2.1.2 Features
INE-DDBJ-350 portable conductivity meter is a new design meter with following
features:
 It adopts new microprocessor technology, 4.3 "TFT touch screen, reach 65k color
gamut;
 It adopts li-on to stand long time for operation;
 It adopts new UI design specification, navigational operation and sliding operations;
 It supports the measurement of conductivity, resistivity, TDS, temperature and
salinity value;
 It supports balance condition judgment, balance conditions prompt. Supports alarm
settings, support users to customize the alarm value;
 It supports multiple reading methods, including continuous reading method, smart
reading method and timed reading method, for long-timing or interval timing;

It supports to store measuring results of conductivity, TDS, salinity, resistivity, each
for 1000 sets;
 It supports multiple view methods that user views stored data according to storage
number and storage time, the results will display in curve;
 It supports conductive probe calibration function, calibrate Cell constant or TDS
factor;
 It supports multi-points conductivity calibration, up to 2 points;
 It supports automatic identification of conductivity standard solution, default to four
kinds of GB standard solution;
 It supports a variety of conductivity compensation mode, including pure water
compensation;
 it supports automatic temperature compensation, automatic calibration, automatic
range and automatic frequency switch functions in the full range;
 It supports GLP norms, to set the user ID, sample ID;
 It supports firmware upgrade function;
 It supports USB can be connected with PC;
 It supports the function of power-off protection. When the meter is to be turned off or
automatic shutoff, the stored measuring data, calibration data and setting
parameters will not be lost;
 It supports power consumption management, including automatic backlight
adjustment, automatic power off. In the set time, the meter will automatically reduce
the backlight if there is no operation; If there is no further operation, the meter will
automatically power off to save power consumption.
