Testo 184 T4 Cryogenic Temperature USB Transport Data Logger

Description

The Testo 184 T4 is a single-channel USB transport data logger specifically designed for monitoring extremely low temperatures during the transport of sensitive goods, particularly pharmaceuticals and blood plasma shipped with dry ice. It features a very low measuring range and can operate down to -80 °C. Unlike the short-term T1 and T2 models, the T4 has a user-replaceable battery, giving it an unlimited operating time for reuse. 

Key Features

• Cryogenic temperature monitoring: The internal Pt1000 sensor is engineered for extremely cold conditions, with a measurement range of -80 to +70 °C.
• Simple plug-and-play operation: The logger does not require any special software for setup or data readout. Simply connect it to a computer's USB port to access and customize the configuration file. After the transport, connect it again to automatically generate a detailed, tamper-proof PDF report.
• Built-in files: The logger comes with all necessary files stored directly on the device, including the configuration file, instruction manual, and calibration certificate.
• Unlimited operating time: The battery is user-replaceable, allowing the logger to be reused for many transports. The battery life is 100 days when operating at -80 °C with a 15-minute measurement cycle.
• Clear alarm indication: LEDs on the device provide a quick and clear visual alert if any temperature limit values have been violated during transport.
• High compliance: The T4 is compliant with GxP, 21 CFR Part 11, HACCP International, and EN 12830 standards, making it suitable for heavily regulated industries.
• NFC communication: Data can be transferred wirelessly via Near Field Communication (NFC) to a compatible Android smartphone or a Testo fast printer, enabling on-site data access.
• Durable and waterproof: With an IP67 protection class, the logger is dust-tight and protected against temporary submersion in water.
