BEST IN ADVANCED FEATURES
The temporal redundancy improves the reception’s reliability of measures, at an optimized
energetic cost. If the radio signal is weak, it allows the transmission of a reminder of the
previous measures with the new physical measures in successive radio messages.
The flush mode allows to accumulate up to 10 days of temperature data recording, when
the network is not available. The Senlab T will transmit them as quickly as possible when
the network is available.
Advanced monitoring mode allows the data to be monitored up to every second. An alarm
can be triggered if the temperature rises within a given time period. This mode can be
activated in parallel with the classic operating mode.
