- Type Approved sound level meters to international standards IEC 61672-1:2002 and IEC 61672-2:2003 from the PTB
- Data Logging sound pressure level meters with up to 32GB of memory (enough for 1 month of noise and audio measurements)
- Integrating averaging sound pressure level meters for occupational noise & workplace noise exposure measurements
- Decibel Level Meters with a dynamic measurement range (frequency range) from 20dB(A) - 140dB(A), C-peak 143dB(C)
- Octave Band noise meters for octave band analysis and the selection of hearing PPE & Noise Control
- High-performance Decibel Meters with real-time 1:1 and 1:3 Octave Bands and Audio Recording for Environmental Noise
- Time weighting (fast, slow and impulse) and frequency weighting (A, C and Z weightings)
- Noise Frequency Real-time Analyser for detailed acoustic analysis
- A simple noise meter for basic noise testing applications.
Noise measurement kits
All of the sound meters and noise level meters in Pulsar Instruments range can be supplied as a complete noise measurement kit containing db meter, acoustic calibrator, windshield, and other essential accessories. They come with valid calibration certificates and a warranty. The Pulsar Nova range can also be used with an all-weather outdoor measurement kit that provides protection for the meter and its microphone from the elements and dust, allowing sound intensity measurements to be made over long periods in a variety of environments.
Of course, if you do have any potential questions about a sound level meter from the collection above then please let us know and the Pulsar customer services team will be more than happy to assist you further. Simply get in touch via our contact page or give us a ring and we will be happy to advise you further on any of the sound level meters you see featured.
Frequently Asked Questions
A Class 1 Sound Level Meter is a high-precision meter useful for sound level measurements for occupational noise, environmental noise and laboratory applications, although you can use it for most other acoustic measurement applications such as industrial and construction noise assessments. The tolerance in each frequency is much tighter on Class 1 than on a Class 2 meter. Most British Standards call for a Class 1, but occupational noise measurements only require Class 2.
A Class 2 instrument is still highly accurate and is perfect for occupational noise and industrial hygiene applications. For most Health and Safety applications, for example, Noise Risk Assessments, a Class 2 sound level meter is all that is required.
Yes. There are different types of calibration. You need to field calibrate your meter before and after every set of measurements with an acoustic calibrator. You need to have a periodic calibrator (factory calibration) at least every two years, however, Pulsar recommends you return your instrument annually to us for recalibration and in return, we will extend your product warranty up to 7 years. All instruments leave Pulsar Instruments professionally calibrated and are supplied with a valid calibration certificate to international standards. Pulsar can also supply your sound level meters as UKAS calibrated which is the highest level of calibration you can receive (extra charges apply for this).
Yes. We advise you use a windshield to protect the microphone from dust and environmental conditions. Our noise meters are supplied with windshields as standard. If you lose it or it gets damaged you can purchase a replacement.
Our meters can be used for a range of applications:
- Noise at work
- Occupational and industrial hygiene (to guard against hearing loss risk)
- Environmental noise measurement
- Boundary noise measurement
- Machinery noise testing
- Vehicle noise testing
- Entertainment noise measurement
A decibel db meter fitted with Octave Band Filters can split the audible spectrum into smaller bands that identify the frequency content of the sound. If you are taking environmental noise measurements we recommend you buy a meter with at least 1:1 octave band filters. If you are measuring occupational noise they are not necessary, however, some people like to use them to identify more accurately the level of hearing protection to prescribe. With the Pulsar Nova range of instruments, you can buy a meter with 1:1 octave band filters (Models 45 and 46 have it as standard), or you can choose to upgrade to this option at a later date. If you have this option, the Pulsar AnalyzerPlus software will supply a range of options of hearing PPE based on the octave frequency content of the noise you measure.
