DO-810 dissolved oxygen meter (fluorescence method)
Introduction: The DO-810 portable dissolved oxygen meter is measured and controlled by an ultra-low-power single-chip microcomputer, and measured by a fluorescence method. It has the advantages of stability and reliability, simple and convenient operation; the instrument can indicate the measurement results in two dissolved oxygen content units, namely oxygen concentration (mg/L) and oxygen saturation percentage (%). The temperature (°C) of the medium is measured and displayed. This instrument has the functions of computer program-controlled calibration, automatic temperature compensation, salinity correction and atmospheric pressure adjustment, and is suitable for the measurement of oxygen content in aqueous solutions in various industries. Applicable fields: Laboratory testing in various industries, sewage treatment, colleges and universities, scientific research units. Features: 1. High-performance ultra-low power consumption 16-bit single-chip microcomputer with high-capacity rechargeable lithium battery. 2. LCD large-screen LCD Chinese menu display, easy to operate and intuitive. 3. Good anti-corrosion, waterproof and dust-proof performance. 4. One or two point calibration, saturation percentage calibration. 5. Temperature compensation. 6. The salinity coefficient and atmospheric pressure can be set. 7. The electrode has a long service life. 8. Can store 300 sets of data. 9. Data power failure protection function, with Type-c port, can be connected to a computer to transmit data.
