Yes! LogTag data loggers have a unique serial number which is a prerequisite for individual calibration.
Every LogTag data logger is accompanied by a manufacturer's certificate confirming it meets published ex-factory specifications. In most cases this confirmation is sufficient. Certification beyond this is available in a laboratory of your choice.

The batteries used in LogTag data loggers last around 2 to 3 years, depending on usage (predominant temperature range, interval and frequency of download). To guarantee maximum reliability the batteries are soldered directly to the electronics, thus avoiding any contact issues otherwise arising from corrosion or mechanical and thermal shock.
You will require some basic technical knowledge to change the battery.

The software is essential to the use of LogTag data loggers. It is used to configure parameters such as logging frequency, start time, start type and others, and also to download and process the recorded data. You can, however, prepare the data loggers via the software to start at a given date and time, and once configured, an on-site start via a push button is also available.
The software is called LogTag Analyser and is available for free download in the 'support' section.

No! The memory contents of the data loggers can be overwritten many times, reset or deleted.

LogTag Analyser user interface language selections are Chinese, Czech, Danish, Dutch, English (UK), English (US), French, German, Greek, Italian, Norwegian, Polish, Portuguese, Romanian, Swedish, Spanish and Turkish. The user manual accompanying the software is available in English.

The user manual is accessible from inside the software. Selecting 'Help' - 'User Manual' will give you access to view or print a comprehensive and detailed manual. A short guide on how to install the LogTag interface cradle is part of the standard delivery or can be downloaded in the 'support' section.
