Portable fluorescent dissolved oxygen analyzer high-precision water quality detection equipment

The portable high-precision fluorescence dissolved oxygen analyzer is developed and produced by Zhongke Zhigan (Nanjing) Environmental Technology Co., Ltd. Based on the principle of excellent fluorescence quenching, it is a handheld dissolved oxygen detection device suitable for aquaculture, sewage treatment, laboratory research, and environmental monitoring scenarios. It has the advantages of portability, accuracy, stability, and easy operation, and can meet the dual needs of field operations and laboratory precision measurement.

The core of the instrument adopts fluorescence quenching technology, which accurately calculates the dissolved oxygen concentration by detecting the phase difference change of the fluorescent membrane signal. The built-in temperature sensor can automatically complete temperature compensation without the need for manual input of temperature values, making the operation more convenient. The measurement range is 0.00~20.00mg/L, the resolution is 0.01mg/L, the T90 response time is ≤ 40s, the dissolved oxygen accuracy is ± 0.2mg/L, and the temperature accuracy is ± 0.5 ℃. The measurement is fast and the data is reliable. At the same time, it has excellent anti-interference ability, can resist electromagnetic field and chemical interference, and can still work stably in complex water environments.

The operation adopts a 9-key convenient design and a segmented LCD display screen, which can synchronously display key information such as dissolved oxygen concentration, temperature, saturation, power, time, etc. Support functions such as one click measurement, single/two-point calibration, salinity compensation, air pressure compensation, historical data storage and retrieval, timed measurement, and switching between Chinese and English. Calibration is flexible, settings are intuitive, and ordinary personnel can quickly get started. IP68 protection level probe with corrosion-resistant shell, sturdy and durable; The host is compact and lightweight, easy to carry, and suitable for long-term outdoor operations.

The instrument is powered by rechargeable lithium batteries and equipped with energy-saving settings such as automatic backlight off and automatic shutdown, providing longer battery life. Supports RS485 communication and MODBUS protocol, can be connected to data acquisition systems, and meets the requirements of intelligent monitoring; The probe fluorescent film body supports replacement, effectively reducing usage costs. Daily maintenance is simple. The electrodes can be cleaned with a soft cloth or sponge soaked in water. Storage should be kept away from light and lightsignificant differencesTemperature.

After sales provide a one-year warranty for the entire machine, free maintenance for non-human faults, and online guidance, operation videos, and customer service support. ESEQ-200, with its precise performance, convenient operation, and reliable quality, has become the preferred equipment for rapid detection of dissolved oxygen in water environments, providing efficient data support for aquaculture control, sewage treatment operation and maintenance, environmental monitoring, and scientific research experiments.
