A250 FO-PL

Part Code: A250 FO-PL



A250 FO-PL & A450 FO-PL are highly accurate digital Fibre Optic industrial IR Pyrometers, for non-contact temperature measurement in demanding applications.

The Fibre Optic Pyrometers are widely used in high ambient temperature applications without cooling and also in processes involving electromagnetic interferences. With a very short response time of <2ms the pyrometer is capable of measuring the fastest heating processes.

The Pyrometer is provided with Bluetooth V2.0 for communication between pyrometer & android mobile, RS-232 & RS-485 for communication between Pyrometer & PC software. The parameters such as Emissivity, Response time, Analog output, Subrange, Peak picker can be adjusted remotely via PC software.
