Testo 174 T Black Mini Temperature Data Logger with USB-C
The Testo 174 T black mini temperature data logger is a highly precise, single-channel thermal recording instrument engineered for HVAC/R inspection, food storage, and industrial maintenance. Designed for continuous temperature monitoring, it safely archives up to 16,000 readings within an operational window spanning from -30 °C to +70 °C. Data extraction is managed seamlessly via an integrated USB-C data communication port paired with the ComSoft Basic desktop configuration system, enabling quick asset tracking and structured Excel export reporting. Featuring non-volatile internal storage, it guarantees automatic data backup during complete power exhaustion or element maintenance.
Industrial & HVAC/R Applications
- Cold Chain Logistics: Continuous thermal profile tracking inside distribution hubs and cold freight units to maintain compliance.
- HVAC/R System Commissioning: Efficient monitoring and fault diagnosis of heating, ventilation, and air conditioning line temperatures.
- Facility Microclimate Documentation: Unobtrusive long-term ambient temperature logging across commercial property units and archives.
