Astl is a spray-rating testing machine used to evaluate water-wetting resistance. It has spray nozzles that precisely comply with water flow standards with high precision. It is designed with all-metal structure material. It should be kept at a 45-degree angle at a certain distance while in use. Moreover, making a wet sample requires spraying a fixed amount of distilled water through a standard nozzle at a 45° angle to the surface of the sample 150 mm below.
