组件规格

定义
A precision optical component integrated into high-purity sodium nitrite curing salt production equipment that provides real-time visual feedback on chemical concentration levels through calibrated color changes, ensuring consistent product quality and process control in meat curing applications.
工作原理
Operates on photometric analysis principles where specific wavelengths of light interact with sodium nitrite solutions, causing measurable color variations that correlate directly with concentration levels. The system uses calibrated optical sensors and reference standards to detect subtle hue changes, converting them into concentration readings displayed through LED indicators.

常见问题

How often should the color indicator be calibrated?

Calibration is recommended every 90 days using certified sodium nitrite reference solutions to maintain measurement accuracy within ±2%.

Can this indicator detect other curing agents besides sodium nitrite?

No, this specific model is calibrated exclusively for sodium nitrite detection. Different optical configurations would be required for other curing agents like potassium nitrate or sodium nitrate.

What maintenance is required for optimal performance?

Monthly cleaning of optical surfaces with food-grade cleaning solutions, quarterly calibration verification, and annual replacement of O-rings and seals to prevent contamination.
