HM-SNH Handheld Ammonia Nitrogen Detector

Product Introduction

The HM-SNH is a compact handheld ammonia nitrogen detector manufactured by HM Instruments, designed for swift and accurate water quality monitoring across versatile industrial and environmental environments. Pairing with rapid chromogenic reagents, the device provides rapid, simple, accurate, and stable quantitative determination of ammonia nitrogen concentrations in diverse aqueous systems. Operators can routinely rely on the HM-SNH handheld ammonia nitrogen detector for environmental compliance and process verification.

Configured with multiple internal solid-state light sources aligned with specific analytical wavelengths, the HM-SNH supports both Nessler reagent spectrophotometry compliant with standard HJ 535-2009 and optional salicylic acid spectrophotometry compliant with standard HJ 536-2009. The instrument incorporates an intelligent Android operating system alongside a responsive 3.5-inch high-definition color touchscreen, replacing cumbersome push-button interfaces with intuitive guided procedures that require no prior technical training. Weighing only 325 grams and equipped with an internal 5600 mAh rechargeable lithium battery supporting up to 8 hours of continuous field operation, it delivers laboratory-grade photometric precision directly to sampling outfalls, aquaculture ponds, and water treatment basins.

Furthermore, integrated Type-C, WiFi, and Bluetooth connectivity allow immediate wireless synchronization with cloud supervisory platforms, assisting technical personnel in tracking long-term water quality patterns and maintaining verifiable digital compliance records.

Applications

• Industrial Wastewater Surveillance: Monitoring effluent discharge from chemical plants, electroplating works, and food manufacturing facilities
• Aquaculture Water Management: Daily monitoring of ammonia nitrogen levels in fish hatcheries, shrimp ponds, and recirculating aquaculture systems
