Product Description

DO700 portable micro-dissolved oxygen analyzer

Product overview:
DO700 portable trace dissolved oxygen analyzer is a high-performance portable measuring instrument, used to measure the concentration of oxygen content in aqueous solution, especially for the detection of low concentration dissolved oxygen in ultra-pure water.It can be widely used in many industries such as electric power, petrochemical, steel and so on.
The product is mainly composed of host (liquid crystal display, circuit board, etc.), sensor (polarographic electrode), circulation pool and cable. When in use, the sample water is introduced into the measuring device through the sample feeding tube (lower port).
The secondary instrument adopts full metal shell, which is strong, waterproof and anticorrosive. More importantly, it has good shielding effect and strong anti-interference ability.The polarographic oxygen sensor which can be used to detect low concentration dissolved oxygen in ultrapure water is adopted to ensure the accuracy of the instrument.Delicate design and simple flow path make the maintenance of the instrument very small, and ensure the stability of the measurement signal, and strong, reliable.


Features:

1. The polarographic microvolume dissolved oxygen detection electrode is suitable for the detection of low concentration oxygen content with the measurement accuracy of microgram.
2. The instrument adopts integrated structure design, small size, light weight, easy to carry and put.
3. The measuring part adopts the whole waterproof structure design, the overall waterproof effect reaches IP65, a variety of installation and placement, making the measurement more convenient.
4. High brightness OLED lattice LCD display, can read data clearly in a certain distance.
5. Automatic USB interface, not only can be charged, but also can be connected to the bit machine for reading data.
