DDSJ-308A Conductivity Meter Introduction
The DDSJ-308A conductivity meter is an intelligent laboratory routine analytical instrument for the accurate measurement of conductivity and temperature, total dissolved solids (TDS) and temperature of aqueous solutions in the laboratory. It can also be used to measure pure water. Purity and temperature, as well as the determination of salt content in desalination of seawater and seawater (based on NaCl). Features
1.Double digits LCD display with big screen and blue back light, display conductivity value and temperature value
2.It can be used to measure conductivity, TDS, salinity and temperature.
3.Automatic temperature compensation, automatic calibration, automatic range changing and electricity cutting off protection
4.Measurement results can be stored, deleted, consulted and printed. It can store at most 50 sets of measurement data.
5.With RS-232 interface, Model TP-16 printer can be connected
6.With calibration function, can set electrode constant and TDS switching coefficient
7.Measuring ultrapure water with using K=0.01cm-1 titanium alloy electrode and sealing measuring cell
8.Connecting PC with the meter with selecting data soft Technical parameters
