The EasyLog EL-SIE-6+ is a high accuracy USB data logger designed for professional monitoring of temperature, relative humidity and atmospheric pressure. Built for demanding environments, it combines browser-based configuration, large onboard memory, configurable alarms and EasyLog Cloud compatibility, making it an ideal solution for reliable and traceable environmental monitoring.
With its integrated onboard software, there is nothing to install. Simply connect the logger to a PC or Mac using USB and access the interface through your web browser. This reduces setup time, simplifies deployment and improves usability in technical, industrial, laboratory and logistics applications.
The EasyLog EL-SIE-6+ is designed for organisations that require continuous environmental monitoring, reliable data logging and precise control of critical conditions. Its combination of stable sensing performance, large memory and intuitive configuration makes it an excellent choice for applications where compliance, quality assurance and operational safety matter.
This temperature, humidity and pressure data logger is suitable for a wide range of sectors where environmental stability is essential for products, processes or compliance.
All configuration and data viewing software is stored inside the product itself. Once connected via USB, the EL-SIE-6+ can be accessed through a standard browser interface, allowing users to configure settings, review readings, analyse data and download logs without installing local software. This simplifies onboarding and reduces IT dependency across professional environments.
Configurable parameters include logger and channel names, measurement units, logging rate, start modes, display behaviour, LED indicator modes and up to 16 independent alarms with thresholds, delay and hold functionality.
EasyLog Cloud allows logged data to be securely stored and accessed from internet-connected devices. This makes remote analysis, historical review and cross-team sharing far easier, especially for organisations managing multiple monitored spaces or locations. For businesses that value traceability, visibility and efficient environmental control, cloud integration adds clear operational value.
