A test sample is placed on top of a heating plate at a constant temperature of 37° (99°F), and a certain amount of water rises from the bottom of the drying test instrument to the center of the plate and saturates the sample.
An anemometer inside the instrument dries the sample. An infrared temperature sensor measures the change in temperature of the sample to determine if the drying is finished, then the drying speed is determined by the test drying time.
This drying rate tester can be networked with smartphone, so you can set parameters and monitor test status remotely, also directly get test results and equipment warning alerts, etc.; Besides, you can share the test results with others.
Efficient and convenient, and more reliable test
With high precision temperature sensor, wind speed sensor and precision drip device, you can complete the test of drying rate quickly in 10 minutes.
The SmartDry Drying Analyzer specially designed parallel cross-flow fan makes the wind speed more uniform and smooth, which can restore the actual evaporation process and make the test results more reliable.
Simple and easy to use
The whole test process will be displayed on the screen and present it as a clear data curve.
Precise appearance design, aluminum alloy hard oxidation surface, durable and easy to clean; seven-inch color touch screen is easy to use.

Frequently Asked Questions for SmartDry Dry Rate Tester
The drying rate testing machine is used to measure how quickly coatings, paints, inks, and other materials dry. It objectively tests the drying time under controlled conditions.
It typically works by applying a thin, even layer of the material to be tested onto a non-absorbent surface like glass or metal. The material is then exposed to controlled temperature and humidity inside the tester. Sensors periodically measure aspects like hardness, gloss, or tackiness to determine when the material is considered dry.
Common materials tested include solvent-based and water-based paints, varnishes, lacquers, inks, coatings, adhesives, and more. Essentially any liquid or suspension-based product that needs to dry can be analyzed.
Typical controls include temperature, humidity, airflow/circulation, material application thickness, and test interval times. More advanced models allow customizing multiple parameters to mimic real-world drying conditions.
Lab-grade testers can measure drying within just a few minutes. Accuracy depends on the specific model and sensors, with some claiming accuracies of just 1-2 minutes depending on the test parameters and material tested.
The objective data on how formulations dry under controlled conditions helps developers optimize variables like resin content, solvents, additives and more to achieve optimal drying performance traits.
