PRODUCT FEATURES
- 7 inch color capacitive screen with high resolution (1024*600) and sensitivity, which can show more parameters, more intuitive, and simpler to read data.
- Auto calibration, auto temperature compensation, data storage, USB data export, wireless printing, function setup, smart self-diagnosis and other intelligent functions.
- Built-in memory can store 300 sets of test data which can be saved and transferred to USB flash drive and opened with Excel, very easy and convenient for edit.
- DO mode has functions of ATC, auto salinity compensation and auto pressure compensation.
- New structure polarographic DO electrode can measure temperature, salinity, and dissolved oxygen simultaneously, equipped with special DO electrode calibration sleeve, only need 3~5 min for polarozation.
- Combined diaphragm cap makes it extremely convenient to replace the sensitive membrane just by screwing the new cap to the electrode
- Auto recognition of standard pH buffers. There are three series of standard buffer solutions for option: USA, NIST, and China series.
- IP54 dustproof and waterproof housing.
