A250+ FO PL and A450+ FO PL are highly accurate monochrome digital fiber-optic pyrometers.
They are ideal for temperature measurement in demanding industrial and R&D environments.
They offer high performance and require little maintenance, as they measure without contact.
IR pyrometer parameters can be selected via the keypads on the rear panel.
Parameters are displayed on the OLED screen. In real-time measurement mode, the temperature is also displayed.
Pyrometers are equipped with RS-485; analog with 0/4....20 outputs.
Using or disabling the laser does not affect the measurement.
