BL30 Climate data logger

Simple and exact long-term recording of environmental data

Autonomous long-term recording of climate data

The BL30 is an ultra-compact climate data logger for the long-term recording of air temperature and relative humidity in living, work or storage spaces. For stationary use a lockable wall mount is included in the scope of delivery.

The combination of large memory for 32,000 measured values, a freely adjustable saving interval ranging from 1 second to 24 hours per recording and the alarm function with logging of freely definable upper and lower alarm limits allows innumerable possible applications of the BL30 – e.g. as mandatory test verification for craftsmen, for the cause assessment of damages caused by moisture or mould in rental flats or for the documentation of consistent climate data in archives and storage facilities.

The supplied PC analysis software comes with evaluation and documentation functions for all measured values including time and date as well as alarm incidents.

Since the BL30 is exclusively configured via PC, a manipulation of the configuration by unauthorized persons directly at the measuring device is impossible.

Depending on recording interval and surrounding conditions, the durable battery of the BL30 enables autonomous readiness for use over a period of several months.

All software advantages for you in the video overview

By the way: The BL30 climate data logger can also be analysed and configured using the freely available MultiMeasure Studio Software (Standard Version). The optionally available MultiMeasure Studio Professional Version additionally allows, among other things, for the export into an Excel sheet format and the creation of automated reports for a corresponding evaluation.
