Portable Type
Suitable for industrial and mining factories, power plant, aquaculture and environmental protection, especially for outdoor purposes.
Main Features
●Large LCD screen with controllable white backlight.
●Humanized designs like rack and skid proof shell make it more convenient for users.
●Built-in microprocessor chip with functions of auto calibration, auto temperature compensation, data storage, function setup, self-diagnosis, auto power off, low voltage display.
●Double-parameter and equipped with pH electrode and DO electrode, can recognize electrode automatically.
●Auto recognition of standard pH buffers and there are three series of standard buffers for option: USA, NIST and China.
●Able to set pH measurement modes of high purity water and pure water with ammonia.
●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 and equipped with special DO electrode calibration sleeve, only need 3~5 minutes for polarization.
●IP57 and there is optional carrying case.
