The GA116B sound pressure level meter brings Class 1 performance to applications such as Fire Alarm Testing and initial spot-check assessments to the Noise at Work Regulations (2005). Engineers, Industrial Safety Officers or anybody in need of competent sound measurements will find this an ideal instrument. It is a Class 1 Sound Level Meter that is fully compliant with IEC 61672-1:2013 giving that extra security in measurements, especially in legal matters. It has the ability to measure Sound Pressure (Lp), maximum Lp hold (Lmax) and Peak (Cpeak) simultaneously. When recording, the user can cycle through all measured parameters with the push of a button.

Supplied with a fully calibrated microphone the GA116B is ready for use straight from the box with full confidence in accuracy
