Testo 835-T2 Professional High-Temperature Infrared Thermometer
The Testo 835-T2 infrared thermometer is an advanced, heavy-duty industrial pyrometer engineered for extreme thermal analysis up to 1500 °C. Specifically designed for critical manufacturing processes within the glass, ceramics, and metal melting industries, it allows specialists to track moving, highly heated, or structural assets safely from a distance. Featuring an outstanding 50:1 optical resolution and an integrated 4-point laser array, it perfectly maps the exact boundaries of the cross-section measurement circle over long distances. The multi-functional platform also features an external connection port supporting a wide variety of TC Type K contact probes for simultaneous core verification and automated material emissivity alignment.
Industrial Applications
- Metal Smelting and Foundry Control: High-precision thermal tracking of molten steel, furnace linings, casting units, and moving hot metal elements.
- Glass and Ceramic Kiln Diagnostics: Non-contact auditing of thermal distribution setups across critical structural firing chambers and melting pots.
- Heavy Infrastructure Maintenance: Long-distance tracking of high-risk thermal pipes, chemical reactors, and electrical refinery infrastructure.
