A 250C+
Temperature Range: 475°C to 1475°C
On-line Single Color Infrared Focusable Non-contact Pyrometers
A250C+ is a highly accurate digital two color 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, real time temperature is displayed. In Pyrometers, measuring temperature and emissivity is displayed on the television screen.
