Can My Digital Thermometer Be Wrong?

Do digital thermometers read low?

The researchers found that five of the thermometers produced readings within .

07 degrees Celsius of the reading on the reference thermometer (a mercury thermometer brand most often used by the clinic), but two of the digital units registered lower average temperatures.

One produced a reading lower by ..

Can I use an infrared thermometer on a person?

Yes, you can use a general-purpose medical infrared thermometer to measure human-forehead temperature. Significant changes in the recording of human body temperature have been taking place worldwide in recent years. Human body temperature is well established as one of the key vital signs.

How do I know if my digital thermometer is accurate?

For digital thermometers: Test every six months or so (depending on frequency of use) to make sure the thermometer works properly, using either the ice water or boiling water method. Many digital thermometers have reset buttons. If the accuracy is off, adjust the thermometer to the proper temperature using this button.

What does Lo mean on digital thermometer?

LOW TEMPERATUREIt is standard practice for the majority of digital thermometers to display a “LO” sign when turning the device on. This means “LOW TEMPERATURE”. This is because these types of thermometers are made to measure Body Temperature, so when outside the body, the temperature is usually LOWER.

What does Lo mean on exergen thermometer?

Most of the Exergen devices will either flash BATT or have a battery level icon showing when the battery is low. In the manual it shows LO as meaning the sensor picked up a temperature below 60 degrees Fahrenheit.

How do you fix a digital thermometer error?

Resetting ‘Err’Press the on/off button to switch off the flexible tip or soother thermometer, then press the on/off button again to switch on the thermometer.Proceed as usual in measuring the temperature.

What is considered a fever with an infrared thermometer?

Two studies defined fever as a temperature of over 38°C measured using a mercury-in-glass thermometer in the axilla (12) or an infrared tympanic thermometer (15). One study defined fever as a rectal temperature of 38°C or higher, measured using a mercury-in-glass thermometer (17).

How accurate is a forehead temp?

An ear (tympanic) temperature is 0.5°F (0.3°C) to 1°F (0.6°C) higher than an oral temperature. An armpit (axillary) temperature is usually 0.5°F (0.3°C) to 1°F (0.6°C) lower than an oral temperature. A forehead (temporal) scanner is usually 0.5°F (0.3°C) to 1°F (0.6°C) lower than an oral temperature.

Can you calibrate a digital thermometer?

Yes. You can “Calibrate” any thermometer. Some Digital thermometers have a ‘re-set’ button that allows you to reseat the digital reading, but even Non-Adjustable Digital thermometers can be calibrated to check accuracy.

Why would a thermometer be inaccurate?

Wireless & Extended Range Thermometers 10-20° Inaccuracy: This is usually a result of moisture seeping into the probe and throwing off the temperature detected by the device within that reads temperature.

How do I check my temperature with an infrared thermometer?

Measures thermal radiation (infrared) emitted from ear and forehead to infer body temperature For ear thermometer, a new ear-probe jacket should be used for different person; the ear canal must be pulled straight when measuring.
