Non-contact Infrared Thermometers

Measuring a person’s temperature can be done in several ways. One method to measure a person’s surface temperature is with the use of non-contact infrared thermometers (NCITs). NCITs may be used to reduce cross-contamination risk and minimize the risk of spreading disease. While typically 98.6°F (37.0°C) is considered a “normal” temperature, some studies have shown that "normal" body temperature can be within a wide range, from 97°F (36.1°C) to 99°F (37.2°C). Before NCITs are used, it is important to understand the benefits, limitations, and proper use of these thermometers. Improper use of NCITs may lead to inaccurate measurements of temperature.

 

Benefits of NCITs

Non-contact approach may reduce the risk of spreading disease between people being evaluated

Easy to use

Easy to clean and disinfect

Measures temperature and displays a reading rapidly

Provides ability to retake a temperature quickly

 

Limitations of NCITs

How and where the NCIT is used may affect the measurement (for example, head covers, environment, positioning on forehead).

The close distance required to properly take a person’s temperature represents a risk of spreading disease between the person using the device and the person being evaluated.

 

Proper Use of NCITs

The person using the device should strictly follow the manufacturer’s guidelines and instructions for use for the specific NCIT being used. The manufacturer’s instructions for use typically include the following information and recommendations for proper use:

 

Preparing the Environment and NCIT:

The use environment may impact the performance of the NCIT. Instructions will typically include recommendations for optimal use, such as the following:

Use in a draft-free space and out of direct sun or near radiant heat sources.

Determine if conditions are optimal for use. Typically, the environmental temperature should be between 60.8-104 ºF (16-40 ºC) and relative humidity below 85 percent.

Place the NCIT in the testing environment or room for 10-30 minutes prior to use to allow the NCIT to adjust to the environment.

What You Should Know About Disposable Gloves

While disposable gloves are often used in a medical or industrial setting, they also have many uses around the home and workplace that don't involve touching a patient in an exam room or a specimen in a lab. In order to see which gloves performed the best, we put them through a series of experiments.   •  Durability  —We took a box cutter to each glove, and determined its durability by rating how easy it was to slice through the glove material. •  Resistance to tearing  —One the glove had a slice in it, we added weights that hung from the torn glove to see how much weight it would take for the glove to be torn apart when it was already damaged. •  Temperature resistance  —After setting the water temperature to "uncomfortably hot", we stuck our glove-covered hands under the water to see how long it took for us to actually feel the burn. •  Chemical resistance  —With most disposable gloves, if you get some sort of chemical (like a heavy-duty cleaning agent) on them, after a

The Best Guide to Textured Gloves

    The inner surface of your gloves needs to be smooth and comfortable. Have you ever thought about the glove’s outer surface? Textured gloves happen to have a rough outer surface. What are textured gloves? Have you ever examined the outer surface of a glove and noticed indentations? I am sure you have. These are what we call textured gloves.  Unlike regular gloves, they have patterns on their outer surface. These patterns can be straight lines, sand-like exteriors, dots, or geometrical shapes. Thus, you will find that there are 3 types of gloves: smooth, micro-roughened, and aggressively textured. So, let’s differentiate between the three types. Micro-roughened gloves This type of texture is most common in manufacturing latex and nitrile gloves. Micro-roughened nitrile gloves constitute 95% of manufactured nitrile gloves. These gloves will look as if they have tiny sand particles on their outer surface.  Thus, this provides a moderate option between smooth gloves and aggressively tex
