It has a digital output interface, which can download measurement data to a connected computer and print measurement results. It has 8 G memory and clock settings for easy storage and viewing of measurement data. The HY106 series personal acoustic exposure meters use electret microphones with a nominal diameter of 6.35mm, and are equipped with a 0.8m extension cable. The cable is equipped with a clamp so that the measurement microphone can be worn on the shoulder or helmet of the person being tested. The structure of the instrument is compact and sturdy. The instrument is equipped with a belt clip. The instrument can be worn on the waist of the person being tested, or it can be placed directly in a bag or pocket, which is particularly convenient for on-site use and carrying. The power supply of the instrument is powered by two 1.5VLR6 batteries, which can work continuously for 24 hours and it is convenient to replace the batteries.
