Overview
Enviro Testers Electric Noise Level Meter is a digital and multifunction sound level meter with modular design. Its performance accords with standard IEC 61672: 2002 Class 1, belongs to group X sound level meter for specifying the emission, and susceptibility to radio frequency fields. The meter has adopted advanced digital detection technology and has automatic range conversion, reliable and steady performance, wide linear operating range etc. The shell adopts ABS engineering plastic with beautiful shape, light weight and be easy to carry. The power consumption of is small. Through the RS-232 digital output interface can use computer remotely control telemetry, also can set many as a network, with computer control and measurements. It is applied widely in the measure noise produced from various machines, vehicles, boats, electro etc. Also measure environmental noises and industrial noises, e.g. labor protection, industrial hygiene. Sound level meter has many types, they are in the same structure and same working principle, only are different from microphone and software authorization.
