Product Description

 

DDS-307A Lab Conductivity Meter

DDS-307A is an improved conductivity meter; based on DDS-307 on the market, it is added with the automatic temperature compensation function, with high price-performance ratio. It can be widely used for continuous monitoring of conductivity values of the solutions in thermal power plants, chemical fertilizer, metallurgy, environmental protection, pharmaceutical industry, biochemical industry, foodstuff and running water.

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

25℃ 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.

 

Technical Indexes

1. Display: Double-row Nixie tube displays the conductivity and temperature values respectively.

                  10~30000 μ s/cm (Electrode: K=10.0)

4. Resolution: 0.001μ s/cm, 0.1

5. Electrode constant: 0.001~15.0 cm-1 set by the software

6. Temperature compensated range: automatic: 0-99.9 ℃, manual: 0-99.9 

7. Temperature coefficient: 0~10%/℃ (with 25℃ as the reference temperature)

8. Accuracy: ±l0%FS, ±0 3

9. Communication interface: RS232 bi-directional communication interface

10. Power supply: AC220V ± 22V, 50Hz ± 1Hz, external power supply

11. Working conditions: ambient temperature: 0-60℃; relative humidity: ≤90

12. Power-down memory: > 5 years

 

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.
