A data logging system does not need to be prohibitively expensive as many of our data logging systems can utilise pre-installed equipment and even your existing PC or laptop. We can record any process or electrical variable you wish.

One of the primary benefits of using data loggers is the ability to automatically collect data for long periods of time without the need for any operator intervention such as having to change a paper chart or pen. Upon activation, data loggers are typically deployed and left unattended to measure and record information for the duration of the monitoring period. They are particularly suitable for monitoring environmental conditions during shipping, transport or storage of temperature sensitive items.
