SAFETY INSTRUCTIONS
Please read carefully the instructions given in TECHNICAL SPECIFICATIONS, especially
the connection and operating instructions as well as the connection instructions and con-
figurations dealt with in SYSTEM START-UP.
ATTENTION
In case of wrong connection,
the device might be destroyed.
The Infrared Radiation Thermometer is an optical measuring instrument. Dirty lenses will
lead to measuring errors. Please pay attention to the instruction given in MAINTENANCE
AND CALIBRATION.
HEITRONICS production meets the latest technical development thereby applying sophis-
ticated components. Nevertheless, functional errors may occur in exceptional cases. The
failure of an instrument may cause a measuring value being issued which seems to be
correct, but is wrong. Please pay attention to the instructions given in MAINTENANCE
AND CALIBRATION.
Only when using a female connector with cable or a dummy plug attached to the plug of
the device - in addition to the equipment sealing - the specified system of protection can
be achieved.
Operation with Laser: Devices completely mounted and equipped with integrated
laser meet the safety requirements of Laser class 2.
Before handling the lens in any way, the voltage supply is to be switched off or the
connecting plug is to be pulled out to ensure that the laser will not switch on automatically.
ATTENTION
The Laser must not be switched on, if the lens
of the Infrared Radiation Thermometer is removed.
The integrated laser cannot operate up to the upper limit of the ambient temperature
of the Infrared Radiation Thermometer (70 °C).
ATTENTION
The Laser will be switched off
at an ambient temperature ≥55 °C
to defend it from destruction.

2 GENERAL
2.1 Measuring temperatures using Infrared Radiation Thermometers
Above a temperature of absolute zero, which is approx. - 273 °C or 0 K, all bodies
emit electromagnetic radiation, the wavelength and density of which depend on the
temperature. Up to a temperature of approx. 600 °C, the wavelength of the radiation
can be found exclusively within the infrared range (thermal radiation). It is only at
higher temperatures where part of this radiation is emitted in the form of visible light.
The radiation emitted by the body (radiation density) also depends on the surface of
the individual body. At a fixed temperature, the maximum radiation density is emitted
by a "blackbody" source of radiation. All real bodies only emit a fraction of this radia-
tion density at the same temperature. The ratio of this fractional part to the maximum
radiation density is called the emissivity ε. Naturally, the emissivity is always < 1. It
depends on the nature of the surface of the material, on the material itself and on the
wavelength. If the emissivity is known, the temperature of the object can be deter-
mined by measuring the infrared radiation emitted by the very object.
Devices used to measure this kind of radiation are called Infrared Radiation Ther-
mometers.
As the measurement is effected without the Infrared Radiation Thermometer being in
contact with the object, no distortion of the temperature field due to heat dissipation
need to be feared, as is the case, e.g., with probe-type thermometers.
The Infrared Radiation Thermometer is a measuring transducer, which receives the
infrared radiation emitted by the measuring object itself and transforms it into a
standardized output signal.
All optic and electronic components are located in a small housing of a solid con-
struction, which is made from die-cast metal so that the installation of a Infrared Ra-
diation Thermometer is possible even in narrow spaces.
By selecting a number of various lenses and detectors, it is possible to generously
modify the measuring field, if the measuring distance is given.
For the application of the Infrared Radiation Thermometer under high ambient tem-
perature, water-cooling, air purge fittings and vacuum tight lenses can be delivered
as accessories.

2.2 Infrared Radiation Thermometers for GENERAL APPLICATION
The Infrared Radiation Thermometers series KT19.81 II, KT19.82 II, KT19.83 II are
used to measure surface temperatures within a temperature range of - 50 to
1000 °C. The spectral sensitivity can be found within the range of the atmospheric
window, which is between 8 and 14 µm. As the atmospheric transmissivity is very
high in this spectral range, no weakening of the infrared radiation due to CO2or to
water vapor contained in the air is to be expected.
To meet especially high requirements as to the transmission of the atmosphere (as it
is a case e.g. when carrying out meteorological measurements) Infrared Radiation
Thermometer KT19.85 II is suitable.
The KT19.81 II, KT19.82 II, KT 19.83 II can be employed in the measuring of tem-
peratures during the production and processing of plastics, rubber, paper, textiles,
paint, ceramics etc. The emissivity of various metals is shown in figure 10
(Ch. 7: Figures).
The devices can also be used to measure the temperature of objects exposed to in-
frared radiation, since the radiation maximum of infrared radiators is within the range
of shorter wavelengths, which do not cause the Infrared Radiation Thermometers
KT 19.81 II, KT19.82 II, KT19.83 II to react.
The Infrared Radiation Thermometer KT19.81 II is used in the spectral range of 8 to
10 μm. Besides being used for large-surface measurement, this Infrared Radiation
Thermometer type is also suitable for measuring thick foils.
The Infrared Radiation Thermometer KT19.82 II is applied for the standard measur-
ing range of 8 to 14 µm thereby guaranteeing a good signal resolution.

