Optris PI 400i Online Infrared Camera | 382×288, 80 Hz, NETD 75 mK, -20–900 ℃ (1500 ℃ optional), IP67

Optris PI 400i Online Infrared Camera: 382×288, 80 Hz

Overview

The PI 400i (LT, 8–14 µm) is an online infrared camera in the Optris Precision Line. It connects to a PC via USB 2.0 and comes with the free PIX Connect software and SDK. The standard process interface provides a 0–10 V analog output, an analog input and a digital input; the optional industrial process interface adds 0/4–20 mA outputs and relays. The PI 450i in the same series has the same specifications but a NETD of 40 mK (60 mK with the 18° lens); it is available on request if higher thermal sensitivity is needed.
