A CES 803 Digital Sound Level Meter accurately measures noise and sound levels in various environments, helping monitor workplace safety, environmental noise, and product acoustics. Portable and easy to use, it provides precise readings for compliance, analysis, and sound quality assessment.
Caltech India is the leading manufacturer and supplier of CES 803 Digital Sound Level Meter. A sound level meter (also called sound pressure level meter) is used for acoustic measurements. It is commonly a hand-held instrument with a microphone. It is an instrument for measuring environmental noise, which can be used in the fields of machine manufacturing, equipment maintenance, architectural design, transportation, environmental protection and health care. Sound level meter is also known as noise dosimeter.
CES 803 Decibel Meter (dB Meter) resolution is 0.1dB, accuracy is ±1.5dB. The instrument supports A and C frequency meter rights. A weight attenuates the low frequency components of the original noise signal of the environment more, simulates the auditory characteristics of the human ear, evaluates the noise size from the hearing, so it is the most widely used, and the weight has less modification to the original noise signal of the environment. Can truly reflect the noise of the environment.
CES 803 Noise Meter support SLOW and FAST time weights. The time constant of SLOW time weight is 1 second, which is used to measure steady state noise, and the time constant of FAST time weight is 125 milliseconds, which is used to measure fast changing unstable noise.
CES 803 Acoustic Level Meter also provides a 3.5mm audio interface that outputs both DC and AC signals. DC interface outputs DC voltage signal, the voltage is proportional to the noise value (10mV/dB), which can be used for the secondary calibration of data or the expansion of display equipment, and the AC interface outputs AC voltage signal, which can be used for spectrum analysis of environmental noise.
