The high quality NH3 gas sensor is designed for accurate detection in the 0-100ppm range. The gas sensor operates at 5V ± 0.5V DC and consumes as little as ≤1W, making it ideal for domestic and industrial gas detection. It operates efficiently over a wide temperature range of -20°C to 50°C and relative humidity of 15% to 95% without condensation. Utilizing natural diffusion and an electrochemical tri-electrode, it has a resolution of 1 ppm and an error of ≤±3%. Communication is via the UART interface at a baud rate of 9600 in accordance with the Modbus-RTU protocol and features a 0-2V analog output. The gas sensor is lightweight (10 grams) and requires only 30 seconds to warm up, ensuring reliable and efficient detection of ammonia.

Tips: How to maintain the ammonia (NH3) gas sensor?

  1. Turn Off the Power: For safety, always turn off the power before starting maintenance.
  2. Periodic Calibration: Calibrate the sensor periodically to maintain accuracy. Follow the manufacturer's instructions for calibration procedures.
  3. Clean Environment: Keep the sensor free of dust and contaminants. Use a soft brush or compressed air to clean the sensor surface.
  4. Check Connections: Check electrical connections for any signs of wear or corrosion. Make sure all connections are secure.
  5. Avoid Moisture: Ensure that the sensor is not exposed to excessive moisture during maintenance to prevent damage.
  6. Replacement Parts: Use only genuine replacement parts recommended by the manufacturer to ensure compatibility and reliability.
  7. Documentation: Keep a log of maintenance activities, including calibration dates and any repairs performed.

Following these steps will help ensure the longevity and accuracy of your NH3 gas sensor.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
