DEDRA MC0956 geluidsniveaumeter – 30-130 dBA digitale decibelmeter met A/C-weging, achtergrondverlicht lcd, Data Hold, Max/Min, IEC 651 Type 2

Excessive noise in workshops, construction sites, or public venues isn’t just an annoyance—it can lead to hearing damage, regulatory fines, and compromised work quality. Without a reliable way to measure sound pressure levels, you’re left guessing. The DEDRA MC0956 Sound Level Meter gives you precise, repeatable readings from 30 to 130 dBA, so you can assess noise exposure, verify compliance, and protect your hearing with confidence.

Who is it for

This meter is built for occupational health and safety officers, HVAC technicians, event organizers, audio engineers, and anyone who needs to quantify environmental noise. It’s equally at home in a factory, a recording studio, a school auditorium, or a residential neighborhood. If your work involves noise assessment or you simply want to monitor the sound around you, the MC0956 delivers professional-grade measurements in a compact, handheld form.

Main features

• Wide measurement range: 30–130 dBA (A-weighting) and 35–130 dBC (C-weighting) covers everything from quiet offices to loud machinery.
• High accuracy: ±1.5 dB at 1 kHz, meeting IEC 651 Type 2 and ANSI S1.4 Type 2 standards for reliable field measurements.
• Dual frequency weighting: A-weighting mimics human hearing for general noise surveys; C-weighting captures low-frequency peaks for industrial and entertainment environments.
• Fast and slow time weighting: FAST (125 ms) for transient sounds, SLOW (1 s) for averaging fluctuating noise.
• Backlit LCD display: Clear digital readout with 0.1 dB resolution, easily visible in dimly lit areas.
• Data hold and max/min functions: Freeze the current reading or review the highest and lowest values captured during a session.
• Auto power off: After approximately 15 minutes of inactivity, the meter shuts down to conserve battery life.
• Electret condenser microphone: 1/2-inch capsule provides stable sensitivity and broad frequency response from 31.5 Hz to 8 kHz.

Tips

For consistent readings, hold the meter at arm’s length and point the microphone toward the noise source. Use A-weighting for general environmental assessments and C-weighting when measuring low-frequency noise from engines or music. Calibrate the meter periodically with a sound level calibrator to maintain accuracy. Replace the 9V battery when the low-battery indicator appears to avoid measurement drift.
