The Optris CThot infrared thermometer is designed for high temperature environments. It can endure ambient temperatures up to 482°F without the need to additional cooling.IT is suitable for applications in dryers, ovens, heat treatment lines for metal and glass, and semiconductor processing. The Optris CThot includes D06ACCTMHS massive housing to stabilize measurements in applications with significant and short-term variations in ambient temperatures.

Selectable analog outputs and multiple digital interfaces offer high variability. Field selectable analog outputs options include: 0/4-20mA, 0-5 and 0-10 V, and type K or J thermocouples. The Optris CThot includes a programmable functional input for setting external emissivity, ambient temperature compensation, and reset of hold functions. It also features peak hold, valley hold, average, and an extended hold function with threshold and hysteresis. USB, RS485, RS232 interface, 2 optically isolated relay outputs, CAN-Bus, Profibus DP, and Ethernet available with plug in options.

The Optris Compact Connect temperature analysis software is available as a free download, and is necessary to document and analyze temperature measurement data. It is compatible with all netbooks, notebooks, and PC systems via Windows XP, Windows Vista, Windows 7 and 8.
