Description
The Level 1 Tympanic Temperature Sensor measures temperature at the ear canal for detection of hypothermic and hyperthermic conditions. Its foam cylinder expands in place to secure the sensor and seal out outside air, so readings stay accurate even without membrane contact.
- Self-Seating Foam Fit – The squeezed foam cylinder expands in the ear canal to secure the sensor and block outside air
- Accurate Without Contact – The air seal keeps measurement accurate even when the sensor does not touch the tympanic membrane
- Documented Accuracy – Thermistor accuracy of plus or minus 0.2 degrees C from 5 to 45 degrees C
Ear Canal Temperature Sensor for Atraumatic Continuous Monitoring
Tympanic temperature monitoring is a well accepted clinical procedure, and this sensor is designed for atraumatic placement near the tympanic membrane. The sensor sits in the center of a PVC foam cylinder that the clinician squeezes and rolls before insertion. Once in place, the foam expands back to its original size and makes physical contact with the walls of the ear canal. That expansion does two jobs at once, securing the sensor and preventing outside air from communicating with the measurement site. The result is continuous monitoring that does not depend on perfect membrane contact. This adult configuration is single use, supplied in sterilized packaging, 20 per box.

Why Clinical Teams Choose Level 1 Tympanic Sensors
Ear-based monitoring fails when the sensor migrates or outside air leaks past it. The expanding foam design attacks both failure modes mechanically, so the reading stays trustworthy over a long case. It is continuous core-adjacent monitoring without an invasive probe.
- Stays Where It Is Placed – Foam expansion secures the sensor in the canal for the full monitoring period
- Sealed Measurement Site – Blocking outside air protects accuracy hour after hour
- Non-Invasive Continuity – Continuous readings without esophageal or rectal placement
Frequently Asked Questions
How does the sensor stay in place?
The sensor sits in a PVC foam cylinder that is squeezed before insertion and expands in the ear canal, securing the sensor and sealing out outside air. The foam contact also holds the sensor steady through the monitoring period.
Does it need to touch the eardrum?
No. The foam seal keeps measurement accurate even when the sensor is not touching the tympanic membrane.
How accurate is it?
The thermistor accuracy is plus or minus 0.2 degrees C in the range of 5 to 45 degrees C. The foam seal protects that accuracy through long monitoring periods.
Is it reusable?
No. It is a single use disposable sensor supplied in sterilized packaging.
How is it packaged?
The adult sensors are supplied 20 per box and sold by the case. Boxes stock cleanly at the anesthesia cart and ICU supply room.
