Product Description

DDS-308A laboratory Conductivity Meter

DDS-308A is a laboratory conductivity meter with the most powerful functions and the most convenient operation in the market. It is featured by multi-function and high accuracy of measurement; English display and English menu guide make the operation very convenient. It can be widely used for the continuous monitoring of the conductivity values of the solutions in thermal power plants, chemical fertilizer, metallurgy, environmental protection, pharmaceutical, biochemical, foodstuff, running water, etc.


Features
LCD display, menu and notepad in English.
Computer-based: It adopts high-performance CPU chip, high-precision AD conversion technology and SMT technology to complete multi-parameter measurement, temperature compensation and automatic range switching,with high precision and good repeatability.
Reliability: Single-board structure, touch button, no switch knob or potentiometer
Automatic conversion of measuring frequency: The electrode polarization is avoided and thus the
measurement accuracy is improved.
25ºC Conversion: Temperature compensation automatic measurement/manual input, ultra-pure water automatic temperature compensation
Network function: RS232 bi-directional communication, which can be equipped with a printer or TLab8.0 communications and data processing software.
Historical data: 3000 data can be stored.
Notepad: 200 messages can be recorded.
Built-in real-time clock: Providing a variety of functional time references.
Measurable high-purity water: Equipped with titanium alloy electrode and airtight measuring cup with
constant 0.01 cm-1
