  • Brand: Castle

World's first “0-dB measurement-function”

By employing the original DSP technology, which eliminates the self-noise of the microphone with preamplifier, the lower limit of measurement has been drastically extended to lower than 0 dB-SPL. Linearity range, extended to 100 dB in the usual state, further expands to that corresponding to the measurement range 80dB(A) by holding the 0-dBfunction in ON position.It enables to measure ultra-low sound pressure level, so displaying its greatest power as inthe quietness measurement of, or tone quality evaluation of, various silent-type IT/O equipments, as well as in the measurement of air-conditioning noise or sound isolation in a concert hall with ambient noise below NC-20.

Castle Sound Level Meters Specification for Castle 6224 (Class 1)

Measuring noise really does not have to be complicated, even for the novice, and the Castle 6224 (Class 1)Integrating sound level meter is designed with this in mind.The meter is ideally equipped for carrying out Noise at Work Risk Assessments, as well as the majority of environmental survey work. The range of parameters measured, the wide measuring capability of the meter and the ease of use, mean that this equipment is suitable for anything from aircraft noise to lawnmower design, and from construction sites to laboratories.Noise at Work Measurements The Castle 6224 provides the essential measurements required by the Control of Noise at Work Regulations2006, including Leq (equivalent continuous level) in ‘A’ and ‘C’ weightings, and Cpeak. The meter candata-log any of these parameters in up to 10,000 data-memories, making it more than powerful enough for the task in hand.Environmental Monitoring Also ideally suited to environmental monitoring, the Castle 6224 can measure 5 selectable percentile values and sound exposure (LE). Most environmental measurements require Leq and L90 plus possibly one or two other measurements. These can all be measured simultaneously with the Castle 6224 and data-logged into its 10,000 data-point memory.Multi-purpose Measurement Many sound measuring tasks require the measurement of Leq (equivalent continuous level), Lmax (Maximum rms level), LE (Sound Exposure) or percentiles,and all of these can be completed using the Castle 6224 with its accessories.Operation The Castle 6224 (Class 1) Integrating Sound Level Meter has an easy to follow menu system and clearly marked keys, all designed to make the meter simple-to-use. The back-lit LCD display is also very clear with large figures and a quasi-analogue display bar to show the changes in sound level as they happen.

• Equivalent continuous level (Leq)
• 5 user selectable percentile values (Ln)
• Wide Linearity range of 90dB
• RS232 for data output to optional software
• Memory storage for 10,000 datapoints
• Back-lit LCD display

Sound Level & Noise Exposure Meter

Sound Level & Noise Exposure Meter

There are a number of system packages available to suit many applications from simple tasks such as alarm monitoring, to a fully weatherproof system for long-term environmental solutions, there are also dedicated packages for Noise at Work requirements.

The flagship model of the Pocket Sonus Meter range is the class one Sonus GA116L which is a full data logging, integrating sound and noise exposure meter (dose meter) which has been designed for both Noise at Work assessments and Environmental Sound monitoring.

Simply unplug the sound meter pre-amplifier and plug in the dose meter cable which is available as an optional accessory to convert to a fully functional dose meter.

It has the capability to combined sound and dose meters with time and date stamped data logging.

The meter features dual measurement, so two versions of most parameters can be measured simultaneously. This feature means you only need to measure once and for Noise at Work assessments you’ll have the correct parameters recorded to determine suitable hearing protection using the HML method, a function available in dBdataPro software. Connectivity is via high speed USB and the meter ships with free noise analysis software dBdataPro-Lite and download cable.

Features :

  • Measures Lp, Leq, Lmax, LE, Pa2h, Lep’d, Dose,
  • Dose Per Hour, L10, L90, L(user)
  • Measures parameters simultaneously including LAeq and either LZeq or LCeq
  • Under range and Overload indicators
  • Hearing Protection using the HML method
  • User selectable Exchange rate, Threshold and Criterion level.
  • User Modes: Noise at Work, Environmental or ALL
  • A, C or Z frequency weighting selection
  • A, C or Z Peak Measurements
  • ‘Slow’, ‘Fast’ and ‘Impulse’ time weighting selection
  • Save results to internal flash memory
  • Download data to a PC via a USB connection
  • Noise Analysis Software included with the meter
  • Small and light weight, fits into small shirt or jacket pocket and also supplied with a strong pocket clip.
  • Lockable Key pad through options
  • Single battery operation of typically 12 hours
