Feature

●(Applications) This noise meter has an instant sound measurement function. Measurement range is 30-130dBA 35-135dBC. There are two equal weighted sound pressure levels, A and C. This volume meter is used to measure the volume of your work or life acoustic equipment such as factories, workshops, schools, residentials, office areas, traffic roads, audio, etc
●【HD LCD Screen with Backlight】 In order to achieve a clear view, we use a HD LCD screen with backlight. Clear reading, easy to use at night
●【Split Probe for Longer Sensing Lines】The split probe extends the sensing line so that it can be measured away from high temperature sources. Adopts K-type thermocouple for unique contact temperature measurement
●【Volume Measurement】This noise meter is suitable for the output with AC and DC code such as frequency analyzer level recorders, FFT analyzers, graphic recorders, etc. Microphone: 1/2" Electret Condenser Microphone Max:Max Hold Power Supply: 9V battery (not included) or DC9V 100mA Self-calibration time: 10 seconds (turns on every time) Operating Temperature: 0℃~40℃ Operating Humidity: 10%-80%RH Storage Temperature: -10℃~60℃ Storage Humidity: 10% to 70% RH Weight: about 664g Size: about 224 * 66 * 33mm

General noise range

0-20dB Very quiet and hardly heard 20-40dB Quiet 40-60dB Normally regular indoor conversation 60-70dB High noise and 70-90dB which can cause nerve damage 90-100dB increase noise and hearing loss 100-120dB inability temporarily ear Unheard 12 Over 0 dB Completely inaudible

Noise Harmful

Long-term exposure to noise is a serious impact on the human nervous system, cardiovascular system, digestive system, and endocrine system. Increases the occurrence of hyperpressure affects pregnancy women and decreases IQs in newborns affected by work and study
