Functional Features
High-performance, ultra-low-power 16-bit microcontroller with high-capacity rechargeable lithium battery to ensure extended instrument runtime.
Adopts internationally leading fluorescence technology, which does not consume oxygen during measurement, is not affected by test solution contamination, and has no flow rate limitations.
No need to replace membranes or electrolytes, unaffected by flow rate, stirring environment, or chemical substances, strong anti-interference ability, and stable measurement.
Large LCD screen with Chinese and English menu display for convenient and intuitive operation.
Supports measurement of dissolved oxygen concentration, dissolved oxygen saturation, and temperature values.
High stability, no frequent calibration (no calibration needed for routine detection) or sensor cap replacement, maintenance-free and less frequent calibration.
Automatic temperature and pressure compensation by the instrument, plug-and-play.
Salinity compensation function: capable of testing dissolved oxygen in seawater and various salt solutions.
The probe's response time is as low as 30 seconds, making dissolved oxygen measurement faster and more convenient.
Data protection against power loss, with storage capacity for 300 data sets.
Type-C port for data transfer to a computer.
The instrument has good corrosion resistance, waterproofing, and dustproofing.
