T-721 Precise pH/DO Meter

การวัดค่า pH / DO อย่างแม่นยำในด้านเทคโนโลยีชีวภาพ การเพาะเลี้ยงสัตว์น้ำ,โรงไฟฟ้า ในการวิจัยทางวิทยาศาสตร์การควบคุมคุณภาพเทคโนโลยีชีวภาพและอุตสาหกรรมเคมี

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:
- 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, clock, wireless printing, function setup, smart self-diagnosis and other intelligent functions.
- English and Chinese operating system, humanized design with adjustable screen brightness.
- Auto recognition of standard pH buffer solutions and there are three kinds of standard buffers for option: USA series, NIST series and China series.
- Built-in big memory can store 1000 sets of test data which can be saved and transferred to USB 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 polarization.
- Combined diaphragm cap makes it extremely convenient to replace the sensitive membrane just by screwing the new cap to the electrode.
- DO measurement is polarographic and suggested to be used with our magnetic stirrer or other appropriate models chosen by customers.
- With standard Bluetooth module and support wireless Bluetooth printing to make operations much easier for users. Optional data transmission to PC and cell phone via Bluetooth.
- IP54 dustproof and waterproof housing.
