AZ8925數(shù)字噪音計(jì)/分貝計(jì)是一款經(jīng)濟(jì)實(shí)用的便攜式聲級測量儀器，適用于多種場景。它采用口袋型設(shè)計(jì)，便于攜帶和操作，重量僅約190克。該設(shè)備具備A/C兩種頻率加權(quán)特性，能夠測量A環(huán)境噪音（40～130dB）和C機(jī)械噪音（45～130dB）。它還提供4檔手動測量檔位，分別為40-70dB、60-90dB、80-110dB和100-130dB。

其顯示功能強(qiáng)大，配備3 1/2位液晶及條碼顯示，屏幕尺寸為37x40mm，可同時(shí)以數(shù)字及類比顯示音量。此外，該設(shè)備支持FAST（快）/SLOW（慢）兩種響應(yīng)時(shí)間選擇，能夠記錄最大/最小值，并具備鎖定讀值功能。它還內(nèi)置10mm電容式麥克風(fēng)，確保測量的準(zhǔn)確性。

在操作方面，AZ8925具備自動及手動關(guān)機(jī)功能，可節(jié)省電力。其工作溫度范圍為0℃至50℃，相對濕度小于90%，儲存溫度范圍為-10℃至60℃，相對濕度小于70%。該設(shè)備使用9V電池供電，也可選擇4×1.5V AAA電池。

The AZ8925 Digital Noise Meter/Decibel Meter is an economical and portable sound level measuring instrument suitable for various scenarios. It features a pocket-sized design for easy carrying and operation, with a weight of only about 190 grams. This device has A/C frequency weighting characteristics and can measure A-weighted environmental noise (40～130dB) and C-weighted mechanical noise (45～130dB). It also offers four manual measurement ranges: 40-70dB, 60-90dB, 80-110dB, and 100-130dB.

The display functions of the AZ8925 are robust, with a 3 1/2-digit LCD and bar graph display, measuring 37x40mm, capable of showing sound levels both digitally and analogically. Additionally, the device supports FAST (quick) and SLOW (slow) response time options, can record maximum and minimum values, and has a readout lock function. It also features a built-in 10mm condenser microphone to ensure accurate measurements.

In terms of operation, the AZ8925 has both automatic and manual shutdown functions to save power. It operates within a temperature range of 0℃ to 50℃ and a relative humidity of less than 90%, and can be stored in temperatures ranging from -10℃ to 60℃ with a relative humidity of less than 70%. The device is powered by a 9V battery, or alternatively, four 1.5V AAA batteries.
