Test Strip

Test sticks are handheld detection tools that directly read parameter values by contacting samples. They use built-in sensors to convert physical or chemical signals into electrical signals, which are then processed by circuits to display results. They are used for on-site rapid detection of indicators such as liquid acidity, alkalinity, and conductivity, commonly applied in scenarios like water quality monitoring and electroplating solution analysis.
Selection
Match sensor types based on the testing items, ensuring the measurement range covers the sample scope. Check whether the response time and accuracy meet on-site requirements, and confirm the material specifications for the operating environment. Verify the calibration methods and data output functions, and evaluate the ergonomic comfort and battery life of handheld devices.
