Description

The compact Testo 174 T mini temperature data logger is a professional and highly cost-effective solution engineered for reliable continuous temperature tracking inside storage and transport infrastructures. Outfitted with a precision internal NTC sensor, it safely logs up to 16,000 readings across a broad span from -30 to +70 C. Highly optimized electronics secure continuous evaluation with a long-life operational battery span of up to 500 days. Crucially, your stored log dataset is protected by an unalterable backup profile and will never be lost when batteries are empty or being hot-swapped. It features a high-contrast display panel for quick local validation of limits alongside a robust IP65 waterproof structural frame, matching rigid international food safety compliance protocols.
