The MT-100 is MicroTemp's smallest IRT model. At 3.25"H x .75"W, it is only the size of a finger. Don't let the size fool you - the MT-100 is also very capable IRT.
TEMP RANGE: -27°F to 356°F
DISTANCE TO SPOT (D:S) RATIO: 1:1
RESPONSE TIME: 1 second
MODES: CELSUIS and FAHRENHEIT
What is Infrared Thermometer Technology:
Infrared thermometers measure temperature using blackbody radiation (generally infrared) emitted from objects. They are sometimes called laser thermometers if a laser is used to help aim the thermometer, or non-contact thermometers to describe the device’s ability to measure temperature from a distance. By knowing the amount of infrared energy emitted by the object and its emissivity, the object's temperature can be determined.
The most basic design consists of a lens to focus the infrared energy on to a detector, which converts the energy to an electrical signal that can be displayed in units of temperature after being compensated for ambient temperature variation. This configuration facilitates temperature measurement from a distance without contact with the object to be measured. As such, the infrared thermometer is useful for measuring temperature under circumstances where thermocouples or other probe type sensors cannot be used or do not produce accurate data for a variety of reasons.
Infrared thermometers can be used to serve a wide variety of temperature monitoring fuctions. A few examples provided to this article include:
Checking mechanical equipment or electrical circuit breaker boxes or outlets for hot spots
Checking heater or oven temperature, for calibration and control purposes
Detecting hot spots / performing diagnostics in electrical circuit board manufacturing
Checking for hot spots in fire fighting situations
Monitoring materials in process of heating and cooling, for research and development or manufacturing quality control situations
There are many varieties of infrared temperature sensing devices available today, including configurations designed for flexible and portable handheld use, as well many designed for mounting in a fixed position to serve a dedicated purpose for long periods. Specifications of portable handheld sensors available to the home user will include ratings of temperature accuracy (usually plus or minus a degree or two), plus some other not so obvious measurements. The distance to spot ratio (D:S) measures the diameter of the temperature measurement area as it relates to the distance between the device and the surface being read. For instance, if your target area was one inch wide and you could get no closer than 12 inches to your target, you would need a sensor with a D:S of 12:1 or greater. Another feature is whether the sensor has a fixed or adjustable emissivity setting. If fixed, you would not get accurate readings from shiny surfaces (because most sensors are calibrated for non-shiny surfaces). Fixed emissivity sensors can be effective on shiny objects by just using tape or paint on your surface to compensate."
