The Martindale SP79 is a sound level meter that features both dBA and dBC frequency weightings. This allows you to measure general sound frequencies, as well as low frequency vibrations (e.g. road works noise or aircraft flightpath noise for example). It has 3x manual ranges covering 90dB, 110dB and 130dB.
Being a Class 2 sound level meter means that the SP79 is suitable for taking on-site measurements in industrial and office environments that help you comply with the Noise at Work Legislation.
Other features of the SP79 include:
Large high contrast display (showing both digital reading and analogue bar graph)
Designed to be handheld, or mounted on a tripod
Fast and slow time weighting
Monitoring of Min / Max values
Detailed recording and analysis using the AC and DC outputs

Optional Accessories:
SPC70 (Class 2 sound level calibrator) can be used to verify accuracy before and after taking reading, as in accordance with international standards. It is easy to use and provides a 1kHz reference at 94dB and 114dB.
