For high-precision measurements of the conductivity/DO in laboratory. Widely used in the fields of biotechnology, aquaculture, power plants and environmental protection. 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 eight kinds of standard conductivity solution and there are two series of standard solution for option: USA series and China series. ?Adopt advanced conductivity measurement technology, one point calibration of conductivity electrode can meet the measuring accuracy requirements for test 0.5? S/cm ~ 200mS/cm. ?Able to switch between conductivity, TDS, salinity and resistivity. Multinomial calculation for TDS and salinity to ensure the conversion precision of the full scale. ?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 module and support wireless Bluetooth printing to make operations much easier for users. Optional data transmission to cell phone via wireless Bluetooth. ? IP54 dustproof and waterproof housing
