The Faichney Difference

What's the difference between actual read and predictive-read thermometers?

Accurate readings. Every time.

Predictive reading-type thermometers are quick, but the 'number of samples per measurement' is always fixed, thus the measurement time (response time) is fixed. Since the final (peak) temperature is a calculated value rather than a measured value, the displayed temperature may not always be accurate.

But with Faichney actual-reading thermometers, the 'number of samples per measurement' is not fixed. Factors include the type of measurement (oral, rectal or underarm) and the physiological makeup of the particular person. Therefore, the measurement time (response time) is variable which means the displayed temperature is more accurate.

Actual-Read Thermometers Give Accurate Readings. Every time.

Uses thermistor as temperature sensor. Uses thermistor as temperature sensor.
Normal sampling time for measurement is approximately 1 second (every second, the sensor is energized and the temperature is measured and displayed). Normal sampling time for measurement is approximately 1 second (every second, the sensor is energized and the temperature is measured and displayed).
Uses peak hold algorithm for measurement (the display is updated for every sample when the new measured temperature is higher than the previous measured temperature). Normally uses peak hold algorithm for measurement. However, there are some predictive thermometers that do not use this measurement method. The display is updated regardless of whether the new measured temperature is higher or lower than the previous measured temperature.
If the measured temperature for 10 consecutive samples is less than or equal to the previous sample reading, the thermometer gives a final temperature indication and stops sampling. The temperature is measured for a fixed number of samples (6 to 12). The final temperature is calculated and displayed using a predictive algorithm, based on the sample readings.
The number of samples per measurement is not fixed, but varies depending on:

1. The difference between the initial probe temperature & actual oral temperature

2. The measurement site (rectal measurement is usually faster than armpit measurement)

3. How the measurement is taken (measurement is faster if the mouth is closed for about 5 minutes before taking readings)
The number of samples per measurement is always fixed. Therefore the measurement time (response time) is fast and fixed.
The final temperature indication is most accurate, as it is a measured value. The final temperature indication may not always be accurate, as it is not a measured value but a calculated value.
