The IEC 61672-1 specifies “three kinds of sound measuring instruments”.[1] They are the “conventional” sound level meter, the integrating-averaging sound level meter, and the integrating sound level meter. The standard sound level meter can be called an exponentially averaging sound level meter as the AC signal from the microphone is converted to DC by a root-mean-square (RMS) circuit and thus it must have a time-constant of integration; today referred to as the time-weighting. Three of these time-weightings have been internationally standardised, ‘S’ (1 s) originally called Slow, ‘F’ (125 ms originally called Fast and ‘I’ (35 ms) originally called Impulse. Their names were changed in the 1980s to be the same in any language. I-time-weighting is no longer in the body of the standard because it has little real correlation with the impulsive character of noise events.

Most machines work in environments where noise – levels are high. It is difficult to identify particular sounds / noise elements associated with rotational fluctuations within that ambient sound. If the machine is running with / without adequate lubrication , normal noise is disturbed and the ‘frictional noise’ can only be distinguished and measured by such sensitive instruments as the ZKL Sound Level Meter which are accurate upto 130dB. This meter is an invaluable aid on the shop – floor helping technicians and other users to measure sound levels , detect any flaws / problems and helping them to take corrective / remedial measures. Who would benefit The ZKL Sound LEVEL Meter is the instrument – of- choice for Safety Engineers , Health , Industrial Safety Offices and Quality Control Departments working in varied environments as IEC 651 Type – II, ANSI S1.4II.

Multiple Measurements LCD Display AC or DC outputs Battery Powered The VIB-M is a battery powered portable instrument designed to operate with a constant current type accelerometer to make vibration measurements simple and convinient Pk, RMS and p-pk are the various parameters that can be measured for acceleration, velocity and displacement. A switched low pass filter for the reduction of wide band noise is provided for Vib-M. Theere are two versions available: VIB-M and VIB-M-1.
