Washing Color Fastness Tester
Model Number:SW-12D
[Instrument Name]: Washing Color Fastness Tester
[3rd Lab Qualification Certificate]：
Tianfangbiao Certificate No.：TTTS-MCDT-FZ2512-04
[Patent number]：China Patent No. 23342211
[Calibration Certificate]：Shanghai Branch of the National Textile Metrology Station / Shanghai Textile Group Testing Standards Co., Ltd. Certificate No.ZZ-202603133
[Drafting standard]：Enterprise Standard Q/WZC012-2026SW-12D
[Scope of Application]:
It is used for testing the color fastness of various textiles to washing, dry cleaning, and milling; also used to evaluate the wash-fastness performance of dyes.
[Relevant Standards]：
GB/T 3921-2008 “Textiles — Tests for colour fastness — Colour fastness to washing with soap or soap and soda”;
GB/T 5711-2015 “Textiles — Tests for colour fastness — Colour fastness to dry cleaning using perchloroethylene solvent”;
GB/T 12490-2014 “Textiles — Tests for colour fastness — Colour fastness to domestic and commercial laundering”;
AATCC 61/1A/2A/3A/4A/5A, JIS L0860/0844, BS 1006, ISO 105 C01/02/03/04/05/06/08, DIN, NF, CAN/CGSB, AS, etc.
[Instrument Features]:
1. Features a 7-inch multifunctional color touchscreen for convenient operation.
2. Automatic water level control with automatic water inlet and drainage functions; includes dry-boil protection.
3. Equipped with a safety door switch to effectively prevent scalding and crushing injuries.
4. Uses an imported industrial microcontroller for temperature and time programming; incorporates PID (Proportional-Integral-Derivative) control to effectively prevent temperature overshoot and ensure timing accuracy within ±1s.
5. Uses solid-state relays to control heating elements; features no mechanical contacts, stable temperature, silent operation, and long service life.
6. Features multiple built-in standard programs for automatic operation via direct selection; supports program editing and storage, as well as individual manual operations, to accommodate various testing standards.
7. Test cup manufacturing quality far surpasses similar domestic products:
7.1 Molding process: Zhenchen uses a single-piece die-casting process, whereas similar products use split-welded designs; the die-cast finish is smoother and more aesthetically pleasing, contrasting with the rough appearance of welded units.
7.2 Internal cup treatment: Zhenchen employs a shot-blasting process, unlike the standard forging/casting used by competitors; this additional step densifies the steel structure for greater durability and creates an attractive matte-like surface finish.
7.3 Cup material: Zhenchen uses 316 stainless steel, while competitors often use 201, 202, or 304 grades; the addition of molybdenum in 316 stainless steel provides superior corrosion resistance, making it particularly durable against seawater and acidic/alkaline environments.
7.4 Gasket material: Zhenchen uses imported food-grade silicone, whereas competitors use black rubber or standard domestic silicone; the imported silicone offers better corrosion resistance, making it ideal for tests involving tetrachloroethylene, seawater exposure, and chlorine bleaching.
7.5 Cup weight: Zhenchen’s cups weigh 630g (ASTM standard) and 394g (GB standard), compared to 538g and 342g for competing products; the heavier, thicker construction demonstrates the use of premium materials and ensures greater durability.
7.6 Compression spring material: Zhenchen uses high-quality spring steel, unlike the standard hard steel used by competitors; spring steel provides a superior tactile feel—firm yet responsive—when opening and closing the cup, whereas standard hard steel feels stiff and requires forced manipulation.
[Optional IoT Module Features]:
1. Equipment status statistics: Displays the number of devices currently online or offline.
2. Alarm display: Shows the number and severity levels of active alarms.
3. Real-time test data and status/progress tracking, including specific device information. Real-time data, experiment progress, and total experiment duration
4. Parameters can be set and sent directly to the instrument for modification, enabling bidirectional control between the instrument and the platform
5. Map display: Shows the geographical locations and status of various devices based on device type
6. Laboratory monitoring: Integrates surveillance cameras based on client needs to display real-time video feeds from the laboratory
7. Customized unified management interface for laboratory equipment
8. Temperature and humidity display: Integrates with third-party monitoring platforms to collect and present real-time environmental data from the laboratory
9. Supports device monitoring and alerts via both mobile app and web interfaces
10. Supports customization of the app name and logo
11. Multi-account platform management: Supports multi-level permission settings and account allocation across different devices, departments, and subsidiaries, facilitating unified enterprise management and enhancing device data security
12. Supports maintenance work order submission, allowing manufacturers to review and manage maintenance tasks
13. Supports wired Ethernet connectivity. Wi-Fi and Bluetooth data exchange
14. Capable of simultaneous monitoring and management of multiple devices
15. Capable of storing and analyzing large volumes of test data
16. Supports full-software OTA (Over-the-Air) updates for device evolution
