Discription :

Digital multi-function Sound Level Meter designed to measure sound pressure level and are commonly used in noise pollution studies for the quantification of almost any noise, but especially for industrial and environmental. The device meets the measurement requirements of Safety Engineers, Health, Industrial Safety Offices and Sound Quality control in various environment. It features Bar-graph Indicating & Max Value Holding, built-in condenser mic and digital display. It accurately measures the sound level of just about anything from sound of level of environment to mechanic, vehicle, ship, loudness of computer fans and other noise with ±1.5 dB accuracy. It has the following advantages: 30~130dB range, with A/C weighting, fast/slow response, equipped with Max mode that captures and hold the maximum noise level, provides a windscreen for filter-out unwanted signals and a 9V battery with no extra charge. In almost all countries, the use of A-frequency-weighting is mandated to be used for the protection of workers against noise-induced deafness and the only weighting mandated by the international standard, the frequency weightings "C" being optional fitments.


Features :

Has CE marking, conforms with the essential health and safety requirements set out by the European Directives
Durable and built to last long and approved by strict quality and safety standards
Completely conforms to the IEC651 TYPE 2 and ANSI S1.4 TYPE 2 set standards
Wide measurement range of 30-130dB and Instantaneous sound measure function
With two equivalent weighted sound pressure levels, A and C
With fast and slow dynamic characteristic modes
AC and DC signed output for frequency analyzer level recorder, FFT analyzer, graphic recorder etc.
Equipped with windscreen that filters the undesired or unwanted signal
With Bar-graph Indicating & Max Value Holding with large LCD screen and 4-digit LCD display readings
With Tripod mounting provision on the back of the unit for field use
With FREE protective carrying case with contoured hardened foam inside fits the instrument securely. The device is sandwiched between hardened foam when closed to achieve optimum shock absorption
