Boqu Dog 2082X High Accuracy Industrial Dissolved Oxygen Meter

A specific energy wavelength is transmitted to a ruthenium compound in a sol-gel matrix. The ruthenium absorbs this energy, changing the electron's energy level. When the electron collapses back to its original state, it emits a photon with a different wavelength. This predictable and repeatable process is called 'fluorescing'.

We recommend checking calibration at least once a year. The sensor drifts less than one percent per year, ensuring long-term accuracy with minimal intervention.

Fluorescence technology has been used in the medical industry for decades. In the early 2000s, it was adapted for measuring dissolved oxygen in biological reactors. Key improvements included durability, cost-effectiveness, and easy-to-use packaging for the water treatment industry.

Yes, the sensor can be calibrated in the field. A simple calibration to a reference takes about a minute, allowing for convenient on-site maintenance.

The product is certified with RoHS, FCC, CE, and ISO9001, ensuring compliance with international standards for safety and quality management.
