A 250+
Temperature Range: 210°C to 3000°C
On-line Single Color Infrared Focusable Non-contact Pyrometers
A250+ is a highly accurate digital single color IR Focusable pyrometer to provide high performance and low maintenance of non-contact temperature measurement in demanding industrial and R&D environments.
The IR pyrometer parameters can be selected via the key pads on the back panel. The settings are displayed on the OLED Display. In the measuring mode real time temperature is displayed. In Pyrometers with video module real time colour video, measuring temperature and emissivity is displayed on the television screen.
A250+ has focusable optics for optimal match of the instrument for various applications. The pyrometers are equipped with RS-485; analog outputs 0/4….20mA. Switching laser ON/OFF does not effect the measurement.
