Water Drop Angle Meter Calibration Specifications

Water Drop Angle Meter calibration specifications are a critical step in ensuring instrument measurement accuracy and consistency. The calibration process typically includes the following steps: 1. Standard Sample Preparation: Calibration is performed using a standard sample with a known contact angle (such as a polytetrafluoroethylene plate with a contact angle of approximately 110°). 2. Instrument Leveling: Ensure the test platform is level, using a spirit level to adjust the level to an accuracy of ≤0.1°. 3. Software Calibration: Use the software's built-in calibration module to adjust the image acquisition system's focus and light source intensity to ensure a clear water droplet outline. 4. Repeatability Testing: Perform multiple measurements (recommended ≥5) on the same standard sample, and calculate a standard deviation of ≤1°. 5. Environmental Control: Calibration should be performed in a constant temperature (23±2°C) and humidity (50±5%RH) environment. Calibration is recommended every three months or after replacing key components.
