Testo 175 T2 Professional Dual-Channel Temperature Data Logger
The compact Testo 175 T2 temperature data logger is a professional monitoring instrument engineered for simultaneous tracking of air temperature and product core values. It features one internal NTC sensor to map ambient climate conditions and one external probe connection channel for flexible spot checks (such as package gaps or food core penetration). Designed for intensive operations within food processing, gastronomy, and cold chain logistics, this logger features an extensive memory block holding up to 1 million measuring values and an outstanding battery life of up to 3 years. The heavy-duty housing carries a fully certified IP65 ingress protection rating, allowing the hardware to remain inside deep-freeze rooms or cold storage areas even during wet clean-down cycles. It is fully HACCP-compliant and rigorously certified according to the international EN 12830 standard for maximum data safety.
Industrial & Logistical Applications
- Cold Chain & Food Storage Monitoring: Parallel tracking of ambient room air conditions and internal core temperatures of food goods in warehouse sectors and cold stores.
- Deep-Freeze Room Diagnostics: Continuous non-destructive thermal logging inside extreme freezing setups down to -35 °C.
- Supermarket Asset Auditing: Quality control logging at critical control points (CCP) including open display cases and logistics cargo gaps.
