use in waterworks, aquiculture, city sewage processing, environmental processing and beverage industry.

Characteristics:

1. With the function of double displays of dissolved oxygen concentration value and temperature, dissolved oxygen saturation value and temperature

2.Measuring D.O. concentration, saturation, electrode current and temperature; With the functions of automatic temperature compensation and calibration of zero oxygen, full scale, atmosphere pressure and salinity.

3.The meter has the function of protection from electricity cutting off.

4.Automatic temperature compensation

5.With Measuring results can be stored, deleted, viewed and printed. At most 250 sets of data can be stored.

6.With RS-232 interface which is connected and with Model TP-16 printer to print measuring results or connected with computer to communicate.

7.Grade of the case protection is IP65
