Description
Pulsar Model 45 Nova Sound Level Meter Repair
The Pulsar Model 45 Nova is an integrating sound level meter — a handheld instrument that measures and logs sound pressure level and related acoustic parameters (with frequency weighting and integration) for occupational noise and environmental assessments. As a precision acoustic instrument, its faults concentrate in the microphone and preamp, the weighting/measurement electronics, the display, and the battery.
June Company repairs and calibrates the Pulsar Model 45 Nova for occupational-hygiene and environmental-noise teams.
Common Pulsar Model 45 Nova problems we fix
- A/C weighting-filter drift — the A/C frequency-weighting filters drifting out of spec, recalibrated against standards.
- Microphone / preamp faults — a damaged or drifting microphone skewing levels, repaired or replaced.
- Display faults — blank, dim, or erratic display, repaired.
- Level-measurement out of spec — measurement drift, recalibrated.
- Battery or logging faults.
FAQs
My Model 45 weighting or levels look wrong — fixable? Yes. Weighting-filter and microphone faults are repairable, then the meter is recalibrated so sound-level measurements are accurate, with a NIST-traceable certificate.
Is the microphone verified? Yes — the mic and weighting are checked against our acoustic standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
