Raytek

Raytek

Raytek is a brand specializing in non-contact infrared temperature measurement, best known for the Raynger series of portable infrared thermometers. Raytek instruments are engineered for industrial environments where contact-based measurement is impractical or unsafe — including rotating machinery, electrically live components, and surfaces at extreme temperatures. Their thermometers feature adjustable emissivity, built-in laser sighting, and wide temperature measurement ranges to serve diverse industrial applications.

The Raynger 3i Plus series represents the professional tier of Raytek's handheld lineup, offering high optical resolution and optional scope sighting for precise spot temperature measurement at distance. Raytek also offers fixed-mount infrared sensors for integration into continuous process monitoring and control systems.

Key Product Lines

• Raynger portable IR thermometers — handheld non-contact instruments with laser targeting and adjustable emissivity for field and maintenance use
• Fixed-mount infrared sensors — for continuous process temperature monitoring with control system integration

Industries Served

Raytek instruments are widely used in predictive and preventive maintenance, industrial manufacturing, HVAC systems, food and beverage processing, plastics and rubber production, electronics manufacturing, and automotive assembly. Non-contact measurement capability makes them essential tools for electrical panel inspection, furnace and kiln monitoring, and any process where direct sensor contact is infeasible or hazardous.
