Metallic pyrometers from Advanced Energy Industries are advanced infrared and digital temperature measurement systems designed for non-contact monitoring of high-temperature processes.
Used across industries such as steel production, metal processing, glass, and ceramics, these pyrometers provide accurate, repeatable temperature readings in environments where traditional contact sensors fail. By eliminating physical contact, they enable safer, faster, and more reliable process control—helping manufacturers improve quality while reducing energy consumption and downtime.
The portfolio includes single-color, ratio (two-colour), fibre-optic, and modular pyrometers, covering extreme temperature ranges from sub-zero conditions up to 3500°C, with options tailored to specific materials and applications.

Range features
A high level overview of what this range offers
- Non-contact temperature measurement – Measure extreme temperatures safely without sensor wear or contamination, ideal for molten metals and moving targets.
- Wide Temperature Coverage – Solutions available from approximately -40°C up to 3500°C, covering everything from preheating to molten metal processes.
- High Accuracy & Repeatability – Advanced digital signal processing ensures precise and consistent readings, even in demanding environments.
- Ratio (Two-Colour) Measurement Technology – Reduces sensitivity to emissivity changes, dust, smoke, and dirty optics for more reliable measurements.
- Fast Response Times – Capture rapid thermal changes with response times as low as microseconds to milliseconds, ideal for dynamic processes.
- Flexible Optics & Spot Sizes – Fixed and focusable optics allow measurement of small or distant targets with high precision.
- Modular & Scalable Designs – Systems like the Impac 600 series offer interchangeable sensor heads and flexible configurations for diverse applications.
- Robust Industrial Design – Built for harsh environments with high ambient temperatures, dust, and vibration, ensuring long-term reliability.
