the human body is converted into heat, with the balance converted into external work or into tissue growth. The circulatory system, in addition to circulating blood for its metabolic characteristics also distributes heat, thus replacing the heat energy lost to the environment, as well as nour- ishing the tissue. The resultant increase in heat energy delivered by the blood causes the temperature to rise until the heat energy lost to the environment again balances with the heat delivered.

It has long been recognized that where there is injury or infection, there is inflammation, but injury or infection of itself does not create heat energy. When there is trauma, whether an injury or abnormal stimula- tion caused by a physical, chemical, or biologic agent, a pathologic process of reactions occurs in the blood vessels and adjacent tissues in response to the perturbation. The natural defense mechanism trig- gered immediately increases the flow of blood to the area of concern, causing the temperature to rise in proportion to the increase in blood flow. However, the maximum temperature can be no higher than that of the core arterial supply to the trauma tissue.

Consider as a simple analogy, the action of washing your hands in a sink. If the water from the hot faucet were to be trickling in a small stream, it is likely it would feel only lukewarm. However, if you were to open that tap full force, the rushing water would feel quite hot. But, no matter how intense the rush, the water could never be hotter than the water from its source of heat, the furnace.

The ancient diagnostic technique of feeling for heat over the body is a longtime indicator of inflammation. While localized temperature eleva- tions may be felt merely by the touch of the hand, the technique is highly subjective, and not sufficiently sensitive to detect the subtle temperature rises indicative of increased cellular or metabolic activity. With the introduction of infrared techniques, accurate surface tempera- ture patterns are immediately quantifiable and any changes easily de- tected. It is this knowledge that enables us to study any disease pro- cess resulting in a change in heat generation or thermal properties of the tissue.

Infrared Thermometry

Temperature is a fundamental property of all matter related to its en- ergy content, and can be described by a numeric value expressed on a scale of temperature. A human’s touch produces an instinctive sense of hot or cold to judge the relative temperature of two objects. How- ever, as a practical matter, clinicians must have a temperature scale that is independent of the observer, by which unknown temperatures

DT 1001-LN, DT 1001-RS, DT 1001, DT 1001-LT specifications

The Exergen DT 1001 series, consisting of the DT 1001-LN, DT 1001, DT 1001-RS, and DT 1001-LT, represents a cutting-edge advancement in non-invasive infrared thermometry technology. These models are designed for accurate and reliable temperature measurement across various settings, making them invaluable tools for healthcare professionals, educators, and individuals monitoring their own health.

A standout feature of the Exergen DT 1001 series is its precision in measuring core body temperature. Utilizing patented infrared technology, these devices detect the thermal radiation emitted by the temporal artery, thus providing an accurate representation of internal body temperature. This non-invasive method is not only safe but also quick, as it can yield results within seconds, making it ideal for both clinical environments and home use.

The DT 1001 series emphasizes ease of use. Equipped with a simple one-button operation, even individuals without technical training can operate the device effectively. The easy-to-read digital display provides clear temperature readings, which can often be coupled with visual and auditory alerts for fever detection, enhancing user experience.

Further enhancing user convenience is the memory function of the DT 1001 series. These models can store multiple readings, allowing users to track temperature trends over time. This feature is particularly useful in monitoring patients with fevers or chronic health issues where regular temperature checks are necessary.

The DT 1001-LN and DT 1001-LT are distinguished by their lightweight and portable design, making them suitable for on-the-go temperature checks. Conversely, the DT 1001-RS is optimized for clinical settings, featuring enhanced durability and robust performance under frequent usage.

Each model has been rigorously validated to meet clinical standards, ensuring that healthcare practitioners can rely on their accuracy. With their advanced technology, user-friendly design, and versatility, the Exergen DT 1001 series stands out as a leading choice in the realm of non-contact thermometers, promoting effective health monitoring for a wide range of users. Their continued popularity highlights a significant trend in modern healthcare towards efficient, precise, and non-invasive diagnostic tools.
