SFTL Software

SFTL04 is a comprehensive software application that allows users  display numerically and graphically data registered by LRF-04 and choose the displayed interval, program all the parameters from the LRF-4, generate reports of the data supplied by the software, personalize these reports by writing a maximum of 50 characters as a footnote, study in detail all the sound levels and incidences, acquire data via Modem, display, in real time, the data measured by the LRF-04, program all the parameters of the LRF-04 on just one screen and erase the LRF-04 memory.

  • SFTL04 shows the Time History data and the time representation of incidences, this way it is possible to study, in detail, what happens in the establishment, the sound levels produced, if the sensor has been tampered with and when.
  • SFTL04 provides you with a convenient, user-friendly environment for obtaining, in digital format, data acquired by the LRF-04.
