Optosky Natural Rubber DRC/TSC Determination NIR Solution

The Optosky Dedicated Natural Rubber Near-Infrared (NIR) Spectrometer is a rapid testing device developed specifically for the natural rubber industry. It provides rapid determination of critical quality indicators, such as Dry Rubber Content (DRC) and Total Solids Content (TSC). This solution is ideal for quality inspection and control across the entire natural rubber supply chain—including latex harvesting, processing, and trading.

Industry Pain Points

• Extremely Slow Traditional Testing: The conventional oven-drying method for determining DRC takes 6 to 8 hours, severely bottlenecking latex collection and factory throughput.
• Lack of Rapid Field Tools: Latex collection points often lack quick testing methods, easily leading to transaction disputes regarding latex quality.
• High Operational Costs: Manual oven-drying procedures are tedious, heavily consume energy, and require immense labor costs.
• Unmonitored Quality Fluctuations: During the manufacturing phase, the DRC cannot be monitored in real time, causing significant fluctuations in final product quality.
• Prohibitive Equipment Pricing: Imported alternative instruments are overpriced with high maintenance costs, making wide-scale industry adoption difficult.
