Page 6: General Information
1.1 Description Thank you for choosing the optris® CTratio infrared thermometer. The sensors of the optris CTratio series are noncontact infrared temperature sensors. They calculate the surface temperature based on the emitted infrared energy of objects. The CTratio can work in the 1-color-mode as well as in the ratio- or 2-color-mode [►9 Basics of Infrared Thermometry]. - Page 7 The CTratio sensing head is a sensitive optical system. Please use only the thread for mechanical installation. • Avoid abrupt changes of the ambient temperature. • Avoid mechanical violence on the head – this may destroy the system (expiry of warranty). •...

- Page 18 Technical Data Sensor placement [1C mode] The size of the measuring object and the optical resolution of the infrared thermometer determine the maximum distance between sensing head and measuring object. In order to prevent measuring errors the object should fill out the field of view of the optics completely. Consequently, the spot should at all times have at least the same size like the object or should be smaller than that.

Page 48: The Ratio Principle
Basics of Infrared Thermometry 9.1 The Ratio Principle The 2-color ratio technology makes possible accurate and repeatable temperature measurements that are free from dependence on absolute radiated energy values. In use, a 2-color sensor determines temperature from the ratio of the radiated energies in two separate wavelength bands (colors). The benefits of 2-color sensors are that accurate measurements can be made under the following conditions: ►... - Page 49 1-color sensors see polluted atmosphere and dirty windows and lenses as a reduction in energy and give much lower than actual temperature readings. Targets Smaller Than Field of View When a target is not large enough to fill the field of view, or if the target is moving within the field of view, radiated energies are equally reduced, but the ratio of the energies is unaffected and measured temperatures remain accurate.

Page 50: Emissivity
Emissivity 10 Emissivity 10.1 Definition The intensity of infrared radiation, which is emitted by each body, depends on the temperature as well as on the radiation features of the surface material of the measuring object. The emissivity (ε – Epsilon) is used as a material constant factor to describe the ability of the body to emit infrared energy. -

and take the temperature of the sticker. Afterwards, determine the temperature of the adjacent area on the measuring object and adjust the emissivity according to the value of the temperature of the sticker. ► Cove a part of the surface of the measuring object with a black, flat paint with an emissivity of 0,98. Adjust the emissivity of your infrared thermometer to 0,98 and take the temperature of the colored surface. -
Page 52: Characteristic Slope Values
Emissivity 10.4 Characteristic Slope Values The slope is the quotient of the emissivity of both of the overlapping wavelength bands. The factory default value for the slope is 1,000. The following slopes are typical reference values. The real slope can vary depending on the metal alloy and surface finish. - Page 53 This figure is showing the typical temperature reading of a ratio thermometer optris CTratio in both the 1- color- and the 2-color-mode in addiction of increasing contamination of the optical transmission path in- between the target and the ratio thermometer. Due to the ratio principle the 2 channel signal (upper curve) stays very stable over a wide range of attenuation up to over 90 %.
