Spray Rating Tester LSTR-A10

The Labtron Spray Rating Tester LSTR-A10 is designed to assess the water repellency of fabric surfaces by simulating a spray of water under controlled conditions. It helps determine how resistant a textile is to surface wetting, which is crucial for fabrics used in rainwear, upholstery, shoes, and outdoor gear. This instrument is suitable for use in various industries such as textiles, footwear, toys, and general material testing. It is commonly used in residential, commercial, and light industrial environments to ensure product quality and performance. The tester complies with several international standards, including ISO 4920, AATCC 22, GB/T 4745, and JIS L1092, making it a trusted tool for laboratories and quality control departments worldwide.

The Labtron LSTR-A10 Spray Rating Tester is built with high-quality stainless steel, which provides excellent rust resistance and durability, ensuring long-term use even under rigorous testing conditions. The robust construction maintains stability and accuracy during testing. Additionally, it features a simple and user-friendly design, which makes it easy to operate without requiring highly specialized training. The inclusion of essential accessories such as a drip tray, measuring glass, nozzle, and specimen fixture further enhances its reliability and functionality. These features combined make it a dependable instrument for any laboratory focused on textile quality and performance testing.

The Labtron Spray Rating Tester LSTR-A10 performs the water repellency test by spraying water from a nozzle positioned 150 mm above the center of the fabric sample. The sample is placed on a holder with a 150 mm diameter and mounted at a 45° angle. Water is then poured into the measuring flask and sprayed evenly across the fabric surface. After the test, the fabric is evaluated for the degree of surface wetting. The main components of the tester include a spray nozzle, sample holder, water pan, drip tray, and measuring glass. The test is simple but provides valuable insight into a fabric’s ability to resist wetting, helping manufacturers improve product quality.

The Labtron LSTR-A10 offers precise and consistent testing through its well-designed specifications. The nozzle-to-sample distance is fixed at 150 mm, and the sample is held at a 45° angle, ensuring uniform test conditions. The sample holder has a diameter of 150 mm, and the water pan measures 500 × 400 × 30 mm, which helps collect excess water and prevents spills. The 500 ml measuring flask allows controlled water application. With a compact dimension of 500 × 400 × 500 mm and a net weight of 6 kg, it is lightweight yet stable. These accurate measurements and standardized settings ensure that test results are consistent and reproducible across different labs and conditions.

The Labtron Spray Rating Tester LSTR-A10 complies with multiple widely recognized international testing standards, including ISO 4920, AATCC 22, GB/T 4745, and JIS L1092. These standards define the procedures and evaluation criteria for testing the water repellency or surface wetting resistance of fabrics using a spray test method. Compliance with these protocols ensures that the test results from the LSTR-A10 are reliable, comparable, and accepted globally across different markets and industries.
