features automatic temperature compensation (ATC) and 4-20mA output for seamless connection to PLC systems, ideal for aquaculture farms, wastewater treatment plants, and hydroponic agriculture. Calibration reminders prevent drift errors.
User-Centric Engineering
Tool-free sensor replacement and one-button calibration save maintenance time. Includes a dual-layer protective cap with KCl storage solution to keep the electrode hydrated during transport or storage.
Global Compliance Ready
Meets ISO 9001 and CE standards, compatible with international water safety protocols. Ships with pre-installed ISO calibration certificates for immediate deployment.
Bulk Order Advantage
Direct-from-factory pricing with MOQ flexibility. Customizable probe lengths (available 1m/3m/5m) and OEM branding options for large-scale procurement projects.
