Sound level meter

Designed for both industrial and office on-site measurement, the SP79 is a user friendly sound level meter which features A and C frequency weighting and fast and slow time weighing.

Compact and lightweight in design, the SP79 offers ease of use and can be conveniently handheld for spot checking noise levels, or mounted on a tripod for longer term monitoring of Min/Max values.

Featuring an intuitive design to allow quick, simple and effective screen navigation, the large high contrast display also includes both digital and an analogue bar graph. Easy to operate, the robust SP79 complies with BS EN 61672-1:2003 and comes supplied with a detachable windshield and a durable carry case for long term high performance.

Also available from Martindale Electric is the SPC70 Class 2 Sound Level Calibrator.  As with any noise measurement equipment, the sound level meter must be calibrated before and after each use to check that it is measuring correctly.  The SPC70 from Martindale is suitable for periodic testing of sound meters and verifying accuracy before and after readings, in accordance with national standards.

Compatible with the SP79 and other meters with microphones up to 25mm, the SPC70 provides a 1 kHz reference at 94dB and 114dB.  The output is accurate to 0.5dB with low levels of harmonic distortion.

The Health & Safety Executive (HSE) 2005 Control of Noise at Work Regulations define the limits of noise levels to which employers can be exposed to over a working day, employers now have the responsibility to ensure noise exposure and level limits are monitored and kept to a minimum.

Covering the obviously noisy industrial premises and construction sites, the regulations also cover work places where the risk of noise may not be immediately obvious.

As noise regulations take on an even greater role in modern business, the new SP79 and SPCC70 from Martindale Electric help organisations adhere to the these regulations and stay compliant.
