Sound level measuring device SL300

This easy-to-handle sound level measuring device unites modern electrodynamic sound transducer technology and compact design.

As a sound level meter that complies with accuracy class 2 the SL300 is ideally suited for the documentation of machine and environmental noise as well as for workplace or noise hazard measurements.

The large four-digit measuring value display of the SL300 with additional bargraph presentation can easily be read in every environment thanks to the LCD background illumination.

With type A and C frequency weighting, fast/slow time weighting and many more practice-oriented functions this measuring device of the MultiMeasure Professional series is the perfect solution for demanding sound level measurements.

Its handy design, the light weight and the arrangement of keys optimized for single-handed operation make the SL300 the ideal basic equipment for standard measurements in the fields of industry, work and environmental protection.

SL300 – A user-friendly sound level measuring device with manifold possible applications:

  • Noise hazard measurements for occupational safety
  • Environmental protection applications for the determination of ambient noise
  • Determination of noise sectors for noise abatement measures in enterprises
  • Examination and selection of hearing protection devices
  • Auditing the adherence to noise protection regulations
  • Control measurements in air-conditioning and heating engineering

A few practical benefits:

  • Corresponds to accuracy class 2
  • Frequency weighting as per characteristic curves A and C
  • Maximum and minimum value memory
  • Storage space for 50 measured values
  • Reversible time weighting (fast / slow)
  • Display illumination
  • Bargraph display
  • 1/4-inch tripod thread
