When your process runs at temperatures that push equipment and operators to their limits, you need an instrument built for exactly that. The Raytek® Raynger® 3i Plus delivers accurate non-contact temperature measurement from 400°C to 3000°C with the optical resolution, operator safety features, and on-site data intelligence to handle the toughest conditions a foundry, steel mill, or petrochemical plant can throw at it.

Key Features:

✅Temperature range of 400°C to 3000°C across two spectral models with 1.0 µm and 1.6 µm for covering metals processing, ceramics, semiconductor furnaces, and petrochemical applications.
✅250:1 optical resolution for accurate measurement of small or distant targets from a safe operating distance.
✅Red Nose heat-resistant warning detector and audible alarm that alerts the operator the moment ambient temperature exceeds safe operating limits.
✅Dual laser and optional scope sighting with Red Dot technology visible even against red-hot, high-glare backgrounds.
✅On-site data analysis and trending with MAX, MIN, AVG, and DIF signal processing with real-time temperature trend display.
✅4,900 data point storage with location, date, and time stamp per measurement for full field traceability.
✅Ideal for iron and steel, foundry, ceramics, semiconductor furnaces, chemical and petrochemical, heat treatment, and power plants.

Aim. Read. Know. Stay Safe with the Raytek® Raynger® 3i Plus.
