These meters compute average sound pressure level (LEQ/LAVG) over the run time, helping you to more accurately assess occupational and environmental noise levels. Instruments are available in Class/Type 1 and Class/Type 2 models.
Type 1 or Class 1 sound meters are used for incredibly precise noise measurements (such as in laboratories) as they are able to measure the smallest sound levels. Class 2 sound level meters are usually used in workplaces for assessing and measuring noise.
1 Οκτ 2018 · A Class 1 sound level meter is generally seen as more accurate than a Class 2 meter; and, A Class 1 sound level meter is able to measure sound over a wider frequency range than a Class 2 meter.
This portable high-accuracy sound level meter has a large easy-to-read illuminated LCD screen that displays the sound pressure level (SPL) numerically and graphically in real time. The sound level meter calculates the equivalent continuous sound level Leq (LXeq). Measuring range: 25 … 136 db (A)
The Type or Class of a sound level meter describes its accuracy as defined by the relevant international standards - Class 1 is more accurate than Class 2. The older standard IEC 60651 referred to the grade as "Type", whereas the new standard IEC 61672 refers to it as the "Class".
Features and Benefits. ANSI and IEC standards compliant. Available in Class/Type 1 Precisions or Class/Type 2 General Purpose models. Two “virtual” sound level meters running simultaneously. Concurrent A-weighted and C-weighted measurements. Programmable and level-triggered start and stop. A, C and Z (flat) frequency weighting.
Class 2 Sound Level Meter, also known as Type 2 Sound Level Meter, is a professional noise level meter designed to meet the requirements of the IEC 61672-1:2013 standard for precision and accuracy.
