S-621 Precise pH/DO Meter

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.
