Portable Dissolved Oxygen Meter- water quality sensor


Portable dissolved oxygen analyzer (determinator) is mainly used in laboratories, aquariums, aquatic product breeding, rice fields, swimming pools, etc. It is specially designed for the convenience of users to carry to the scene. The portable dissolved oxygen analyzer can be divided into two parts: the sensor and the electronic unit. The sensor adopts a tube-type coated dissolved oxygen electrode. The electronic unit is composed of high integrated circuits. The instrument uses a liquid crystal display, which can actually measure the dissolved oxygen, temperature, salt content and other values.

Probe type:

(1) Highly sensitive waterproof probe dissolved oxygen and temperature compensation combo/default shipping line length 3m (5m/10m optional).
(2) Automatic temperature compensation, the temperature will have a certain impact on the measurement, such as higher accuracy requirements, greater impact, temperature compensation can weaken this impact.
(3) High-definition large-screen display, intuitive data display, large viewing angle, clear handwriting, moderate character size, can clearly respond to backlight and high-light daytime use, quickly view values, and accurate data.


Portable dissolved oxygen detector is widely used in agriculture, industry (power plant, petrochemical, metallurgical Electronics), aquaculture, scientific research, biological fermentation, medical treatment, food and beverage, environmental water treatment and other fields.
