Castle Sonus Class 1 Integrating Sound Level Meter 35 dB to 140 dB 20 kHz Max GA116i

Castle GA116i Sonus Class 1 Integrating Sound Level Meter is a highly accurate acoustic instrument designed for industrial safety professionals, engineers, and safety managers requiring compliance with noise control regulations. It works within a measurement range of 35 dB to 140 dB and can capture sounds up to 20 kHz frequency, delivering precise sound pressure and dose measurements important for workplace noise exposure assessments.

This sound level meter supports simultaneous readings of several acoustic parameters such as Lp (sound pressure level), Leq (equivalent continuous sound level), Lmax (maximum sound level), Cpeak (C-weighted peak level), Lep,d (personal sound exposure), LAE (event sound exposure level), noise dose percentage, and dose per hour percentage. It also includes adjustable frequency weighting (A and C) and time constants (fast and slow) to suit diverse measurement conditions.

The GA116i features a bright LCD screen and USB connectivity, facilitating monitoring and data transfer. Its robust ABS plastic enclosure offers protection against impacts and industrial wear, making it suitable for harsh environments. Operating temperature ranges from -10°C to 50°C ensure reliability in various climatic conditions. Battery life extends up to 12 hours powered by a PP3 battery, supporting extended field use without interruption.

This meter adheres strictly to IEC 61672-1:2002 Class 1 and related international standards, guaranteeing regulatory compliance. It is particularly suited to noise exposure monitoring under the Control of Noise at Work Regulations 2005, providing both LAeq and LCPeak measurements for comprehensive workplace noise assessment including hearing protection evaluations.

Castle GA116i supports industrial, environmental, construction, and manufacturing applications where precise noise level monitoring is critical. The sound level meter is an essential tool for health and safety audits, regulatory submissions, and occupational noise control programs across multiple sectors.

Complies with IEC 61672-1:2002 Class 1 accuracy standard. Measures Lp, Leq, Lmax, Cpeak, Lep,d and LAE with frequency weighting A and C. Fast and slow time averaging for versatile measurement. LCD display with USB interface for data management.

Robust ABS plastic housing perfect for industrial use. Operating temperature from -10°C to 50°C for field durability. Long battery life of up to 12 hours with PP3 battery. Designed for professional noise exposure risk assessments and compliance.
