This Amprobe digital sound level meter offers two types of measurements: A and C weighting

Features & Applications:

This Casella digital impulse integrating sound level meter is a completely new design of integrating sound level meter featuring the power of Digital Signal Processing (DSP) technology and the simplicity and low cost of a traditional analog instrument. It can be used for a wide range of noise measurement tasks and is suitable for many everyday applications. Complying with all the ANSI and IEC accuracy specifications in the Type 2 category the CEL-244 will appeal to new and experienced users alike.

The new CEL-244 features a standard ¼” threaded socket on the back of the meter to allow it to be mounted on a tripod for fixed measurement applications. The meter is powered from 3 x AA alkaline batteries and will run for up to 35 hours on its own or continuously when powered from a mains-to-USB style adaptor or from a computer. Digital output via a USB mini A socket is available plus analog ac (or dc) voltage output through a 2.5mm jack socket to connect the CEL- 244 to other external computers or recorders

Applications:

The CEL-244 will be an ideal instrument for industrial hygiene measurements of noise in the workplace. The meter has a low and high measurement range that each covers a full 70dB. It can be used for machinery noise surveys as well as all general purpose workplace noise level measurements. With the A and C frequency scales and the S, F and I time response the meter can be used to assess the right hearing protectors using the NRR method. The non-decaying maximum hold and the integrated Leq/Lavg time average value of variable noises are displayed on the screen until reset by the user.

Features:

  • ANSI Type 2 accuracy
  • 30 to 130 dB total dynamic range
  • 2 x 70 dB measurement ranges
  • A & C frequency weighting
  • Slow, Fast and Impulse time weightings
  • Q=3 and Q=5 dB exchange rates
