These disposable thermometers are characterized by accuracy of up to ±0.1 K and a short response time of 7 s for fast, easy measurement of a patient’s body temperature. The disposable sensors are based on proven ceramic technology for NTC thermistors on a chip basis. New process technologies result in more controlled electrical parameters than can be achieved by other production methods. A significant advantage of these thermometers is their extremely short response time. To reduce measuring time, conventional solutions extrapolate a patient’s expected body temperature in a complex predictive mode. This alternative does not require this, thereby eliminating costs of additional electronics.
