Color Indicator: Power Supply 24V DC, Pressure Rating 0-10 bar

Q: 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%.

Q: 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.

Q: 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.

Component Specifications

Definition

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.

Working Principle

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.

Materials

Food-grade 316L stainless steel housing, borosilicate glass optical windows, PTFE seals, FDA-compliant epoxy coatings, corrosion-resistant sensor elements
