This manual covers the operation, maintenance, and technical specifications of the DDSJ-308F conductivity meter for measuring conductivity, resistivity…
The DDSJ-308F is a novel and practical laboratory analysis instrument designed to precisely measure the conductivity, resistivity, total dissolved solids (TDS), and salinity of aqueous solutions. It also supports measurements for pure water purity, temperature, and salt content in desalination processes. Key features include automatic temperature compensation, auto-calibration, auto-range switching, and GLP compliance with data storage capabilities. This manual is written in Chinese.
