Instruments for Airborne Sound, Noise

The ear is besides the eye the mostly used sense organ of humans.

Via sound events in our environment - talks, music bird's twitter or machine noise etc we participate in our environment by means of our ears.

Ear is a pretious sense organ, which must be protected. Especially in professional everyday life machine noise arises in a way we feel troublesome. Everybody knows that noises and sound events, which are too loud can damage the ears persistently, in the long run. By means of the sound level meters described below, sounds and noise or pure tones can be measured and evaluated.

Be it at the working place, in machine shops, offices, discotheques or in environmental range, control of noise levels is important and mostly even mandatory.

Peak Tech 3695, 5 in 1 Digital Multitester

Peak Tech 3695, 5 in 1 Digital Multitester

Professional multitester with large LCD, showing 2 lines of readings and supplied with backlight for easy reading. This multitester combines the functions of sound-, lux-, humidity-, temperature measurements and with a digital multimeter, which is provided with light and sound alarm to prevent misconnections of test leads. It provides additional protection against damages caused by improper operation.

the sound level function is applicable to measure in factories, schools, offices, airports, and for checking the acoustics of studios, auditoriums and hi-fi installations

the luminance function is applicable for measuring field luminance with full cosine correction for angular incidence of light

the humidity and temperature functions are suitable for measuring ambient humidity and temperature, as well as temperature of objects

the digital multimeter can perform measurements of AC/DC voltage and current, resistance, frequency, duty capacitance, as well as continuity and diode test

overload protection and low battery indication

resetable fuse (400 mA)

auto power off function

hold function

relative measurement function
