2.1.1 – Application Fields:
The instrument for its characteristics is very flexible and easy to be used, then it is proper for a general use and we indicate
some typical application:
- Industrial Sector
- Food Sector
- Seasoning
- Painting
- Security and Firing prevention Sector
- Plastic moulding and plastic materials working
- Asphalt Working in Covering & Street Applications
- Typographic and Packaging Sector
- Food Cooking and Drying
- Service Sector
- Electric Installation and Servicing
- Building Sector
- Insulating Materials Installation and processing
2.1.3 – Optical Ratio (Optical Vision Field @ of the Infrared measure):
F324 is a combo thermometer, which serves then to measure the temperature, but differently form other kind of
thermometers, this kind of instrument thanks to its technology succeed in making the measurement both in a traditional way
with a thermocouple and without physical contact with the product to be measured, this is possible thanks to the particular
used technology, which is based on the survey of the infrared radiation inside a specifically frequency range, also called
wavelength, which all bodies plus or minus emit in function of their nature and of the temperature they are.
The instrument “catches” these radiations, invisibles to the human eye, through a special electronic sensor, and thanks to a
powerful circuit provided by a micro-processor, able to make complex calculations, it converts the radiations in a precise
temperature measure.
Then as it should be clear, the instrument act itself as an optical “Passive” device, with a result that the major will be the
distance between the instrument and the Target (Target = Point of Measure) and major will be the dimension of the SPOT
and vice versa, as explained in the below graphic example.
Attention: the two laser rays visible during the measurement are only the pointer which makes easier the estimate
individuation of the point and of the measurement area, they don’t have any function in the measurement, it is very important
keeping in mind this detail, because it can be to find a case in which making for instance a measurement through a glass, the
laser will pass through it, letting you think the measurement is through the glass, while in reality the infrared measurement
will be on the surface of the glass, this detail is explained by the fact that on the operative Laser frequency, the glass is
transparent, while on the thermometer infrared wave length the glass is absolutely opaque, that means impenetrable.

2.1.4 - Emissivity:
The correct conversion of the infrared radiation in a temperature value is made by mathematical formula (Law of PLANCK)
which for a correct conversion, asks the set up of a constant called “Emissivity” which changes in function of the kind of
material we are going to measure, the emissivity of the instrument described in this manual, is changeable from 0.10 up to a
1.00
