Testo 175 T2 temperature data recorder

The testo 175 T2 temperature data logger has an internal sensor and a connection for an external temperature probe.

Reliable dual-channel temperature monitoring for food and pharmaceuticals

Dual temperature measurement

The testo 175 T2 records both ambient air temperature and the temperature of goods with an optional external probe. This makes it ideal for cold storage, processing areas, and quality checks in food and pharmaceutical industries. Measurements can also capture temperature inside packages, ensuring product safety and compliance.

High-precision sensors

The internal NTC probe delivers ±0.5 °C accuracy across a range of -35 °C to +55 °C. Optional external probes expand the measuring range up to +120 °C depending on the model, making the logger suitable for deep-freeze or high-temperature applications. Data from both channels is securely stored in the device.

Clear on-device display

The display shows current values, min/max readings, limit violations, and battery life, allowing users to monitor conditions without connecting to a PC. This reduces the frequency of data downloads for shorter measurement cycles.

Long-term data storage and reliability

With memory for up to 1 million readings and a battery life of up to 3 years, the testo 175 T2 ensures secure data retention. Standard AAA batteries are user-replaceable, and stored data remains safe even during battery changes.

testo 175 T2 logger with internal NTC probe and external probe connection, wall bracket, lock, batteries, and calibration protocol. USB cable for programming not included but can be ordered separately. Data transfer to PC is possible via USB or optional SD card.

Applications

Monitoring and documenting cold storage temperatures

Essential for foodstuffs and medicines that must remain within strict temperature ranges, the logger is placed at critical control points (CCPs) to detect fluctuations and ensure compliance with quality regulations.

Monitoring frozen storage areas

Used in freezer rooms at small manufacturers, restaurants, supermarkets, or large cold storage facilities. EN 12830-compliant, the logger records air temperature at key locations like doors or refrigeration units, enabling analysis and long-term storage of data.

Ensuring proper storage conditions

By automatically tracking ambient temperature, the testo 175 T2 helps maintain product quality in food and pharmaceuticals. Alerts for limit violations allow rapid responses, and software enables detailed analysis of recorded data.

Transit temperature monitoring

Maintaining the correct temperature during transport prevents product spoilage and quality loss. The data logger allows continuous monitoring of goods in transit, with data easily read, analyzed, and stored via compatible software. Data Sheet

Q&A
