Infrared Thermometer (model: CK-T1501,CK-T1502,CK-T1503) is a hand-held, battery powered, infrared Thermometer that coverts a user's forehead temperature, using the infrared energy emitted in the area around the user's forehead to an oral equivalent temperature when meas ure from 3-5 cm of the subiect's forehead with no contact.
lt uses a thermopile sensor with integrated thermistor for the target reading and a thermistor mounted in the head of the thermometer for ambient temperature readings.
It composed by a measuring sensor, PCB, 4 buttons, a LCD and an enclosure. The functions of the three models are similar. The functions of "Temperature Alarm Point", "Temperature Offset", and "Warning Tone Switch" can be set. When measuring body temperature, users need to measure in body mode from 3-5 cm from their forehead. Press the measuring key, after 0.5 second with the sound of "beep", the measurement is completed and the temperature is displayed on the LCD screen. Without any operation, it will close automatically in 15 sec. The No. and stored value of the stored data are displayed at the bottom of the LCD screen. Press "+" / " -" to view the previous or next stored data, it can store 32 sets of measurements.
User contact components are the enclosure and keys. The materials of the components are ABS plastic.
