Working principle of ammonia nitrogen water quality online analyzer

2025-08-06

The working principle of the Ammonia nitrogen water quality online analyzer is mainly based on the chemical reaction between ammonia nitrogen and specific reagents, indirectly calculating the concentration of ammonia nitrogen by measuring the color change or potential value change of the reaction product. Here are several common working principles: 1、 Colorimetric method Colorimetric method is the most common detection principle, and its specific steps are as follows: Chemical reaction: In alkaline medium, ammonia nitrogen (in the form of free ammonia or ammonium ions) in water samples reacts with salicylates and hypochlorite ions to form blue compounds (salicylic acid spectrophotometric method), or reacts with Nessler's reagent to form yellow brown complexes (Nessler's reagent spectrophotometric method). Absorbance measurement: By measuring the absorbance at a specific wavelength (such as 697nm or 420nm), the concentration of ammonia nitrogen in water can be indirectly calculated. The absorbance is directly proportional to the ammonia nitrogen content, and the concentration of ammonia nitrogen can be calculated through a pre established calibration curve. 2、 Electrode method The electrode method uses a specific composite electrode to directly measure the ammonia nitrogen content in wa...

What are the troubleshooting methods for COD water quality online analyzer

2025-08-06

1、 Hardware troubleshooting 1. Optical system abnormality Phenomenon: Large data fluctuations, no readings or display of "optical path failure". Possible reasons: Optical window contamination (dust, oil stains, reagent crystallization). The light source (LED/xenon lamp) is aging or damaged. The sensitivity of photovoltaic cells (photodetectors) decreases. Troubleshooting steps: Clean optical window: Dip a dust-free cloth in ethanol and gently wipe to avoid scratching the surface. Check the intensity of the light source: Confirm the stability of the light source output through the device self-test function or an external optical power meter. Test the photovoltaic cell: block the light path and observe whether the signal changes as expected (if there is no change, it needs to be replaced). Case: A sewage treatment plant equipment had its optical window covered by algae, resulting in a COD reading that was 50% lower. After cleaning, it returned to normal. 2. Blockage in the flow system Phenomenon: Injection failure, unstable flow rate, or alarm of "flow path blockage". Possible reasons: Reagent crystallization (such as silver sulfate precipitation at low temperatures). Sedimentation of particulate matter (such as sediment and fibers) in water samples. Aging or impro...

What are the maintenance points for digital pH sensors

2025-08-06

1. Regular cleaning Method: Dip a soft cloth or cotton swab in water or specialized cleaning agent, gently wipe the electrode part, and avoid scratching the electrode with hard objects. Attention: Clean the electrodes promptly after measurement to prevent measurement errors caused by the attachment of pollutants (such as algae and oil stains); After cleaning, dry it with filter paper to avoid cross contamination. 2. Calibration management Frequency: Based on the usage scenario, it is recommended to calibrate once a week to once a month; High precision demand scenarios (such as laboratories) require a shorter calibration cycle. Method: Use standard buffer solutions (such as pH 4.01, pH 7.00, pH 10.01) for two-point calibration to ensure sensor response speed and stability. Temperature compensation: before calibration, adjust the temperature compensation setting of the sensor to make it consistent with the temperature of the solution to be measured (the pH value of the standard buffer solution is different at different temperatures). 3. Storage and usage environment Storage: When not in use for a long time, soak the electrode in a 3mol/L KCl solution to avoid drying and electrode aging; The storage environment should be dry, ventilated, and kept away from high temperatures, high humidity, and ...

Digital dissolved oxygen sensor application scenarios

2025-08-06

The digital dissolved oxygen sensor is widely used in scenarios that require real-time monitoring of dissolved oxygen concentration in water due to its high precision, fast response, strong anti-interference ability, and digital integration advantages. The following are typical application scenarios and specific case analysis: 1、 Aquaculture Core requirements Dissolved oxygen is a key parameter for respiration in aquatic organisms such as fish, shrimp, and crabs. Hypoxia can lead to suffocation, death, or growth retardation. Real time monitoring of dissolved oxygen in different water layers (such as pond bottoms and net cages) is required to avoid local hypoxia. Application Cases Factory based circular aquaculture: Multiple sensors are deployed in the aquaculture pool, combined with a PLC control system to automatically adjust the aerator and water flow rate, maintaining dissolved oxygen at 5-8mg/L (suitable range for fish). Pond aquaculture: Real time data is uploaded to a mobile app through buoy sensors, allowing farmers to remotely monitor changes in dissolved oxygen levels and activate oxygenation equipment in a timely manner during nighttime or rainy days. High density aquaculture: For example, in shrimp farming, dissolved oxygen levels below 3mg/L can trigger stress reactions, sensors ...
