Sound Level Meter Measurement Kits
The CR800C series can be supplied in a measurement kits which
include all of the accessories required to operate the instrument.
A measurement kit is the recommended way to purchase a Sound
Level Meter as it also contains a suitable Acoustic Calibrator. All
noise measurement equipment should be calibrated regularly to
ensure that it is operating and measuring correctly.
The standard measurement kit
includes the following components:
>
CR515 or CR514 Acoustic
Calibrator
>
UA237 Windshield (90mm)
>
CK250 Carrying Case
>
Deaf Defier Software
>
USB Data Cable
>
Operating Manuals
>
Certificates of Calibration
>
Batteries
The measurement kits for the the Class 1 Sound Level Meters
(CR811C, CR813C, CR821C & CR831C) are supplied with the
Class 1 CR515 Acoustic Calibrator. The Class 2 Sound Level
Meters (CR812C, CR822C and CR832C) are supplied with the
CR514 Class 2 Acoustic Calibrator.
The CK250 Carrying Case can also hold a microphone extension
cable and protects the Sound Level Meter and Acoustic Calibrator
from damage during transit and storage.
Weatherproof Outdoor Measurement Kits
Where measurements are to be made outdoors, the Sound Level
Meter should be protected from rain and wind.
If the measurements are to be made over a short
period, and the weather conditions are fine, the
Sound Level Meter can be mounted on a tripod,
and the UA237 Windshield used to reduce wind
induced noise.
If the measurements are to be made over a
longer period, or if the weather conditions cannot
be guaranteed, an Outdoor Measurement Kit
should be used. The CR800C series can be used
with two different Outdoor Measurement Kits, the
CK408C and CK508C.
Both of these kits provide
a secure, weatherproof
enclosure for the Sound
Level Meter and the
microphone as well as a
rechargeable battery pack
to power the sound level
meter.
The CK508C Lightweight Outdoor Kit has been designed to be
used for short term measurements, such as overnight, whilst the
CK408C Outdoor Kit has been designed for longer term use.
The Weatherproof case used for both of the outdoor measurement
kits contains the same accessories included in the standard
measurement kit. Space is provided to
hold a sound level meter, acoustic
calibrator, a standard 90mm windshield,
software CD, batteries and operating
manuals.
Please note that Class 2 versions of the
CR800C require the MO800/5 Remote
Preamplifier option before they can be
used with the Outdoor Measurement
Kits.
GSM Cellular Modem Option
In situations where an outdoor
measurement kit is used, it is
often useful to be able to
access the measurement data
stored by the instrument from
a remote location.
To allow for this, the outdoor
measurement kits can be
fitted with a GSM Cellular
Modem. When this option is fitted, the Deaf Defier software can
connect to the sound level meter and download measurement data
over a GSM network. External power can be connected to the
outdoor kit to allow the instrument to run for longer periods.
Safety Officer’s Noise Measurement Kits
The CR800C Sound Level Meters are also available as part of a
Safety Officer’s Noise Measurement Kit.
These kits provide a complete noise measurement solution and
include a sound level meter along with a number of the Cirrus
doseBadge Personal Noise Dosemeters.
The sound level meter can be
selected from any of the
CR800C range to meet the
needs of the user. The
doseBadge units can be either
t h e s t a n d a r d C R 1 1 0 A
instruments or the Intrinsically
Safe CR110AIS units.
The unique combination of a
CR800C Series sound level
meter and the doseBadge
personal noise dosemeter
allows almost any noise
measurement situation to be
covered.