2.3. Infrared Radiation Thermometer for measuring METALS
The spectral emissivity of the Infrared Radiation Thermometer KT19.01 II, KT19.02 II
is 2 to 2.7 µm and 2 to 4.5 µm. Within this spectral range, metals and metal-oxides
show a relatively high spectral emissivity. This is why the device is particularly well
suited to measure the temperatures of these materials. Since the atmospheric trans-
missivity is high within the spectral range of 2 to 2.7 µm, distortions of the measured
value owing to absorption of water vapor and CO2in the air can be ignored
(Chap. 7: FIGURES, Fig. 11).
The Infrared Radiation Thermometer type KT19.01 II is used for measuring tempera-
tures from 300 °C onwards, the Infrared Radiation Thermometer type KT19.02 II is
suitable for measuring temperatures from 200 °C onwards. Temperatures from
500 °C respectively 700 °C onwards are preferably measured by means of
HEITRONICS Series CT18 or KT18RD.
2.4 Infrared Radiation Thermometers for measuring PLASTICS
These types of Infrared Radiation Thermometers are employed for the measuring of
surface temperatures of plastics within a temperature range of 0 to 600 °C.
These Infrared Radiation Thermometers are equipped with narrow-band infrared fil-
ters.
KT19.21 II measures radiation at 3.43 µm,
KT19.23 II measures radiation at 6.8 µm,
KT19.24 II measures radiation at 7.93 µm and
KT19.25 II measures radiation at 8.05 µm.
Within these spectral ranges, virtually all synthetic materials have strong absorption
bands so that even thin foils show high emissivity.
The Infrared Radiation Thermometer KT19.21 II is suitable for most foils from 100 °C
onwards.
The Infrared Radiation Thermometer KT19.23 II measures thin foils made from poly-
ethylene, polypropylene, polyisobutane, polynitrile, polystyrene and similar materials
from 0 °C onwards.
The Infrared Radiation Thermometer KT19.24 II and KT19.25 II measure thin foils
polyester as well as foils made from
- acrylic,
- cellulose,
- fluorine compounds,
- polycarbonate,
- polyamide,
- polyurethane,
- polyvinylchloride
and similar materials after analysis from 0 °C onwards.

2.5 Infrared Radiation Thermometersfor measuring GLASS
KT19.42 II is suitable for measuring glass and quartz. The spectral sensitivity is
4.9 to 5.5 µm. The emissivity of glass is very similar to the emissivity of a blackbody
radiator within this spectral range. Furthermore, this spectral range eliminates any
disturbing influences resulting from the strong absorption bands of water vapor at
6.2 µm.
The Infrared Radiation Thermometers KT19.01 II and KT19.41 II are not measuring
the surface but the average value of temperatures up to a certain penetration depth
(glass volume). The lower limits are 300 °C for KT19.01 II and 400 °C for KT19.41 II.
The types KT19.42 II and KT19.43 II measure the surface temperature from 100 °C
respectively from 0 °C onwards.
2.6 Infrared Radiation Thermometer for measuring GASES
By means of narrow-band filters, the selective measurement of temperature of cer-
tain gases is possible. A rather long response time is to be chosen since the radiation
energy is very low.
KT19.21 II measures hydrocarbon from 100 °C onwards.
The Infrared Radiation Thermometer KT19.61 II measures carbon dioxide,
KT19.62 II measures materials within the absorption range of carbon dioxide and
carbon monoxide,
KT19.63 II measures carbon monoxide selectively,
KT19.69 II has been especially developed for determination of combustion tempera-
tures from 400 °C onwards.
Using KT19.41 II, objects can be measured through gases and flames from 400 °C
onwards.

Technical Information
Protective Cooling Jacket
The HEITRONICS Infrared Radiation Thermometers can be operated at an environmental
temperature of up to 60 °C/ 70 °C 1without any additional coolants. If the environmental
temperatures are higher than that mentioned above, cooling fittings can be used.
Basically, the protective cooling jacket can be cooled with air or water. The possible
maximum environmental temperatures are higher for water cooling than for air cooling
(individual data sheets).
If the cooling process is too strong, i.e. if the cooling air / cooling water is too cold, this
may result in condensate at the protective cooling jacket as soon as cooling medium
falls below the dew point. To prevent this from occurring, the cooling air / cooling water
must have a minimum temperature as a function of the relative humidity.
The following table specifies the minimum temperature of the cooling air / cooling water
as a function of the environmental temperature and the relative humidity of the environ-
mental air.
