The post HD2024C – Class 1 Sound Level Calibrator appeared first on Senseca.

]]> The HD2024 sound level calibrator is a portable, battery operated sound source, suitable for sound level meters (portable and laboratory) and acoustic stations.

It allows calibrating 1/2” (1/4” with HD2020AD4 adapter) microphones with mechanical dimensions compliant with IEC 61094-1 and IEC 61094-4.

The generated sound pressure level is equal to 94 dB at 1000 Hz frequency. A LED signals the low battery condition.

Advantages of the HD2024 calibrator:

  • The 1000 Hz frequency allows calibrating sound level meters with any frequency weighting (LIN, A, B, …), without applying any correction factor.
  • The generated sound pressure level is indipendent of atmospheric pressure: you don’t need to adjust the value according to static pressure over a wide range of values.
  • Its simplicity of use allows even unskilled staff to use it.

It includes ISO17025 Calibration Certificate.

The post HD2010UC.kit2 – Class 2 Integrating Sound Level Meter appeared first on Senseca.

]]> The HD2010UC.Kit2 is a Class 2 integrating portable sound level meter performing statistical analyses. The instrument has been designed combining price competitiveness and simplicity of use. Attention has been paid to the possibility of updating the instrument, and the HD2010UC can be integrated, at any time, with other options like “Advanced Data Logger” to extend its application scope.

The firmware can be upgraded directly by the user using the NoiseStudio program supplied with the instrument.

The HD2010UC conforms to IEC 61672-1 of 2002 and IEC 61672-1 ed. 2.0 of 2013, IEC 60651 and IEC 60804 specifications with class 2 or class 1 tolerances.

The instrument is suitable for the following applications:

  • Assessment of the environmental noise level,
  • Occupational noise measurements at the workplace (according to ISO9612)
  • Selection of personal protective equipment,
  • Production quality control,
  • Measurement of machine noise.

With the optional “Advanced Data logger” function the sound level meter is able to perform the following task

  • Environmental noise monitoring,
  • Analysis of sound events,
  • Complete statistical analysis with percentiles calculation from L1 to L99.

Kit includes: Sound Level Meter HD2010UC Class 2, 1/2” UC52 pre-polarized condenser microphone, windscreen, preamplifier, USB or RS232 cable, carrying case, declaration of conformity, Noise Studio basic software version.

For Class 1 see HD2010UC.kit1.
