The Optris CTi LT series pyrometers feature one of the world's smallest infrared sensing heads with an optical resolution of up to 22:1 and a spectral bandwidth of 8 μm to 14μm, ideal for high-emissivity targets even at low temperatures. With a wide temperature range from -58 to 1922°F (50 to 1050°C) , these pyrometers excel in non-reflecting object measurement. Their robust design allows operation up to 356°F (180°C) without additional cooling, making them optimal for high-temperature environments. Engineered in Germany, they offer precise non-contact temperature measurement with analog and digital outputs for seamless integration into machinery. Optional accessories, including mounting fork, sighting tube, close-focus lens, and air purge, enhance functionality, ensuring versatility across industrial applications.
