Meter check
July 1st 2008 Two new products from Pulsar
Instruments are designed to lead
to a significant improvement to
noise measurements; the company
has just obtained full and formal
EU approval for its new acoustic
calibrators – models 105 and 106.
Acoustic calibrators set and
check the sensitivity of a sound
level meter to ensure that it reads
correctly. Pulsar says just a handful
of companies world-wide offer
Approved sound level meters, but
that even with units from these
manufacturers, all regulations insist
that the meter is calibrated before
and after every formal use.
The new Pulsar models with
sophisticated sensors meet the two
classes of the calibrator standard
IEC 60942: 2003, model 105 at
Class 1 precision level, normally for
lab use, and model 106 for use in
the field for health and safety
measurements. More articles from Pulsar Instruments Plc: |
