I. Product Introduction

The intelligent ammonia nitrogen rapid analyzer is designed and manufactured with reference to the standards "HJ535-2009 Water quality — Determination of ammonia nitrogen — Nessler's reagent spectrophotometric method" and "Water quality — Determination of ammonia nitrogen — Salicylic acid spectrophotometric method". It mainly detects the ammonia nitrogen concentration of water quality and also provides intelligent data analysis, displaying data in charts and lists for clear analysis. It adopts a high-definition color LCD touch screen, an Android intelligent operating system, a Chinese display interface and a Chinese/English keyboard, with humanized operation for simpler use.

II. Applications

It is widely applicable to the detection of wastewater in various industries (industrial wastewater, municipal sewage, domestic sewage and surface water of rivers and lakes), and can meet various needs of different users. It can be used for monitoring industrial wastewater from the chemical, petroleum, coking, papermaking, metallurgy, brewing and pharmaceutical industries, as well as various domestic sewage.

III. Key Features

1	Brand-new Android 7.1.1 intelligent operating system with a humanized interface, faster operation and stronger stability.
2	8-inch LCD touch screen with a humanized interface for intuitive and simple readings.
3	Precision colorimetric cell design: a consistent light source eliminates result errors caused by light-source deviation, making detection more accurate.
4	The light source uses imported ultra-bright LEDs, and the brightness can be automatically adjusted and calibrated.
5	Supports 10 mm, 30 mm and 50 mm cuvette colorimetry and φ16 mm tube colorimetry, providing multiple options to ensure measurement accuracy.
6	Wireless communication: supports WIFI, RJ45 and mobile hotspot networking; test data can also be exported via a USB drive.
7	Multi-functional sample management: samples can be named in Chinese and English, facilitating sample recording and data storage.
8	The instrument permanently stores 8 million data sets; for convenient retrieval of large amounts of data, time-based search and arbitrary selection for analysis are supported.
9	Equipped with a supervisory cloud platform: data can be uploaded via LAN and the Internet, and can also be docked and uploaded to environmental supervision department platforms.
10	Built-in thermal line printer; the printed content is freely selectable (including QR code printing).
11	AC 220 V; an optional 6 Ah high-capacity rechargeable lithium battery is available for convenient outdoor mobile testing.
12	Built-in teaching demonstration video: users can watch the built-in operating video while performing experiments, making it easier to get started.
13	The product firmware can be upgraded later.
