Improper use
The device must not be pointed at people. Do not use the device
in potentially explosive atmospheres, for measurements in
liquids or at live parts. Trotec accepts no liability for damages
resulting from improper use. In such a case, any warranty
claims will be voided. Any unauthorised modifications,
alterations or structural changes to the device are forbidden.
Personnel qualifications
People who use this device must:
• be aware of the dangers that occur when working with
laser measuring devices.
• have read and understood the operating manual, especially
the Safety chapter.
Residual risks
Warning of laser radiation
Laser class 2, P max.: < 1 mW, λ: 650 nm,
EN 60825-1:2014
Do not look directly into the laser beam or the opening
from which it emerges.
Never point the laser beam at people, animals or
reflective surfaces. Even brief eye contact can lead to
eye damage.
Examining the laser output aperture by use of optical
instruments (e.g. magnifying glass, magnifiers and the
like) entails the risk of eye damage.
When working with a laser of class 2, observe the
national regulations on wearing eye protection.
Warning
Risk of suffocation!
Do not leave the packaging lying around. Children may
use it as a dangerous toy.
Warning
The device is not a toy and does not belong in the
hands of children.
Warning
Dangers can occur at the device when it is used by
untrained people in an unprofessional or improper way!
Observe the personnel qualifications!
Caution
Keep a sufficient distance from heat sources.
Note
To prevent damages to the device, do not expose it to
extreme temperatures, extreme humidity or moisture.
Note
Do not use abrasive cleaners or solvents to clean the
device.
Information about the device
Device description
The pyrometer BP17 uses an infrared sensor to measure
surface temperatures without contact. An integrated laser
pointer serves for the determination of the measuring spot.
For temperature measurements sensitivity levels of 1 °C, 3 °C
and 5 °C can be preselected – depending on a reference
temperature. Exceeding or falling below this preselected
threshold is indicated by an acoustic and visual alarm function.
The display is automatically illuminated during a measurement.
An automatic switch-off saves the battery.
Measuring principle
The device measures the temperature by means of an infrared
sensor. Important factors playing a role in the temperature
measurement are the measuring spot diameter and the degree
of emission.
Measuring spot
Observe the ratio of the distance to the measuring spot
diameter. The larger the distance to the object, the larger the
measuring spot diameter and hence, the less precise the
measured result. The connectable laser pointer indicates the
approximate measuring spot centre. Consequently, it is a mere
aiming aid and not intended for the actual temperature
measurement.
Degree of emission
The degree of emission is used to describe the energy radiation
characteristics of a material.
A material's emissivity depends on various factors:
• Material composition
• Surface condition
• Temperature
