Water Drop Angle Tester: Unveiling The Secrets Of Surface Tension

Aug 13, 2025

The DZ-SDJ-500 Water Drop Angle Tester, a precision instrument designed for scientific research and industrial applications, accurately measures the water contact angle on surfaces. The water contact angle directly reflects the surface tension and smoothness of an object and is a key indicator for evaluating surface hydrophobicity and smoothness.

Technical Parameters at a Glance:
Contact angle measurement range: 0-180 degrees, meeting various surface tension testing needs.
Measurement accuracy: ±0.1 degrees, ensuring data accuracy.
Testing Method: Utilizes the sessile drop method, offering a variety of contact angle analysis methods, including manual horizontal measurement, manual inclined measurement, width-height measurement, and manual tangent measurement.

Instrument Features:
Equipped with a 2X fixed-magnification high-definition microscope for easy observation and recording of water droplet morphology.
A digital CMOS camera captures water droplet motion in real time.
Instant screenshot function records changes in water droplet morphology.

Wide Applications:
Suitable for a variety of industries, including glass, chemicals, and electronic machinery, assisting in scientific research and product quality control.

The work surface measures 100mm x 120mm, and features 50mm vertical, 50mm horizontal, and 30mm forward and backward table movement. It also features 30mm vertical telescoping and 150mm forward and backward fixed plate movement to meet diverse testing needs.

The instrument measures 320mm (width) x 530mm (length) x 430mm (height), making it easy to install and use in both laboratory and industrial environments.
