The pyrometers IS 5 and IGA 5 are digital, compact and fast infrared measuring instruments for non-contact temperature measurement on metals, ceramics or graphite.

For optimal match of the instrument to the application 2 different optics with extremely small spot sizes are available. The response time of only 2 ms facilitates the measurement of fast heating processes or short temperature peaks.

For a precise alignment of the pyrometers to the measuring object, the instruments are optionally equipped with a laser targeting light, a view finder or a video module. The most important parameters as emissivity, exposure time and analog output can be set directly in the instrument. Additionally the pyrometer can be connected to a PC via serial interface, enabling adjustments of further parameters with the delivered software InfraWin. This can be used for temperature indication, data logging and further analyzing of complete temperature processes.
