Precise measurements of pH/DO in fields of biotechnology, aquaculture, power plant and environmental protection, and also more widely used in areas of education and scientific research. Main Features ?6.5 inch LCD screen which is intuitive and can show more parameters. Humanized design of operating interface makes operations simpler. ?Omron long lasting and light touch panel can be used more than 100,000 times. ?Auto calibration, auto temperature compensation, data storage, USB data export, clock, wireless printing, function setup, smart self-diagnosis and other intelligent functions. ?Built-in big memory can store 500 sets of test data which can be saved and transferred to USB flash drive and opened with Excel, very easy and convenient for edit. ? Auto recognition of standard pH buffer solutions and there are three kinds of standard buffer for option: USA series, NIST series and China series. ?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 minutes for polarization. ?Combined diaphragm cap makes it extremely convenient to replace the sensitive membrane just by screwing the new cap to the electrode. ?Optional Bluetooth block and support Bluetooth printing to make operations much easier for users. Optional data transmission to cell phone via Bluetooth. ?Smart judge of electrode status to ensure accurate use for operators. ?IP54 waterproof and dustproof.
