WS-3 type micro moisture analyzerWorking principle

A new instrument for the determination of trace moisture using the coulometric method combined with the Karl Fischer method. This instrument adopts high electrolysis current and automatic current control, with direct digital display of measurement results. It has fast measurement speed, short analysis process time, high accuracy, and simple operation, making it an efficient and fully automatic moisture measurement instrument. Mainly used for the determination of moisture in substances such as petroleum, chemical, pharmaceutical, pesticide, textile, pigment, paint, etc.

WS-3 typeComposition of instruments

The instrument mainly consists of three parts: the host, electrolytic cell, and magnetic stirrer. When the host and magnetic stirrer are installed on the same base for use, place the electrolytic cell in the clamp of the magnetic stirrer, as shown in the external structure diagram of the host.

1. LED digital display, displaying the moisture content of the tested sample, in units of; Microgram of water.

2. END endpoint indicator light

DET measurement potential display, the moisture content in the sample can be displayed by the potential.

4. TITR electrolysis display: When all the water in the sample is electrolyzed, the electrolysis reaches the endpoint, and the endpoint indicator light is on. The buzzer emits intermittent sound, and the number displayed on the digital display is the amount of water in the sample.

5. Start up, press this button before injecting each sample, the red indicator light next to the button will light up, and the display will reset to zero.

6. Electrolysis switch, controls the on/off of electrolysis current (red indicator light next to the on button lights up)

7. Mixing switch, control the on/off of the mixer (the red indicator light next to the on button lights up)

8. Cathode chamber drying tube

9. Anode chamber drying tube

10. Electrolytic electrode

11. Cathode chamber

12. Anode chamber grinding plug

13. Measuring electrodes

14. Anode chamber

15. Mixing rod

16. Cooling fan

17. Variable speed potentiometer. Used to adjust the mixing speed, clockwise is "fast" and counterclockwise is "slow"

18. Power switch (the switch light is on when turned on)

19. Fuse holder. Equipped with a 1A fuse inside.

20. AC power socket. Used to connect 220V AC power supply.

Note: The measuring socket is plugged into the measuring electrode, and the electrolytic socket is plugged into the electrolytic electrode.
