Sound Level Meter
Kethvoz Digital Sound Level Meter Dual Interface Decibel Meter with 30-130 dB Measurement Range, A/C Rating and AC/DC Output, as Well as Automatic Calibration for Noise Monitoring
$0.00
- Professional Decibel MeterComplies with IEC651 TYPE2 and ANSI S1.4 TYPE2 international standards, with an accuracy of 1.5dB. Its frequency response covers 31.5Hz~8.5kHz, enabling accurate capture of sound signals from 30~130dB (featuring dBA/dBC double weighting mode). It consistently and accurately detects noise in both domestic scenarios (neighborhood/appliance decibels) and industrial/office environments (building construction noise)
- Dual Interfaces for Practical UseEquipped with AC/DC dual output interfaces: AC output (0.707V rms) can connect to frequency analyzers, FFT analyzers, etc., while DC output (10mV/dB, with an output impedance of approximately 100) is suitable for recorders to facilitate in-depth data analysis. A tripod mounting screw is located on the bottom of the body to free your hands. It automatically calibrates 10s after power-on to ensure the accuracy of each measurement
- Easy to Operate and Clear DisplayFeatures a 5-digit LCD screen (0.1dB resolution, 0.5S response) and a 50dB scale bar graph (1dB step, 50ms refresh). The backlight function ensures clear readings in dark environments. Its operating logic is simple: a knob for quick range switching (4 positions), time weighting adjustment (“FAST” for instantaneous peaks / “SLOW” for average fluctuations), and a MAX key to lock the maximum value with a single touch
- Long-lasting and Easy to Use AnywhereThe decibel meter has a palm-sized design and weighs about the same as a phone. Its durable construction makes it suitable for a wide range of environments, from 0C to 40C and 10% to 80% RH. A single 9V alkaline battery provides approximately 30 hours of use, or it can be powered by a 9V DC adapter
- Thoughtful DetailsComes with a windscreen to avoid data deviation. Removing the battery when not in use for an extended period prevents leakage that could damage the unit and extends its lifespan. It is recommended to calibrate the device once a year to maintain accuracy. The manual provides clear instructions from battery installation to function adjustment, making it easy to start monitoring immediately
