Castle Group are acknowledged experts in noise and vibration measurement with over 30 years experience. When you buy from Castle you buy with confidence.

Pocket Power
A feature packed instrument that is fully compliant with IEC 61672-1:2002 Class 1, IEC 60651:
1979 Type 1, IEC 60804: 2001 Type 1 and IEC61252: 1993. This meter gives simultaneous Leq (rms. average) personal exposure (Lex/LEP’d) and peak measurement for assessments to the Noise at Work Regulations 1989. It has a high specification, Class 1 measurement microphone and is cased in tough, crack resistant ABS plastic.

Feature-Packed
Designed for Industrial Safety Officers and Safety Managers for compliance with the Health and Safety at Work Act; Noise at Work regulation 1989. The Castle GA113 provide all the necessary information you need for completing Noise at Work risk assessments.

• Integrated equivalent level (Leq) measurement
• Personal Sound Exposure Level (Lex) (was Lep'd)
• Optional dosemeter plug-in microphone
• Sound Pressure (Lp) to 0.1 dB resolution
• 'A' and 'C' frequency weighting (toggle)
• 'Slow' and 'Fast' Time weighting (toggle)
• Simultaneous measurement of Lp, Lmax, and Pmax
