Description:

The Welch Allyn SureTemp Plus Digital Thermometer (Models 690/692) is a pocket-sized predictive thermometer that uses a fast-response thermistor and proprietary algorithm to deliver oral temperatures in roughly four to six seconds and axillary or rectal readings in 10-15 seconds. A back-lit LCD shows °F/°C, last-temperature recall, battery life, and site icons, while a 60-second pulse-/respiration-timer button instantly switches the instrument to continuous Monitor Mode for core-temperature trending. Interchangeable blue (oral/axillary) and red (rectal) probes with removable wells limit cross-contamination, and a spring-loaded ejector drops used probe covers without hand contact. The handle stores 25 covers, and the 692’s wall bracket holds 50 more and provides electronic security and location ID. Three AA batteries power about 5,000 measurements, and the sealed keypad and IP22 housing tolerate routine disinfection in clinics, wards, or EMS kits.

Economic Advantage:

SureTemp Plus cut bedside temperature time from the 30-plus seconds typical of legacy digital sticks to under six seconds, freeing nursing minutes and improving triage flow. Its predictive algorithm avoids the prolonged dwell of continuous thermometry yet still offers a Monitor Mode when required, so facilities can standardise on one device rather than purchasing both spot-check and continuous units. Long battery life, self-calibration (no annual service), and inexpensive disposable probe covers make the device inexpensive to own, while colour-coded probe wells reduce probe-mixing errors and the need to stock duplicate thermometers for different sites.
