Word:[Big][Middle][Small] QR Code 2018/11/5     Viewed:    

Suitable for high precision pH/conductivity measurements in scientific research, quality control, biotechnology and fine chemistry industry.

Main Features:

●7 inch colored capacitive screen with high resolution (1024*600) and sensitivity, which can show more parameters, more intuitive and simpler to read data.

● 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.

●English and Chinese operating system, humanized design with adjustable screen brightness.

●Built-in big memory can store 1000 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 8 kinds of standard conductivity solutions and there are two series of standard solutions for option: Europe & USA series and China series.

●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 wireless Bluetooth.

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.

Auto recognition of standard pH buffers. There are three series of standard buffer solutions for option: Europe & USA, NIST and China series.

●Smart judge of electrode status to ensure accurate use for operators.

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

●IP54 dustproof and waterproof housing.
