Cesva DC112a Dosimeter

Dosimeter (analyser in octave bands 1/1)

High performance instrument: Spectrum Analyser, Memory and USB port. Ideal for the measurement of noise according to OSHA, MSHA, NIOSH, ACGIH, DoD, etc.

Real time frequency analysis in octave bands (63 Hz to 8 kHz). 

Evaluation of exposure to noise with hearing protection 

Projection of parameters; evaluation of exposure to noise for measurement times shorter than the exposure time 

Great storage capacity; saves the time history of the measurement 

USB connectivity and power 

Dosimeter conforms to standard ANSI S1.25-1991 class 2 

Easy to program: double threshold level, exchange rate, criterion level, frequency and time-weighting 

Applications include: measurement of noise according to OSHA, MSHA, NIOSH, ACGIH, DoD, etc.


Main Features

The DC112 is a high performance dosimeter and the ideal instrument for measuring noise according to Directive 2003/10/CE. It is perfectly adapted to the regulation on the health & safety requirements, regarding the exposure of workers to the risks arising from noise.

The DC112 enables you to  simultaneously measure all the parameters needed to assess the levels of noise to which workers are exposed with and without hearing protectors (SNR, HML and Octaves). The DC112, besides measuring the equivalent level with A and C frequency weightings [ LAt, LCt ] (SNR and HML method), simultaneously carries out a real time frequency analysis, with or without, a frequency weighting and by octave bands from 63 Hz to 8 kHz (Octave method). And, of course, the Peak Level with C frequency weighting [LCpeak] is also available.

The DC112 enables you to assess and measure exposure to noise and also brings you all the data needed to inform and train workers with regard to the significance and potential risks arising from the results of the measurement and assessment.

Moreover, It helps you to design and run a reduction program and to choose the most suitable hearing protectors.

CAPTURE Studio is a comprehensive software application that allows you to: configure all the parameters of the instrument on just one screen, retrieve & display data from the instrument in real time (increasing the capacity of the registers because it is limited by the available memory of the PC), download registers from the instrument memory to a PC, erase the instrument memory (so the instrument will be empty & so you will have the full capacity to save the new measurements), display the data files graphically and numerically, convert them into different formats (.txt, .xls, .mdb), copy the graphic and numeric information supplied by the software (to create personalized reports) and save the files in its own *.ccf format (which then cannot be changed and guarantees their total integrity and legality).

CAPTURE Studio provides you with a convenient, easy-to-use environment for obtaining digital data acquired by the instrument.

CAPTURE Studio has been designed as a work environment for the new range of CESVA products. Software available for Cesva sound level meters, vibrometers and dosimeters.
