Musktool-JY104H Class 2,Type 2 High Sound Level 150dB Sound Level Meter,SONÔMETRO,Decibelímetro Digital
INTRODUCTION
| The Musktool-JY104H sound level meter is a hand-held instrument whose performance meets the requirements of the national standard GB/T 3785－2010 and the international standard IEC 61672:2013 "Sound Level Meter" for Class 2 Class X sound level meters. It is a High sound level sound level meter, optimize the circuit on the HY104 sound level meter, and use a high sound intensity microphone to extend the upper limit of the sound level meter measurement range to 150 dB, which is suitable for the measurement of high sound level noise. |
TECHNICAL SPECIFICATION
| Musktool-JY104H(High Sound Level 150dB) | |
| Accuracy | Class 2/Type 2 |
Measured evaluation data: | Measured evaluation quantity: LP (time-weighted sound level), Lmax (maximum time-weighted sound level) |
| Microphone | Microphone: HY205 type 2 engineering measurement microphone, nominal diameter 12.7 mm, free field frequency response. The nominal sound pressure sensitivity is 8mV/Pa (the nominal sound pressure sensitivity level is -42dB, and the reference value is 1 V). |
| Frequency range: | 20 Hz～16 kHz. |
| Frequency weighting: | A weighting, C weighting. |
| Time weighting: | F (fast response). |
Measuring Range | A sound level: 50 dB～150 dB; C sound level: 60 dB～150 dB, divided in o three levels: Low gear: 50 dB～110 dB; Middle gear: 70 dB～130 dB; High gear: 90 dB～150 dB, hand selected. |
| Display | 128×64 dot matrix liquid crystal display (LCD), resolution 0.1dB, with signs of overload, under-range, low battery voltage, etc. |
| Analog Output | Analog output: The output jack is a 3.5 mm dual-channel headphone jack, and the minimum load impedance is 10 kΩ. ——DC logarithmic voltage: The output voltage is related to the logarithm of the measured sound pressure, and the output voltage is related to the level range. The unit sound pressure output voltage is 30 mV/dB. The range of each level is +300 mV～-1500 mV, and the upper and lower boundaries of each level range are respectively -1500 mV and +300 mV. ——AC linear voltage: The output voltage is linearly related to the measured sound pressure, and the output voltage corresponding to the upper boundary of the level range is 0.5 V. |
| Power Supply | 2 6F22 type 9 V laminated batteries, which can work continuously for 10 hours under reference environmental conditions. |
