SLDW1140 Ion-Selective Electrode Nitrate Nitrogen Analyzer: Your Trusted Partner for Precision Water Quality Monitoring
Dec 19, 2025| SLDW1140 Ion-Selective Electrode Nitrate Nitrogen Analyzer: Your Trusted Partner for Precision Water Quality Monitoring
In the global pursuit of environmental protection and water resource management, accurate nitrate nitrogen detection has become a critical demand for industries, municipal water treatment, and agricultural irrigation. Introducing the **SLDW1140 Series Ion-Selective Electrode Nitrate Nitrogen Analyzer** - a high-performance solution designed to deliver reliable, efficient, and precise monitoring, tailored for international markets with global applicability.
Cutting-Edge Technology, Unmatched Accuracy
Powered by advanced ion-selective electrode technology, the SLDW1140 features an ion-permeable membrane composite sensor that detects the redox potential of target ions with exceptional specificity. Combined with a reference sensor, it converts millivolt-level voltage signals into precise ion concentration values, ensuring trustworthy results every time. With a measuring range of **0.5~1000mg/L for nitrate nitrogen (No3-N)**, pH 0~14, and temperature 0~50℃ (water sample: 0~40℃, non-freezing), it covers most industrial and environmental monitoring scenarios. Boasting an accuracy of ≤±10% or ±0.2mg/L (whichever is larger) and a resolution of 0.1mg/L for nitrate nitrogen, it meets strict international quality standards, helping you stay compliant with global environmental regulations.
Robust Design, Adaptable to Harsh Conditions
Built for durability, the SLDW1140 thrives in challenging work environments. The transmitter (270x205x100mm) is crafted from ABS+PC, while the sensor (Φ58×341mm) uses 316L stainless steel and POM - materials resistant to corrosion and wear. With an IP65 protection rating for the transmitter and IP68 for the sensor, it withstands dust, moisture, and even submersion, making it ideal for both indoor and outdoor installations. Supporting dual power supply (85-265VAC/50/60Hz or 24VDC±10%), it adapts seamlessly to different regional power grids worldwide. The R5/4 inch round chain external thread installation design ensures quick and stable setup, saving time on on-site deployment.
User-Friendly Operation, Intelligent Data Management
Efficiency meets convenience with the SLDW1140's user-centric features. Factory-calibrated for nitrate nitrogen and pH, it requires no frequent recalibration (supports on-site calibration if needed), reducing maintenance hassle. The LCD screen displays real-time measurements, date, time, and historical trend lines, with optional Chinese/English menus to cater to global users. Equipped with automatic data storage and power-off protection, it preserves up to **10 years of historical data** - perfect for trend analysis and audit trails. With 2 isolated 4~20mA analog outputs, 3 programmable relays (2A/250VAC), and optional MODBUS RS485/Profibus DP digital interfaces, it integrates effortlessly with your existing automation systems.
