BOQU - Model BQ401 -Portable Multi-parameter Analyzer and Sensor
This instrument can measure temperature, optical dissolved oxygen, fiber optic turbidity, four-electrode conductivity, pH, salinity, etc. The BQ401 multi-parameter handheld probe can support up to 4 types of probe measurements. When connected to the instrument, these data can be automatically identified. This meter is equipped with a backlight display and operation keyboard. It has comprehensive functions and simple operation. The interface is simple. It can also realize measurement data storage, sensor calibration and other functions at the same time, and it can export USB data to achieve more high-end functions. The pursuit of high cost performance is our consistent pursuit.
The dissolved oxygen sensor included in the product uses the world`s leading fluorescence lifetime technology, which is based on the principle of quenching active fluorescence by specific substances in physics. The significant advantage of this fluorescence method for measuring dissolved oxygen is that it does not consume oxygen during the measurement process, so there is no flow rate limitation, at the same time, no preheating, no electrolyte, maintenance and frequent calibration, and the response time of the optical dissolved oxygen probe is as low as 30 Seconds, making dissolved oxygen measurement more accurate, more stable, faster and more convenient.
