LH-T3NHN Ammonia Nitrogen Rapid Tester
Product Introduction
The LH-T3NHN Ammonia Nitrogen Rapid Tester is designed for fast determination of ammonia nitrogen (NH₃-N) in water. It complies with the requirements of HJ 535-2009, Water Quality—Determination of Ammonia Nitrogen—Nessler's Reagent Spectrophotometry.
With a segmented measurement range of 0–160 mg/L, the instrument provides direct concentration readings and supports two colorimetric modes: φ16 mm colorimetric tubes and 10 mm cuvettes. Its 3.5-inch high-definition color display, multiple calibration curves, and 5,000-record storage capacity make it a practical solution for routine water quality testing.

Performance Features
• Fast ammonia nitrogen measurement: Designed for rapid NH₃-N testing with direct concentration readings and simple operation.
•  Dual colorimetric modes: Compatible with φ16 mm colorimetric tubes and 10 mm cuvettes for flexible sample measurement.
•   Multiple calibration options: Provides three measurement modes and 15 selectable calibration curves. Working curves support calibration at commonly used points.
•  Wide measurement range: Covers 0–160 mg/L in segmented ranges for different water testing requirements.
•  High-definition color display: Features a 3.5-inch OLED color screen with a clear, intuitive dial-style user interface.
•  Long-life optical system: Uses a cold light source and narrow-band interference technology, with a stated light source life of up to 100,000 hours.
•   Large data storage capacity: Stores up to 5,000 measurement records, including test time and measured concentration, for on-device review and comparison.
•  Compact and lightweight: Weighs only 0.85 kg, making it convenient for laboratory and field testing.

Working Principle
The LH-T3NHN uses the Nessler reagent spectrophotometric method specified in HJ 535-2009. Under alkaline conditions, ammonia nitrogen reacts with Nessler reagent to produce a colored compound. The instrument measures the absorbance of the resulting solution using its optical system and calculates the ammonia nitrogen concentration based on the selected calibration curve.
The cold light source and narrow-band interference technology provide a stable optical signal for colorimetric measurement. Users can select the appropriate measurement mode and calibration curve, then read the concentration directly from the display.
