Details

The pyrometer IGA 140/23-PN is a digital, highly accurate pyrometers for non-contact temperature measurement on metals, ceramics, graphite etc.

The PN types are equipped with a Profinet interface. They can easily be integrated in existing Profinet systems. As part of standard delivery, the GSDML file offers a selection of 5 different module configurations for varying requirements. The project planning can be done with any project tool.

For optimal match of the instrument to the application, 3 different focusable optics with extremely small spot sizes are available.

The pyrometer parameters can be selected via the integrated key pad, the settings are indicated on the built-in LC-Display. In measuring mode the actual temperature is indicated.

A laser targeting light, a thrulens view finder or a color camera module (for standard versions only) for exact alignment of the pyrometer is available.
