The Castle Sonus GA116L is a pocket-sized, Class 1 data-logging sound level meter offering a cost-effective solution for Noise at Work and environmental noise assessments. Fully compliant with IEC 61672-1:2002 and meeting BS 4142:2014 requirements, the GA116L integrates timestamped Leq measurements, multiple frequency weightings (A, C, Z), and RMS/peak detection into a rugged handheld instrument. It includes the free dBDataLite noise-analysis software and can be configured as a personal sound exposure dosemeter when paired with an external pre-amplifier.

Features

  • Standards compliance: IEC 61672-1:2002 Class 1; IEC 61252:1993 personal sound exposure meter; BS 4142:2014 industrial/commercial noise rating
  • Data logging: up to 2 100 intervals with date/time stamps for Leq, Lmax, Pmax
  • Frequency weightings: A, C, Z; Time weightings: Slow, Fast, Impulse
  • Exchange rate: 3 dB, 4 dB, 5 dB; Criterion level: 75 dB, 80 dB, 85 dB, 90 dB; Threshold: –5 dB, –10 dB, or off
  • Selectable ranges (display/linear/peak): 30–100/30–100/40–103 dB; 50–120/50–120/60–123 dB; 70–140/70–140/80–143 dB
  • Detector: RMS and Peak
  • Display: custom alphanumeric LCD, digits 7 × 5 mm
  • Microphone: ACO 7146A pre-polarised ½″ condenser, 25 mV/Pa; calibration 91.0–120.0 dB @ 1 kHz
  • Power: 1 × 9 V PP3 battery, ~12 h continuous use
  • Environmental: –10 °C to +50 °C operating; humidity effect < 0.5 dB (25–90 % RH); vibration-insensitive

Common Applications

  • Workplace noise monitoring and compliance (Noise at Work)
  • Environmental impact and community noise studies
  • Industrial/commercial noise assessment under BS 4142
  • Personal noise-exposure monitoring with optional pre-amplifier
