Sound Level Meters for Environmental & Occupational Noise
Contents
1. The optimus sound level meters have been designed with ease of use as the most important feature which lets you get on with measuring and controlling the noise The instruments use the very latest in digital technology and industrial design techniques to make everything as clear and simple as possible We ve used a high resolution colour OLED screen which can be seen in any conditions and the low light The case is robust and covered with a tactile finish so it can be Used even if you re wearing gloves The measurement data is displayed in a clear and simple format along with a real time noise chart so that you can see how the noise varies with time All of the Functions of the instrument are measured simultaneously and with a wide 120dB measurement span you don t need to worry about choosing the right range An optimus can measure up to 140dB A and 143dB C Peak in this Single range Just switch on calibrate and you are keypad will illuminate automatically in The ideal solution for environmental amp occupational noise The optimus green sound level meters are the ideal sound instruments for environmental amp occupational noise as well as for basic noise surveys and will give you all of the information you need right at your finger tips Each and every measurement contains all of the available Functions so there s no risk of selecting the wrong parameter or function Environmental Noise M2. i i5 Fa fame x 3 B a Ces Sart i ALAN Ny vuh i vial f whl i au I yen it LAN l th had w m x anament Dimman AAMAR noisetools A t we _ j TEF SOROO RROD EEE D PEE ESS Waadael sit ti wi er J Complete measurement kits are available for the optimus instruments which contain the instrument an acoustic calibrator windshield cables batteries and accessories The measurement kits contain all of the accessories needed to carry out a noise survey Specifications PaCcirrus Applicable Standards IEC 61672 1 2002 Class 1 or Class 2 Group X IEC 60651 2001 Type 1 or Type 2 IEC 60804 2000 Type 1 or Type 2 IEC 61252 1993 Personal Sound Exposure Meters ANSI 1 4 1983 R2006 ANSI S1 43 1997 R2007 ANSI 1 25 1991 1 1 amp 1 3 Octave Band Filters to IEC 61260 amp ANSI 1 11 2004 Microphone Class 1 Instruments MK 224 pre polarized Class 2 Instruments MK 216 pre polarized Microphone Preamplifier MV 200E Removable Preamplifier Total Measurement Range 20dB to 140dB RMS Single Range Noise Floor lt 18dB A Class 1 lt 21dB A Class 2 Frequency Weightings RMS amp Peak A C amp Z Measured Simultaneously 1 1 Octave Bands 31 5Hz to 16kHz 1 3 Octave Bands 6 5Hz to 20kHz Bands from 12 5Hz displayed 6 3Hz 8Hz amp 10Hz stored amp downloaded B Version Time Weightings Fast Slow amp Impulse Measured Si
3. simple to use The initial summary screen shows you the most commonly used information and through simple icons gives you access to the detailed measurement data You can simply print the summary screen to get a quick measurement report For advanced users each and every function measured by the instrument is available for review and analysis and the data can be exported for Further use Voicelag recordings can be played back for reference and are automatically stored with the measurement data Audio recordings can be played back to identify the noise source and analysis performed on the recordings Where Octave Band data is available this information can be used by the program to calculate the level of protection from a range of hearing defenders and ear plugs Helping you keep you data organised Over time you may find that you have a large number of measurements information and notes To help you keep your noise measurement data organised and easy to find NoiseTools allows each measurement to be allocated to people places and projects Instrument Range amp Measurement Kits The optimus green sound level meters can be used for a wide range of occupational and environmental noise applications and you can choose From 2 simple options to get the instrument that meets your needs Choose from Class 1 or Class 2 performance and the choose either Audio Recording or Audio Recording with real time 1 3 Octave Ba
