Testo 175 H1 – Temperature & Humidity Data Logger
Testo 175 H1 – Temperature & Humidity Data Logger
The Testo Temperature & Humidity Data Logger is a compact, high-precision environmental monitoring instrument engineered for consistent climate tracking inside commercial buildings, industrial warehouses, and critical storage facilities. Outfitted with an internal thermal sensor and an external humidity stub sensor for accelerated response times, this dual-channel logging system tracks absolute temperature, relative moisture, and calculated dew points. It features an expansive internal non-volatile memory block storing up to one million individual readings, a long-term three-year operational battery life on standard cells, and a rugged IP54-rated structural housing built for durable field deployment.
Vendor: Testo

KEY FEATURES
- Dual measurements – internal temperature and external humidity sensor
- Fast reaction time with external humidity stub sensor
- Large memory for up to 1 million readings
- Battery life up to 3 years with standard AAA batteries
- USB and SD card interfaces for quick and flexible data transfer
- Free ComSoft Basic software for easy programming and analysis
- High data security – no data loss during battery changes
- IP54 protection class – durable for industrial and commercial environments
The Testo 175 H1 – Temperature & Humidity Data Logger delivers an elite technical framework for long-term indoor climate assessments, facility HVAC/R diagnostic reviews, and continuous warehouse storage auditing. While traditional internal loggers encounter tracking delays due to restricted housing airflow, the specialized external stub probe configuration on the Testo 175 H1 directly exposes the capacitive moisture element to ambient currents for near-instantaneous data stabilization. Technicians benefit from a large, clear front-facing LCD screen that communicates real-time measurements, active limit exceedances, and residual battery reserves at a glance. By ensuring absolute data safety during power cell replacement cycles and providing seamless export pipelines via an integrated mini-USB link or an optional SD card, this dependable logging module streamlines modern environmental compliance logging.
ADDITIONAL FEATURES
- High-accuracy NTC thermistor registers ambient temperature shifts down to a precise ±0.4 °C margin
- Premium capacitive moisture sensor delivers long-term stability with a minimal annual drift rate under 1% RH
- Large non-volatile memory architecture removes data loss concerns during multi-month logging cycles
- Free download of ComSoft Basic software enables rapid instrument programming and onsite CSV file parsing
- Flexible data evaluation pathways support structural expansion into ComSoft Professional or CFR 21 Part 11 suites
APPLICATIONS
- Perfectly optimized for continuous indoor climate monitoring, ambient temperature tracking, relative humidity verification, and automated dew point tracing across commercial offices, industrial warehouses, cold storage facilities, and high-density manufacturing zones.
