Colorimeter WF30 4mm
The WF30 colorimeter is a high-precision, highly stable, and versatile device designed for accurate color measurement. It features three measuring light sources (D50, D65, and F11), two color modes (CIE1976LAB and CIELCH), and a color difference formula (â–³E*ab). The device supports two language options (Simplified Chinese and English) and offers three different measuring calibers. With enhanced data storage capacity, it can be paired with a mini-printer for real-time printing of measurement results. It also works seamlessly with the standard "color analysis system" software.
The 4mm diameter version of the WF30 colorimeter is specifically designed for small areas, curved surfaces, or other special shapes. It provides cost-effective precision for detecting color quality on small parts or complex surfaces, making it extremely convenient for users.

Colorimeter WF30 16mm
The precision colorimeter WF30 is developed based on international standards set by the International Commission on Illumination (CIE) and national standards. It is certified by the National Measurement SCM as a professional colorimeter. The device uses imported key components and is carefully designed for accuracy, stability, ease of use, and affordability. Considering the complexity of colorimeter measurements and diverse user requirements, Weaver has developed the country's first optical measurement colorimeter with a 16mm caliber. If you need to measure objects with textures, pits, or grainy surfaces, or large-sized objects, this 16mm diameter colorimeter is an ideal choice.

High Precision Colorimeter for Printing and Dyeing Clothing Â
There are various types of back muscle fitness equipment, including but not limited to back tension machines, rowing machines, dumbbells and barbells, back stretchers, etc. These devices each have their own characteristics and can be used to exercise different muscle groups in the back, such as latissimus dorsi, trapezius, shoulder and back muscles, thereby comprehensively improving the strength and stability of the back.
1. Back tension machine: It can exercise different muscle groups on the back, such as latissimus dorsi, trapezius, etc. By adjusting the seat and handle, diversified tension training can be carried out at different angles and postures, effectively exercising the width and thickness of the back.
2. Rowing machine: It has a good training effect on the muscles of the back, shoulders, and arms. By adjusting the gear and posture, it can simulate rowing movements, strengthen the strength and endurance of the back and core muscles, and improve cardiovascular function.
3. Dumbbell and barbell exercises: Through different dumbbell and barbell movements, targeted exercises can be performed on the back muscles, such as dumbbell rowing, hard pulling, and flat rowing, to help enhance the strength and stability of the latissimus dorsi and trapezius muscles.
4. Back Stretcher: In addition to exercising the strength of the back muscles, stretching is also an important part of maintaining back health and maintaining correct posture. By doing stretching exercises, one can stretch the back muscles, relieve tension, and promote blood circulation, which helps prevent back pain and injuries.
When using these devices, it is important to maintain the correct posture and movements, and gradually increase the weight and difficulty to gradually improve the strength and endurance of the back muscles. By implementing a reasonable training plan and using it correctly, the strength, definition, and flexibility of the back can be effectively improved.
