CR261S Vehicle Noise Sound Level Meter
The CR261S is a Class
1 Sound Level Meter
designed for the measurement of vehicle exhaust
noise in line with the international standard ISO 5130. It
can be used as a simple hand-held meter or, more usefully,
fitted on a small tripod by the exhaust and operated using
the Remote Control.
- Noise Testing to ISO 5130 - Measurement of Noise
Emitted by Stationary Road Vehicles - Survey Method
- Static Noise Testing of cars, motorcycles, trucks and
mopeds
- Class 1 to IEC 61672 and ANSI S1.4
- Remote Control for operation while supervising engine
speed
- Automatic calibration
- Quick and easy to use, ensuring the reliable measurement
of the correct parameter

In line with the ISO 5130 standard, the CR261S is a Class 1 or
Type 1 meter to IEC 61672, IEC 60804 and ANSI S1.4. The Class 1
meters are more accurate than Class 2 and the ISO standard demands
this level of accuracy. As a result of it being specifically designed
for the noise testing of motor vehicles, it is very quick and easy
to use, with only the functions needed for this type of application.
The meter's case, which is designed for acoustic performance, is
of a robust alloy, making it ideal for use in workshops, garages
and by the road side.
Vehicle Noise Measurements
When used as a simple hand-held meter, the CR261S measures the
Fast Sound Level, LAF. When used with the Remote Control,
which plugs into the bottom of the meter, it makes three consecutive
measurements, as required by the standards. The meter shows the
three Maximum Sound Levels, LAFmax, that were measured. The use
of the remote control allows the user to operate or monitor the
operation of the vehicle's throttle whilst still controlling the
start of measurements. It is possible for a single person to make
the measurements.

measurement standards, please visit the Using
It page.

Independent Approval
The CR261S Sound Level Meter has received independent PTB
approval to DIN EN 61672. The PTB approval number is PTB-1.72-4025043.
Such approval is only granted to equipment that meets the
very strict international sound level meter standards. This
approval is assurance that the sound level meter performs
as claimed. |
