EasyLog | EL-21CFR-TC

21CFR-compliant Thermocouple Temperature Data Logger with USB


This 21CFR compliant, standalone data logger measures over 32,000 readings from inter-changeable J, K or T type thermocouples. Supplied with a K Type probe, its measurement range out of the box is from 0 to +200°C (-32 to +392°F). 

Used in conjunction with Lascar's 21CFR Part 11 software, the logger enjoys all of the core offerings of the original EasyLog software, but with additional 21CFR characteristics including user permissions, encrypted data which cannot be edited, full audit trail and electronic signatures for all activity.

Easily set up the logger and view downloaded data by plugging the unit into a PC’s USB port. Supplied with ½ AA battery and wall mount clip. 

PLEASE NOTE: You can add up to TWO SPARE BATTERIES for every data logger ordered.  If you wish to order more than this quantity, please contact your local sales office for special shipping information.
