Total nitrogen analyzer GM-541

Ø Introduction

This instrument features a liquid crystal display, a separate design for the digester and host, built-in curves, a built-in printer, and a USB interface for uploading data. It is widely used in environmental monitoring, sewage treatment, large, medium, and small water plants, industrial and mining enterprises, domestic or industrial water use, universities, research institutions, and other departments.

Ø Main Features

l Using imported high-performance, long-life (100000 hours), high brightness light source, coupled with a highly stable optical system, with good accuracy and repeatability.

l The temperature digestion is completed using an independent digestion device, with PID automatic temperature control and high temperature control accuracy.

l Large screen LCD display, Chinese character menu style operation, convenient and intuitive.

l The separation of high-temperature digestion and the main unit avoids the impact of high-temperature components on the optical system.

l It can store 10 working curves and 99 historical records without losing them during power outages.

l Equipped with a USB interface, data can be transferred to a computer.

l Equipped with printing function, it can immediately print or query test records for printing.
