Overview
QIWEI DDS-307A is a microcomputer type Conductivity Meter with a test conductivity range of 0~ 199μs/cm. It is a precision instrument. The instrument is equipped with temperature Electrode and has automatic temperature compensation function.
Features
1. Microcomputer design, easy to operate.
2. Wide conductivity Measurement range, covering multiple ranges from 0~ 199.9 μs/cm to 20~ 199.9 MS/cm.
3. Equipped with Temperature Electrode, with automatic temperature compensation function (compensation range 0~ 50 ℃).
4. With Data storage function, it can store 50 sets of measurement data, including quantity, Measured value, Measurement unit and temperature value.
5. Conductivity detector constants (0.1, 1 and 10) are supported.
Principle
The Conductivity Meter reflects the Ion concentration of the solution by measuring its conductivity. The instrument has a built-in microprocessor and cooperates with the Conductivity detector Electrode and the Temperature Electrode for measurement. The Temperature Electrode monitors the temperature of the solution in real time, and the microprocessor performs automatic temperature compensation according to the preset compensation algorithm to correct the Measured value to the conductivity value at the standard temperature (usually 25 ° C), thus improving the measurement accuracy.
Applications
It is suitable for various laboratories, industrial sites and water quality monitoring fields that need to measure solution conductivity.
Standards
The data did not mention specific compliance criteria.
Steps
The information does not provide specific operation steps.
Notice
* The working environment should be free of obvious vibration, and there should be no Miscellaneous strong magnetic field interference except for the geomagnetic field.
* Ambient Temperature should be between 5~ 35 ℃.
* environment relative humidity should be less than 85%.
The power supply should use 220V +/- 10%, 50Hz/1Hz AC, and power the instrument through a DC9V adapter.
