Product Description

               DDS-307A Laboratory Conductivity Meter


Features

Double-row nixie tube: To show conductivity value and temperature values respectively

Computer-based: It adopts the high-performance CPU chip, high-precision AD conversion technology and

SMT technology to complete the 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: To avoid the electrode polarization and improve the 

Measurement accuracy

25ºC Conversion: Temperature compensation automatic measurement/manual input, with the waterproof and

anti-corrosion design

Network function: RS232 bi-directional communication; it can be equipped with a printer or TLab8.0

communications and data processing software

Measurable high-purity water: Equipped with titanium alloy electrode with the constant of 0.01 cm-1 and an

airtight measuring cell; automatic prompting for measuring terminal.

Standard configuration
 One secondary instrument; one bright or platinum black conductivity electrode with
constant l.0; one temperature electrode; a set of electrode support; one power supply.
