The contact thermometers consist of a temperature sensor, a liquid crystal display, a button battery, an ASIC and other electronic components. It uses a temperature sensor to output an electrical signal, directly outputs a digital signal or converts a current signal (analog signal) into a digital signal that can be recognized by an integrated circuit, and then displays it through a display (such as a liquid crystal, a digital tube, an LED matrix, etc.). The digital form of temperature can record and read the highest value of the measured temperature.
There are three different types of contact thermometers:
1) Hard Rod type: A thermometer commonly used in the home, using axillary measurement and oral measurement.
2) Soft stick type: The front end of the soft head electronic thermometer can be bent freely, multi-directional, no dead angle, suitable for measurement of various parts, generally adopting three methods of mouth, armpit and anus.
3) Pacifier type: Baby pacifier electronic thermometer is designed and manufactured for the physiological characteristics of infants and young children. The parts are all designed with a smooth arc, the curvature is based on the baby's mouth shape, and the silicone nipple contains a temperature sensor.
These contact thermometers are highly accurate and generally do not exceed -0.1 °C, making reading and carrying convenient.
This electronic thermometer can be cleaned with a damp cloth. If it is waterproof, it can be washed directly in water. Do not place in high-pressure gas, high temperature environment, and do not touch with corrosive materials.
