Details

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

The pyrometer are equipped with RS232 and RS485 serial interfaces (switchable inside the pyrometer). This enables additionally the reading of temperature and pyrometer parameters via the provided InfraWin PC-software. If necessary the parameters can be changed via PC.

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 or a thrulens view finder for exact alignment of the pyrometer is available.
