Description

Digital sound level meter with two filter curves, built-in data logger and RS-232 interfaces. The A-filter corresponds to the human ear´s frequency sensitivity. The C-filter is linear and is ideal for inspecting machines. Decibel meter has three overlapping measuring ranges and automatic/manual scale selection according to your selection. ''Fast'' sound absorption is then used when you wish to see the variations in the sound level in the same way as the ear perceives them. The ''slow'' mode gives a stable measurement result of sound that varies or pulses. The instrument is calibrated in the frequency range 31.5 Hz for 8000 Hz and automatically registers the max and min sound levels. The peak hold function locks the highest value on the character display. Output signal ''output'' ACV/DCV. Decibel meter has built data loggers, which can store your measurement values. You can then transfer the logged measurement values to a PC for further analysis. With an optional accessory, EM-900P can also measure temperature, humidity and light.

SL-4112 complies with the requirements set out in IEC 61672 type 2 and is CE approved.

Supplied with certificate from Lutron, Norwegian, Swedish and English manual. Batteries ordered separately.
