Functional description
The pyrometer BP21 uses an infrared sensor to measure surface
temperatures without contact. An integrated dual laser pointer
can be switched on for the precise determination of the
measuring spot diameter. Additionally, the degree of emission of
the material to be measured can be set. The device can show
either the maximum or minimum value of the measurement.
The device further features an alarm function. When exceeding or
falling below the specified values, the device emits an acoustic
signal.
The display can be illuminated as needed.
When not in use, an automatic switch-off saves the battery.
