Suprema thermal camera measures the temperature quickly and accurately by combining its high-resolution camera (19,200 pixels) with patented face recognition algorithm that pinpoints the upper area of the face.
Temperature accuracy ≤±0.5°C(0.9°F)*/±0.3°C (0.5°F)**
For ±0.5°C accuracy, use the device:
In recommended ambient temperature (10°C to 35°C or 50°F to 95°F)
90 minutes after turning on for self-calibration
According to KOLAS(Korea Laboratory Accreditation Scheme) calibration certificate
