Description

The premium Testo Saveris 2-T3 WiFi data logger is an advanced stationary solution engineered for automated long-term temperature tracking in heavy industrial processes and thermal units. Outfitted with 2 connections for external thermocouple probes (TC Types K, T, J), it achieves an ultra-wide measurement span covering -200 to +1350 C depending on the probe setup. It streams measured profiles automatically via wireless LAN (WLAN) using the standard MQTT protocol to the centralized Testo Cloud system platform. The logger incorporates a built-in LCD showing current readings, battery indicators, and target boundary breaches locally, protected by a robust IP54 layout housing. Critical parameter violations trigger immediate real-time automated notifications via email or high-priority SMS alerts.

Industry Applications

• High-Temperature Process Audits: Tracking extreme thermal curves inside industrial baking ovens, smelting setups, and technical melting cells via long-line thermocouples.
• Sub-Zero Logistics & Cryogenics: Monitoring deep-freeze storage tanks or liquid nitrogen installations using specialized low-temperature Type K or T lines.
• HVAC Systems & Boiler Monitoring: Simultaneous dual-channel input monitoring of feed and return fluid temperatures in heating networks.
