SN-WN-2 portable sludge concentration meter water quality analysis instrument

SN-WN-2 portable sludge concentration meter water quality analysis instrument

1、 Product Introduction
SN-WN-2 portable sludge concentration meter water quality analysis instrument is a detection instrument for measuring sludge concentration in water bodies. Using light scattering method combined with modulated light signal to reduce visible light interference, the measurement process does not require chemical reagents.

This product is suitable for on-site rapid monitoring, emergency screening, and daily inspections of various types of water bodies (surface water, groundwater, drinking water, industrial wastewater, landscape water, etc.), especially suitable for outdoor scenarios where weight based sludge testing is inconvenient.

3、 Sensor parameters and configuration

1. Ordinary sensor with built-in temperature transmitter and automatic temperature compensation function

2. Self cleaning sensor with built-in temperature transmitter and automatic temperature compensation function

3. Special note: The actual measurement value of sludge concentration in the on-site water sample differs from the calibration value of the standard solution used for equipment factory calibration, and the magnitude of the difference depends on the homogeneity of the sludge/sludge in the two solutions. However, in reality, the absorption capacity of different components of sludge on site varies, and there is a certain linear relationship. Therefore, if on-site personnel want to measure values accurately, they must perform on-site calibration and change the measurement slope of the equipment. The device is calibrated with a kaolin mixed solution before leaving the factory, and has good consistency and stability.

4、 Precautions for using sensors

1. The equipment contains sensitive optical components and electronic parts, ensuring that the equipment is not subjected to severe mechanical impact and avoiding any direct mechanical stress during use.

2. During equipment installation, try to avoid cables being too tight or subjected to stress, and prevent the equipment from being exposed to sunlight.

3. Do not forcefully rotate the self-cleaning brush shaft. Regularly check if the self-cleaning brush is working properly and if there is any damage.

4. Please do not touch the measurement window with your hands to avoid damage to the measurement window.

5. When measuring and calibrating equipment, avoid attaching bubbles to the surface of the equipment, especially the measuring window. Regularly check whether there are any attachments or scaling on the measuring window; It can be cleaned with tap water and wiped with a damp soft cloth. For stubborn dirt, some household detergent can be added to tap water for cleaning. Do not scratch the measurement window. If the measurement value is too high, too low, or the value remains unstable, please check if the measurement window of the transmitter is clean.

6. In principle, the equipment should be calibrated before each use, and it is recommended to calibrate it every 3 months for long-term use. The calibration frequency should be adjusted appropriately according to different application conditions (such as the degree of dirt and chemical deposition in the application site).
