The Optris CTvideo 1M / 2M infrared temperature sensor uses both video and laser crosshair sighting to align sensors for accurate temperature measurements of metal or ceramic surfaces as small as 0.02 inches. Its short measuring wavelength of 1 or 1.6µm reduces errors when measuring surfaces with low or unknown emissivity. The sensor has temperature ranges from 482 to 3992°F (250 to 2200°C) and can be used in temperatures up to 158°F (70°C) without additional cooling .

Optical resolutions are 150:1 or 300:1 depending on the model. The sensor features a 1ms response time, 0.1K temperature resolution, and emissivity adjustable from 0.1 to 1.1. Adjustable focus allows precise targeting .

The sensor features a USB interface, peak hold, valley hold, average, and an extended hold function with threshold and hysteresis. Field selectable analog output options include 0/4-20mA, 0-5V, 0-10V, type K or J thermocouples, and alarm. It also features laser switch-off at 122°F (50°C) .

The Optris Compact Connect temperature analysis software is available as a free download. The sensor operates on 8-36 VDC power supply with 160mA max current draw and is IP65 NEMA-4 rated .
