The handheld ammonia nitrogen analyzer is primarily used to measure ammonia nitrogen levels in water bodies. The device is equipped with multiple light sources corresponding to different detection wavelengths, enabling simultaneous compliance with both the Nessler reagent method and the salicylic acid method for measuring ammonia nitrogen levels in water bodies. The Nessler reagent method references the environmental standard HJ 535-2009 “Water Quality - Determination of Ammonia Nitrogen - Nessler's Reagent Spectrophotometric Method,” while the salicylic acid method follows the environmental standard HJ 536-2009 “Water Quality - Determination of Ammonia Nitrogen - Salicylic Acid Spectrophotometric Method.” The instrument is equipped with a high-resolution color LCD touchscreen display, an Android smart operating system, a Chinese language interface, and a Chinese/English keyboard, offering user-friendly operation for easier use.
The handheld ammonia nitrogen detector is widely used in emergency monitoring, industrial wastewater, domestic sewage, wastewater treatment, pharmaceuticals and chemicals, food, beverages, textile dyeing, electroplating, papermaking, petroleum and metallurgy, river management, research institutions, and educational institutions.
Android smart system for more convenient and efficient operation.
Configured with a cloud monitoring platform, detection results can be directly transmitted wirelessly to the platform for long-term and short-term water quality analysis and management assistance.
Built-in operating procedures, simple operation, no training required, ready to use.
Faster detection speed with on-site data reading.
Portable, compact size, lightweight, ideal for outdoor testing.
Compact and aesthetically pleasing design, stable operation with minimal maintenance, offering excellent cost-effectiveness.
Features an imported cold light source with stable optical performance and a lifespan of up to 100,000 hours.
AC/DC compatible, with built-in rechargeable lithium battery, environmentally friendly and durable, supporting continuous indoor and outdoor operation.
