📈 21CFR USB Thermistor Probe Logger

Key Features

✅ High-accuracy thermistor sensing from −40 °F to 257 °F
✅ USB interface for quick data download and archiving
✅ LCD screen for real-time viewing and Min/Max values
✅ Wide programmable logging rate from 1 sec to 12 hrs
✅ Compact, lightweight design with 3M adhesive backing
✅ Ideal for labs, storage, processing, and QA applications

This high accuracy standalone data logger measures and stores more than 32,000 temperature readings over a -40 to +125°C (-40 to +257°F) range with a resolution of 0.1°C (0.2°F). The user can easily set up the logger and view downloaded data by plugging the data logger into a PC’s USB port and using the free EasyLog 21CFR software. Data can then be graphed, printed and exported to other applications for detailed analysis. The encrypted data has full audit tracking to comply with the requirements of 21CFR Part 11.

The high contrast LCD can show a variety of temperature information. At the touch of a button, the user can cycle between the current, maximum and minimum stored values for temperature.

The data logger is supplied with a lithium metal battery which typically gives two years’ logging life.

WHAT IS 21 CFR PART 11?

Normally when using environmental recorders consisting of hardware, sensors and software, the data is collected and stored in various means. To comply with 21 CFR Part11 the entire data processing has to be validated to make sure that there is no data corruption through the entire process.

21 CFR Part 11 is confirming the instruments information / data digital signature. To ensure that data generated by a software and/or recording devices have not been voluntarily or involuntarily altered/modified. It details several points that a organizations must implement before stating its solution is 21 CFR Part 11 compliant by generating a PDF file that cannot be modified, certify that data are encrypted, software must have an ID and password to login, audit trail and the instrumented and sensors are validated/certified/traceable.

This standard is usually known and requested in the life science industry. If you want to rely on loggers to certify that pharmaceutical products are correctly maintained within their proper range of temperature, you have to make sure that data generated is reliable.

The purpose of 21 CFR part 11 is basically to ensure that the data read and stored by a software and environmental instruments are entirely accurate.
