S-623 Precise Conductivity/DO Meter

Word:[Big][Middle][Small] QR Code 2018/7/16     Viewed:    

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.

● Meet GLP norms, with 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: Europe & USA series and China series.

●Adopt advanced conductivity measurement technology, one point calibration of conductivity electrode with constant K=1 can meet the measuring accuracy requirements for test 0.5μ 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.

●With standard Bluetooth block and support wireless Bluetooth printing to make operations much easier for users. Optional data transmission to PC and cell phone via wireless Bluetooth.

● IP54 dustproof and waterproof housing
