The Precision Colorimeter WF30 is developed and manufactured based on the relevant standards of the International Commission on Illumination (CIE) and national standards. It is a professional colorimeter certified by the National Measurement SCM, using imported key components for high accuracy, stability, and ease of use. The device is designed with user-friendliness in mind, making it simple to learn and operate, while offering an affordable price point. This colorimeter is ideal for various industries including plastics, surface treatment, painting, printing, toys, clothing, building materials, rubber, leather, glass, home appliances, textile dyeing, and more. It supports color quality control, color analysis, sample testing, and production line testing. It's also suitable for injection molding, ink, paint, and spray applications. Considering the complexity of color measurements and diverse user needs, Weaver introduced the country's first 16mm caliber precision colorimeter. This model is especially useful when measuring objects with textured surfaces, pits, rough grains, or large sizes, as well as soft or pliable materials. The 16mm diameter ensures more consistent results, particularly for surfaces with irregularities that would be challenging to measure accurately with smaller apertures. In cases where the measured surface is wet, it’s recommended to use a glass plate to protect the instrument's opening. The large measurement port helps ensure more accurate readings, capturing details like texture and pitting effectively, which smaller apertures may miss. **Product Specifications:** - **Model:** WF30 - **Display Mode:** CIELAB / CIELCH - **Color Difference Formula:** Delta E * ab - **Illumination Condition:** CIE 8/d - **Light Source:** LED blue excitation - **Sensor:** Photodiode array - **Measurement Caliber:** φ4mm / φ8mm / φ16mm (selectable) - **Measurement Conditions:** Observer: CIE 10° Standard observer; Light source: D50, D65, F11 (TL84); Contain light way: SCI/SCE - **Measurement Range:** L: 0 to 100 - **Repeated Accuracy:** Delta E < 0.05 (average deviation after 30 measurements of white board) - **Table Difference:** Delta E < 0.2 - **Measurement Interval:** 0.5 seconds - **Storage Capacity:** 100 types of sample data; 200 test sample data - **Language Patterns:** English / Simplified Chinese - **Battery Charging Time:** 8 hours - **Battery:** Li-ion battery, 5000 measurements - **Bulb Lifespan:** Over 5 years, more than 1.6 million measurements - **Display Screen:** TFT true color 2.8-inch (16:9), 400x240 resolution - **External Interface:** USB 2.0 (USB-B) for data communication; RS-232 (115200bps) for micro printer connection - **Working Temperature Range:** 0°C – 40°C (32°F – 104°F) - **Storage Temperature Range:** -20°C – 50°C (-4°F – 122°F) - **Humidity Range:** Relative humidity less than 85%, no condensation - **Weight:** 700g - **Dimensions:** 199 × 68 × 90 mm - **Outer Package Size:** 400 × 240 × 340 mm - **Standard Accessories:** 3000mAh Li-ion battery, AC adapter, USB data cable, CD, user manual, warranty card - **Optional Accessories:** Fluorescent measuring device, liquid measuring device, micro printer Whether you're working in manufacturing, quality control, or research, the WF30 offers a reliable, precise, and versatile solution for all your color measurement needs.
