Monarch 325 mini-size IEC 651 Type II Sound Level Meter

Monarch Sound Level Meters are ideal for making noise measurements in the workplace. While Noise is mainly a problem in manufacturing industries, the assessment of personal noise exposure at work must be carried out in all companies to be sure that harmful noise levels are not being exceeded. National regulations exist in almost all industrialized countries which give actual noise limits on the amount of noise allowed in the workplace. With simple operation and powerful features, the 300 Series provides an affordable method to ensure workplace safety. All the 300 Series meet the IEC 651 Type 2 standards.
