PULSAR NOVA MODEL 45 – Environmental Noise Meter

The PULSAR NOVA MODEL 45 is a premium Class 1 environmental noise meter, engineered for precision, durability, and regulatory compliance. As the flagship environmental sound level meter in the Pulsar Nova range, it delivers laboratory-grade accuracy in a rugged, handheld design suitable for both short-term and long-term acoustic monitoring.

Fully compliant with IEC 61672-1:2002, the Model 45 is designed to meet the strictest UK and EU regulations for occupational, industrial, construction, and environmental noise assessments. It combines advanced acoustic measurement technology with user-friendly functionality, making it a dependable choice for professionals who require reliable, field-ready performance.

How It Works

The PULSAR NOVA MODEL 45 uses real-time 1:1 octave band filters to measure all frequency bands simultaneously, providing an accurate picture of sound energy distribution across the spectrum. This enables both precise hearing protection selection and detailed environmental noise analysis.

Its integrating and averaging capabilities record essential metrics such as Leq, Ln values, TWA/dose, and maximum/minimum sound levels, while the included AnalyzerPlus software allows instant data transfer and report generation. The built-in audio recording and automatic timers enable extended, unattended environmental monitoring sessions, ensuring complete and verifiable acoustic data collection.

The removable pre-amplifier allows the Model 45 to be used with microphone extension cables, and with the addition of an Outdoor Kit, it transforms into a fully weatherproof environmental sound monitoring system for long-term field measurements.
