Infrared Sensors
Infrared technology has been utilized successfully in industrial and research settings for decades, and with new innovations to reduce costs and increase reliability, Raytek’s infrared technology has created sensors that offer smaller units of measurement. All of these factors have led infrared technology to become an area of interest for new kinds of applications and users.
What are the advantages offered by non-contact temperature measurement?
• Save time; allowing for more measurements and accumulation of data
• Measure moving targets
• Measure hazardous or inaccessible objects (high-voltage parts, great measurement distance)
• Measure high temperatures (greater than 1300°C)
• There is no energy interference; no energy is lost from the target
• There is no risk of contamination and mechanical effect on the target

| Compact Series CI(TM) The CI Series Compact Infrared Sensors accurately and reliably measure the amount of heat energy emitted from an object and convert the energy into a measurable electrical signal. The CI measures target temperatures ranging from 0 to 500°C (32 to 932°F). The onboard electronics are protected by a rugged IP 65 (NEMA-4) stainless steel housing, allowing the sensor to function in ambient temperatures to 70°C (160°F) without cooling. With water cooling, the CI can withstand ambient temperatures up to 260°C (500 |  |

Raytek Spot Size Calculator Software
When planning to purchase or install any non-contact infrared thermometer, the main consideration for the accuracy of the measurement are:
- distance from the thermometer to your target
- size of the measured target at that distance
The Raytek Spot Size Calculator (PC version only) estimates the distance and spot size of all Raytek thermometers to help you with use and installation.

Emissivity of Most Common Materials
Emissivity is the measure of an object’s ability to emit infrared energy. Emitted energy indicates the temperature of the object. Emissivity can have a value from 0 (shiny mirror) to 1.0 (blackbody). Most organic, painted, or oxidized surfaces have emissivity values close to 0.95. Some of our portable thermometers have adjustable emissivity to ensure accuracy when measuring other materials such as shiny metals. You can choose units with adjustable or preset to 0.95 emissivity.
If you are using a thermometer with a fixed, preset emissivity of 0.95, and need to measure a shiny object you can compensate by covering the surface to be measured with spray oil, flat black paint or masking tape. Measure the temperature of the taped or painted surface. That is the true temperature.
Please note, these tables are to be used as a guide only as emissivity changes with temperature and surface finish.
