Casella 62x & 63x Series Sound Level Meters
Class 1 vs Class 2 Sound Level Meters
The difference between Class 1 and Class 2 sound level meters lies primarily in their precision, tolerance, and intended use cases, as defined by the IEC 61672-1 standard:
Class 1 vs Class 2 Sound Level Meters
| Class 1 Sound Level Meters | Class 2 Sound Level Meters |
|---|---|
| Accuracy: Higher precision with tighter tolerances | Accuracy: Lower precision compared to Class 1 |
| Frequency Range: Typically 10 Hz to 20 kHz | Frequency Range: Typically 20 Hz to 8 kHz |
| Tolerance: ±1.0 dB or better | Tolerance: ±2.0 dB |
| Use Cases: Environmental noise assessments, legal compliance, industrial studies, laboratory work | Use Cases: Workplace noise monitoring, machinery noise tests, general field measurements |
Casella CEL-62x Series – Workplace Noise Monitoring
The CEL-62x Series Integrating Digital Sound Level Meters are designed for occupational noise assessments to comply with EU, OSHA, and ACGIH workplace noise legislation. These meters can be used for machinery noise tests, noise at work compliance, and to assist with the selection of hearing protection.
- Measures all workplace noise parameters in compliance with legislation
- Choose Class 1 or Class 2 microphone models
- Octave Band analysis available (B models) for hearing protection selection
- High-resolution colour display with intuitive colour-coded screens (green = measuring, red = run ended)
- Graphical noise environment display for easier interpretation
- On-site calibration with CEL-120 Series Calibrator
- Six selectable setups – four pre-defined to legislative standards, two customisable
- Measures and stores ALL parameters, regardless of setup
- Date & time stamped runs – stores up to 100 measurements
- USB connection – easy review of data without proprietary software
- Single measurement range (20–140 dB) – no range switching required
- CEL-620B models: Real-time octave band analysis with dominant frequency highlighted
- Time history display of broadband noise levels
Applications
- Noise at work compliance assessments
- Machinery noise testing
- Selection of hearing protection
- Noise exposure calculation
