Dr. Morepen Thermo Finder Non Contact Infrared Thermometer uses contact less temperature measurement and therefore the body temperature can be measured safely. It measures the temperature 2 to 3 cm away from the body which decreases the possible risk of infections that can be caused by thermometers. Digital LCD display with backlight for easy measurement in dark places also Multi-measurement function which measures both body and wide temperature It can store up to 32 results Non contact measurement, Power saving: Automatic shut off after a minute Powered by two AAA type alkaline batteries Pocket size Particulars Dimensions Measurement Method Infrared (IR) measurement, Non-contact measurement Basic Functions Switches for Multi-measurements (Body and object temperature) Switches for Celsius/Fahrenheit, Memory function, Sound controls (On, Off) Operation Condition 15 0C ~40 0C ( 59 0F ~ 104 0F) Humidity: Below 95% Atmospheric Pressure (hPa) 700~1060 Storage and Transport Condition -20 0C ~50 0C ( -4 0F ~ 122 0F) Humidity: Below 95% Atmospheric Pressure (hPa) 700~1060 Measuring Distance 2 to 3cm from the measuring point Measuring Range Body Temperature: 34 0C~ 42.5 0C (93.2 0F ~ 108.5 0F) Accuracy + 0.4 0F (96.8 0F ~102.2 0F) Other Accuracy : + 0.5 0F Object temperature: 59 0F to 140 0F ( 15 0C to 60 0C) Accuracy : + 4 0F Measuring Time Less than 2 Seconds Resolution 0.1 0F Mode Selection Body temperature, Object temperature Memory Function Automatic memory function.
