Casella USA has introduced some new additions to
their popular range of personal noise dosimeters. The new CEL-320IS and
CEL-360IS compliment the existing range of lightweight units that have been
currently available. Now the IS CEL noise dosimeters can be used where there is
concern due to the hazardous nature of the environment. The dosimeters carry the
IS approval ATEX EEx ia I M1 corresponding to EEx ia T4 II 1 G certificate
number 05ATEX2027X. The dosimeters will appeal to users to measure noise
exposure in many mines, printing works, chemical and petrochemical plants and
other similar locations where there is concern about high noise levels.
Both new instruments feature preprogrammed setups
ready for the user to simply switch on and start recording without having to
worry about choosing the right parameters. Pre defined named setups allow for
easy measurement of noise in the workplace according to OSHA, MSHA, NIOSH and
ACGIH requirements.
The CEL-320IS and 360IS will measure the actual noise
dose, the 8-hour projected noise dose using either 1 or 2 thresholds with the
appropriate exchange rate of 3, 4 or 5 depending on the setup selected. The time
average level plus the TWA are computed for both 8 hours and a user selectable
workday if other than a standard day. Maximum, minimum and peak levels are
captured for an accurate and comprehensive picture of the noise exposure.
The CEL-360IS is also a data-logging unit and will
allow the user to store up to almost a quarter of a million time history data
points for a better understanding of the variation of the noise levels over the
measurement time. This allows the efforts for noise control to be concentrated
in the periods of highest noise exposure so that they are most cost effective.
The CEL360IS also features a comprehensive set of
delay timers that can be made to control the collection of noise readings
automatically up to 1 month in advance. Manual collection of noise data is also
possible for variable or fixed periods of time right from the keypad of the
dosimeter.
The CEL-320IS and 360IS noise dosimeters are provided
as complete kits including a matching acoustic calibrator and powerful download
software. Single kits and 5 and 10 packs are available to suit the customer’s
requirements for a comprehensive noise evaluation program.
Casella USA is also able to offer
instrumentation for personal dust sampling, VOC gas sampling, area dust sampling
as well as heat stress and all forms of noise measurements.
