产品概述
The HY114A sound level meter is a handheld instrument, and its 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 X sound level meters, which is suitable for on-site measurement of off-line noise detection stations of complete vehicles and noise, ambient noise, traffic noise, workplace noise, etc. of mechanical and electrical products.
The sound level meter preamplifier is set to be removable, and the microphone and the sound level meter body can be conveniently connected through an extension cable, keeping the measurer away from the noise source. The instrument has a digital output interface, which can be used as a noise data collector, analyzed and processed through the PC program, and the measurement results can also be printed on-site.
Core Strengths
■The performance meets the requirements of GB/T 3785 and IEC 61672 level 2, and the measurement results are in compliance with the standard. ■The preamplifier is removable, the microphone and the main body can be connected by an extension cable, and the measurer is reliably away from the noise source, making the measurement safer. ■The extension cable comes standard with 3m and can be customized by the user, with a maximum length of 50m, which is suitable for long-distance measurement of vehicle inspection. ■A sound level 30-130dB, C sound level 40-130dB, divided into three levels of low/medium/high range, hand switching, wide range coverage. | ■128 × 64 dot matrix liquid crystal display, resolution 0.1dB, with overload, under-range, low battery voltage alarm signs. ■It has an RS232 serial communication port, outputs ASCII codes, and can be used as a noise data collector to access PC software for analysis and processing. ■DC logarithmic and AC linear analog outputs are provided to facilitate access to external recording and analysis equipment. ■The 4-section No. 5 battery can work continuously for 16h, handheld and portable, suitable for station mobile operation. |
