ri-thermo Tympanic Thermometer
Riester · 01835
Article No. AK-FD-459
The ri-thermo tympanic thermometer enables fast, precise and hygienic temperature measurement in the daily work in a medical practice, hospitals and clinical care settings. Using infrared measurement technology, it delivers accurate readings within 1–2 seconds, supporting efficient patient assessment when time is critical. A probe guidance indicator assists with correct positioning in the ear canal, ensuring consistent and reliable measurement results across different patient groups. The use of latex-free and BPA-free disposable probe covers supports hygienic operation and reduces the risk of cross-contamination in clinical environments. Designed for ergonomic one-handed operation, the device allows easy use even in high-pressure situations or with uncooperative patients. The automatic ejection of probe covers via push-button function further improves workflow efficiency and infection control. The thermometer supports up to 3,000 measurements per battery set, reducing maintenance requirements and ensuring long-term operational reliability. An optional Bluetooth® interface enables seamless data transfer and integration into patient documentation systems, supporting digital workflows
