The Non-Contact Thermometer - Rossmax HA500 has advanced infrared temperature measuring technology to provide safe, accurate, reliable and hygienic readings for measuring both temple and object temperature. The temple temperature reading lookup table was calculated and developed based on systematic skin clinical data statistics to accommodate fever and non-fever subjects, under different operating environment. The one second measurement thermometer without contacting skin is a suitable choice for obtaining body temperature and prevents cross contamination by measuring around 5 cm from the temple.
