Part Code: A450C+SPPL



A450C+ is a highly accurate digital two-colour IR Focusable pyrometer to provide high performance and low maintenance of non-contact temperature measurement in demanding industrial and R&D environments. The Pyrometer measures the temperature of an object by calculating the ratio of the energies at two different wavelength bands. The ratio technique eliminates and reduces errors in temperature measurement caused by changes in Emissivity, Surface finish and energy-absorbing materials such as Water vapour etc.
The IR pyrometer parameters can be selected via the keypad on the back panel. The settings are displayed on the OLED Display. In the measuring mode, the real-time temperature is displayed. In Pyrometers with temperature and emissivity is displayed on the rear display screen. A450C+ has focusable optics for an optimal match of the instrument for various applications. The pyrometer is
equipped with RS-485 output; analog outputs 0/4….20mA. Switching laser ON/OFF does not affect the measurement.
