The Laser 6605 is a high quality Sound Level Meter used for measurement of mechanical and
environmental noise. It is a Class 2 Sound Level Meter designed to meet the requirements
of IEC 61672-1. Typically, Class 2 Sound Level Meters are suitable for occupational
noise measurements such as the UK Controls of Noise at Work Regulations or the OSHA
Occupational Noise standards.
Thus it is ideal for:
• Occupational and industrial hygiene noise evaluations.
• Noise at Work surveys and Noise Exposure calculations.
• Noise Ordinance Enforcement.
• Machinery noise tests.
• General noise measurements.
When the low battery symbol appears on the LCD display, replace the 9V battery (refer to

dampness or condensation.
• If the instrument is not to be used for a long period, remove the battery to avoid harmful leakage.
• Keep microphone area dry and avoid severe vibration.
• Protect the instrument from electromagnetic fields and static electricity.

Precautions
•
Always wear ear defenders
when testing sound levels in a new situation. Damage to the human
ear can begin at 85dB and above.
Do not assume the sound level is safe until you have
actually measured it
.
• When testing sound levels near working machinery, be aware and take particular care around
rotational parts such as belts, pulleys and fans, etc.
• Do not let untrained persons use the instrument.
