TOC Sensor (Total Organic Carbon)

Measuring organic carbon content to ensure purity, safety, and process integrity.

What Does a TOC Sensor Measure?

A TOC sensor measures the total amount of organic carbon present in water or process liquids. TOC represents the combined concentration of all organic compounds and is a critical indicator of contamination, cleanliness, and process suitability.

Working Principle

TOC sensors operate by oxidizing organic carbon into carbon dioxide (CO₂) and measuring the resulting CO₂ concentration. The measured value is directly proportional to the organic carbon content of the sample.

Common Types of TOC Sensors

Signals & Outputs

Direct & Indirect Meaning of TOC Data

Direct Meaning

The measured value directly represents the concentration of organic carbon in a liquid.

Indirect Meaning

TOC trends indirectly indicate contamination events, cleaning effectiveness (CIP), water purity degradation, and risks to sensitive manufacturing processes.

Industries Using TOC Sensors

Role of IoT in TOC Monitoring

With Industrial IoT integration, TOC sensors enable continuous purity monitoring, automated contamination alerts, validation of cleaning processes, and compliance-ready documentation.

IndustrioPedia Perspective

The TOC Sensor is a purity sentinel. By measuring total organic presence, it safeguards sensitive processes, ensures regulatory compliance, and upholds the highest standards of quality and safety.
