1.      Tính năng kỹ thuật:

-          5 languages display (English,  Japanese, Russian,  Spanish, Portuguese)

-          Multiple sensors allow for the measurement of 11 paramenters simultaneously.

-          (pH, pH (mV), ORP, DO, COND, Salinity, TDS, Seawater, Specific Gravity, Temperature, Turbidity, Water depth)

-          Turbidity sensor U-53 conforms to US EPA method 180.1 Precision has been improved over conventional instruments. The Model U-53 high precision field replaceable sensor with wiper has a resolution of 0.01 NTU.

-          Turbidity sensor of U-54 conforms to EN ISO 7027. The model U-54 has a resolution of 0.01 NTU.

-          Improved stability of the dissolved oxygen sensor has been achieved with a new 3 electrode design for fast response and polarographic sensor for ease of maintenance.

-          pH and ORP electrodes can be replaced individually to reduce replacement costs.

GPS: 12 channel parallel (This is availalble for U-52G, U-53G and U-54G.)

Note:
*Battery life based on continuous operation using alkaline C dry batteries when the monitor temperature is over 20℃ and the backlight OFF.
*Accuracy is measured by calibrating 4 points for turbidity and electrical conductivity and 2 points for all other measurements against standard solution.
*Repeatability is measured by the ability to reproduce the results against the standard solution (at 25℃ normal pressure condition).
