DO820 portable dissolved oxygen analyzer
DO820 portable dissolved oxygen analyzer
Product details
  • The DO820 portable dissolved oxygen analyzer is suitable for measuring the concentration or saturation of oxygen dissolved in water

    Automatic calibration:
    The instrument can perform 2-point automatic calibration with anaerobic solution. During calibration, the instrument has automatic recognition function. If you use anaerobic solution with large deviation for calibration, the instrument will automatically prompt an error and stop calibration.
    Automatic temperature compensation:
    Due to the influence of temperature on the solubility and diffusion rate of oxygen, the instrument needs to have temperature compensation function when measuring dissolved oxygen. It has automatic temperature compensation and measurement functions. When the dissolved oxygen sensor is connected to the host, the instrument will automatically enter temperature compensation mode.
    Can set salinity and atmospheric pressure:
    The salt dissolved in water will limit the oxygen content soluble in water, and the relationship between oxygen concentration and partial pressure varies with the salinity of the sample. The salinity value can be set within the range of 0-35g/L to correct measurement errors caused by ion concentration. Meanwhile, the instrument can set atmospheric pressure values within the range of 450 to 850 millimeters of mercury.
    Automatic power monitoring:
    Built in power monitoring chip, when the battery level is low, the battery icon will automatically turn off to prompt you to replace the power supply.
    Data locking function:
    When measuring samples, in order to easily read the measurement results, you need to keep the values for a period of time. The data locking function provided provides you with convenience. When in use, press the HOLD key to automatically lock the current displayed value of the instrument. Press the key again to return the instrument to measurement mode.
    Automatic message prompt:
    It has an operation information prompt function. When you enter a setting or measurement, the information bar will help you understand what operations the instrument can perform and how to operate it in the current state. It is equivalent to the operation steps in the user manual. Through the guidance of the information bar, you can easily complete a certain setting or measurement task.
    Data storage and output:
    The instrument has 48 sets of data storage functions. Press the SAVE key during measurement, and the instrument will automatically save the current measurement value and mark the data with serial number, date, time, and other information for future reference. The data stored in the instrument can be sent to personal computers through a USB data cable
    Brain, you can save measurement values or print test reports through software.
    Instrument configuration:
    1 DO100 dissolved oxygen electrode, 1 bottle of dissolved oxygen filling solution, electrode membrane cap
    2, 1 9V battery.
