product key technologies
This product is a pen-type dissolved oxygen controller centered on portability, specially designed to allow users to perform fast and accurate measurements directly on site. Featuring an overall compact structure, the instrument consists of two core parts: a high-performance sensing assembly and a highly integrated electronic module.
The sensing assembly adopts a membrane probe based on the polarographic principle, with the advantages of fast response and high stability, enabling reliable detection of dissolved oxygen content in water bodies. The electronic module applies a highly integrated circuit system, which ensures signal processing accuracy while effectively reducing power consumption and overall volume, realizing true one-hand operation and easy portability. Equipped with a backlit dot-matrix LCD screen, the device can clearly display measurement data even in low-light on-site environments. The screen supports simultaneous display of dissolved oxygen concentration and temperature readings, greatly improving on-site testing efficiency.
This pen-type dissolved oxygen controller is widely applied in aquaculture, environmental monitoring, sewage treatment and industrial process control, serving as an ideal tool for professional technicians to quickly detect dissolved oxygen concentration on site.
Feature
- It features automatic correction for water temperature variation and delivers rapid detection response.
- Adopting a lightweight overall design, the instrument is easy to carry for field operations.
- It comes with a self-produced polarographic membrane dissolved oxygen probe supplied by our company.
