ROI Calculation Logic

If this technology is introduced for humidity and steam monitoring in manufacturing lines, it could significantly reduce the need for expensive electronic sensors and frequent visual inspections by skilled personnel. For example, in an inspection process with annual labor costs of ~$200K (AI est.), early detection of anomalies via this technology's intuitive color change could reduce inspection man-hours by ~20%, leading to ~$40K/year (AI est.) in efficiency gains. Furthermore, against an annual defect disposal cost of ~$135K (AI est.) due to misdetection, a ~20% reduction through improved accuracy could save ~$25K/year (AI est.), totaling over ~$65K/year (AI est.) in potential cost savings.
