A data logger (also datalogger or data recorder) is an electronic device that records data over time or in relation to location either with a built in instrument or sensor or via external instruments and sensors. Increasingly, but not entirely, they are based on a digital processor (or computer). They generally are small, battery powered, portable, and equipped with a microprocessor, internal memory for data storage, and sensors. Some data loggers interface with a personal computer and utilize software to activate the data logger and view and analyze the collected data, while others have a local interface device (keypad, LCD) and can be used as a stand-alone device. Data loggers vary between general purpose types for a range of measurement applications to very specific devices for measuring in one environment or application type only. It is common for general purpose types to be programmable; however, many remain as static machines with only a limited number or no changeable parameters. Electronic dataloggers have replaced chart recorder in many applications. One of the primary benefits of using data loggers is the ability to automatically collect data on a 24-hour basis. Upon activation, data loggers are typically deployed and left unattended to measure and record information for the duration of the monitoring period. This allows for a comprehensive, accurate picture of the environmental conditions being monitored, such as air temperature and relative humidity. The cost of data loggers has been declining over the years as technology improves and costs are reduced. Simple single channel data loggers cost as little as $25. More complicated loggers may costs hundreds or thousands of dollars.

The supported Dataloggers in Credo5 are:

• KrautKramer DMS2
• 37DL Plus
• 38DL Plus
• Epoch 600
• Epoch LTC
• Epoch 3 (untested)
• Epoch 4 (untested)

A datalogger interface is available which can read from Dataloggers. The inspector will take his/her datalogger to the pipe location which is to be measured. They will place the probe against the pipe and take the thickness of that location. This is then recorded in a file alongside the details of that pipe location. The Credo datalogger device can then import this reading information against an existing Point, or a new Point can be created in Credo to store the imported data.
