Need a handheld device to measure noise levels in your workplace? You can use this RS PRO NDM1355 sound level meter to get accurate readings of noise levels and assess noise exposure.
This sound level meter returns measurements in units called A-weighted decibels (dBA), which express the relative loudness of sounds in air as perceived by the human ear. It allows you to take readings of the percentage of the noise dose, exposure time and sound level. The device is small in size so you can carry it with you easily. It also features data storage of up to five events, so you can save your readings.
The meter can be connected to your PC using the RS232 cable included in the kit. It's supplied with the software on the CD ROM, so you can work with your measurements. The kit also includes a case, a calibration screwdriver and four AAA batteries, so the meter is ready to use.
