Pulsar Model 46 Nova Sound Level Meter Repair
The Pulsar Model 46 Nova Sound Level Meter is a sound level meter – the microphone is the instrument. Everything downstream is interpretation, and a microphone that has drifted or been damaged produces measurements that are wrong in a way no amount of processing recovers.
June Company repairs and calibrates the Pulsar Model 46 Nova Sound Level Meter for occupational hygienists, environmental consultants, acoustic engineers, and safety departments. Every instrument is repaired at component level and verified against reference standards before it ships back, with the measured results documented.
