The NTM450 is an advanced high accuracy and repeatability pyrometer designed to operate as a stand-alone unit or in conjunction with the NTM500 emissivity independent pyrometer.
The emissivity for the temperature calculation can be entered directly from the NTM500 or via serial communication from a host computer.

Based on the state-of-the-art technology of the NTM500, it is a low-cost solution for in situ non-contact temperature monitoring in PVD, HDP-CVD, RTP and other processes. The NTM450 is a highly sensitive temperature monitor and allows temperature measurement from below 200°C.

• In situ, non-contact monitoring.
• Real-time emissivity input from external sources.
• Robust quick and vacuum-safe interface to the process chamber through quartz/sapphire light pipe and fiber optic bundle.
• Background compensation — built-in solutions to fit each OEM process environment, for full immunity to interfering radiation sources such as plasma or heating elements.
• Fast update rate, enabling use for closed loop control for all applications.
• Analog and digital outputs, to fit any host interface configuration.
• High sensitivity, resulting in low minimum temperature.
• Multi-probe operation (RS-485) with either NTM500 or NTM450.
• I/O compatibility to PDA's.
• Optional optical interfaces are available, including remote optics.
• Optional remote control unit with temperature display and emissivity input.
