Ctemp AA

C\TEMP-AA Single-Use Temperature Data Logger

Durable | NIST-Traceable | Multi-Language Support

Built for demanding cold chain applications, the C\TEMP-AA Single-Use Temperature Logger is a compact, pre-programmed device ideal for tracking temperature conditions during the transport of produce, chemicals, pharmaceuticals, vaccines, and dry ice shipments. Developed by Marathon Products, this rugged large-format logger features extended battery life for challenging transit environments.

The internal digital thermistor accurately records temperature in Celsius, Fahrenheit, or Kelvin, with a range -29°C to +72°C. The device provides real-time temperature readings, alarm status, and logging activity. Starting the device is simple—just press the button.

The firmware stores key tracking data, including start time, sampling intervals, alarm conditions, and device identifiers. For international usability, the multi-language interface allows real-time switching between English, Spanish, Portuguese, Japanese, French, and German.

Each unit is NIST-traceable and includes a Certificate of Conformance, ensuring regulatory compliance for temperature-sensitive goods.
