Yantai dongrun Instrument Co., Ltd. was founded in 1998, specializes in manufacturing online water quality analysis equipment, material level meters, pressure gauges, flow meters, special temperature gauges and

laboratory analysis equipment. Our company cooperate with the Chinese Academy of Sciences to build a water analysis laboratory, and the main products are TOC analyzer, ammonia analyzer, fluorescence oxygen analyzer, etc. We have passed the ISO9001 certification and has a professional R & D team, providing technical support to meet customer demand, particularly in the anti-corrosion, our company has a unique technology to meet different conditions of corrosion requirements.

II Product Introduction   

FDO-99C Economical Fluorescence Dissolved Oxygen Analyzer

FDO-99C series fluorescence dissolved oxygen analyzer is designed for water environment monitoring, aquaculture and other applications . Based on the principle of fluorescence quenching and integrated automatic temperature compensation, automatic air pressure compensation function, the measurement results are more accurate and real-time performance is better.It is especially suitable for marine monitoring, aquaculture and other pressure sensitive and pressure changes on the larger occasions.

Feature 

High-performance configurations: digital sensors, intelligent display, operation interface, built-in RTC clock;

Multi-parameter measurement: simultaneous detection of dissolved oxygen, water temperature, ambient temperature, atmospheric pressure;

Measurement is more accurate:three-dimensional calibration before delivery.Automatic pressure, temperature compensation when it is used; 

Easier to maintain: Calibration-free within a year, no vulnerable device, only need regular cleaning probe;

Meet the demand of a variety of applications: Available in various output modes
