P-521 Portable pH/Dissolved Oxygen Meter by Peak Instruments
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.
