Wireless Droup Counter Sensor

I. Working Principle

Infrared light shines into the sample cuvette, and the light is refracted in all directions due to particles in the water. The detector composed of a photosensitive diode is at an angle of 90° to the light source. The refracted light is measured and converted into voltage data and then into turbidity data in NTU.

II. Specifications

Maximum counting speed: 6 drops/sec.
Resolution: 1 drop

III. Structure and Function

1. The sensor terminal comes with a 1.8-inch color LCD screen.

2. The sensor terminal is equipped with 5 function buttons. The operation interface is simple and convenient.

3. The sensor terminal supports high-speed USB data channel, which enables high speed transmission to the datalogger.

4. The sensor terminal supports wireless communication with experimental terminals.

5. The sensor terminal has a built-in removable battery with a large capacity.

6. The sensor terminal is designed with a hidden buckle sensor interface to support combined experiments with other sensors.

7. The sensor terminal has designed a fixation spot to get it fixed on the iron frame conveniently and combined with traditional lab equipment for experiments.

8. The sensor terminal supports the latest operating systems, such as iOS, Android, windows operating systems, etc.

IV. Typical Applications

The sensor measures water clarity, an important indicator of water quality. High turbidity means the water is cloudy, low turbidity means the water is clear. Suspended particles in the water can cause reflection and darken the water. Therefore, the more suspended particles in the water, the turbid the water will be. Application scenarios include: experiments such as turbidity before and after using a water filtration device, monitoring the turbidity of a solution after chemical treatment, analyzing the turbidity of water containing various bacteria, etc.

V. Caution

This product is suitable for educational use only and is not suitable for industrial, medical, research, or commercial applications.

VI. Usage Tips

1. For accurate readings, fill the test tube with at least 4 ml of sample to the cap, tighten the cap to prevent light from entering, and avoid measuring under strong light;

2. Avoid using or diluting dark-colored samples, as dark-colored samples will have greater errors;

3. Before measuring turbidity, remove “suspended solids” or large, visible sediment particles from the sample (use a pipette or filter to remove the sediment), as these substances can cause reading errors;

4. For accurate measurement, please measure immediately after preparing the sample and before the suspended particles in the solution settle;

5. Gently shake the test tube back and forth to ensure that the particles are evenly mixed. Do not shake the test tube violently or produce bubbles!

6. When you are finished using it, rinse the sample colorimetric tube with distilled water;

7. Generally add 2.5 to 4 ml of test solution to the container to ensure that the liquid level is above the emission angle of the diode. Otherwise, errors will be caused in the measurement results.
