Data Loggers:

Environmental Recorders

Hanwell’s data loggers are perfect for standalone, hand-held or even transportation and storage monitoring. Each data logger reads its on-board sensors to provide accurate and reliable information about the relevant environmental conditions. The historical data can be downloaded from the unit using an integrated software package, and connected to a local PC via a USB lead.



Data loggers are ideal for quick and easy use time and time again.

We pride ourselves in our ability to accurately interpret customer requirements. If you require the monitoring of any parameter not mentioned below, please call as we will, almost certainly, have a solution for you.
