4 - Specifications
The Welch Allyn SureTemp Plus module is a fully integrated microprocessor-based thermistor
thermometer designed to take oral, adult axillary, pediatric axillary, and rectal temperatures.
The module acquires patient temperature data using a proprietary Welch Allyn thermometer. The
module is a slave device requiring power and control from a host system. The SureTemp Plus
module calculates temperature and outputs this data to a host system via a serial
communications interface. A proprietary Welch Allyn algorithm in conjunction with the thermistor-
based thermometer provides predictive temperature readings. The board requires a single
voltage input and generates all the necessary internal control voltages.
