以下是AZ8000光電式轉(zhuǎn)速表/AZ-8000的產(chǎn)品中英文介紹：

AZ8000光電式轉(zhuǎn)速表是由臺灣衡欣公司推出的一款非接觸式轉(zhuǎn)速測量儀器。它采用光電反射原理進(jìn)行測量，通過發(fā)射紅外線并接收經(jīng)待測目標(biāo)反射的光線來獲取轉(zhuǎn)速信息。該轉(zhuǎn)速表具有免接觸式測量的特點，可避免因接觸測量而對被測物體造成的影響。其操作簡單便捷，即使是初次使用的用戶也能快速上手。它還具備自動換擋功能，能夠根據(jù)不同的測量需求自動切換量程。此外，該轉(zhuǎn)速表在20分鐘內(nèi)未操作時會自動關(guān)機(jī)，有效節(jié)省電量。它還能顯示低電壓提示，提醒用戶及時更換電池。轉(zhuǎn)速表可以保留最大值、最小值和平均值，方便用戶進(jìn)行數(shù)據(jù)記錄和分析。

在技術(shù)參數(shù)方面，AZ8000的量程范圍為10~99999轉(zhuǎn)速RPM，分辨率為0.001/0.01/0.1/1RPM，準(zhǔn)確度達(dá)到0.04% ±2dgts。其反應(yīng)時間為1秒（>60rpm），在10~60rpm時反應(yīng)時間大于1秒。采用LCD顯示，可清晰顯示五位數(shù)的測量結(jié)果。尺寸為124（L）x50（W）x33（H）mm，重量僅為140g，便于攜帶和使用。供電電源為9V電池，附件包括紙盒、電池、反光帖紙和使用說明書。

該轉(zhuǎn)速表適用于多種場景，如汽車、摩托車生產(chǎn)制造及維修，可用于測量引擎馬達(dá)的轉(zhuǎn)速；在家用電器生產(chǎn)制造及維修中，可測量風(fēng)扇馬達(dá)的轉(zhuǎn)速；在工廠中，可用于測量電機(jī)、輸送帶等的轉(zhuǎn)速。

The AZ8000 photoelectric tachometer is a non-contact tachometer launched by Taiwan Hengxin Company. It adopts the photoelectric reflection principle for measurement, obtaining speed information by emitting infrared rays and receiving the reflected rays from the target. The tachometer features non-contact measurement, which can avoid the influence on the measured object caused by contact measurement. It is easy to operate, and even first-time users can quickly get started. The device also has an automatic gear shifting function, which can automatically switch ranges according to different measurement requirements. In addition, the tachometer will automatically shut down after 20 minutes of inactivity, effectively saving power. It can also display low voltage prompts to remind users to replace the battery in time. The tachometer can retain the maximum, minimum, and average values, facilitating data recording and analysis for users.

In terms of technical parameters, the AZ8000 has a measuring range of 10~99999 RPM, with a resolution of 0.001/0.01/0.1/1 RPM and an accuracy of 0.04% ±2dgts. The response time is 1 second for speeds above 60rpm, and greater than 1 second for speeds between 10 and 60rpm. It uses an LCD display to clearly show the measurement results in five digits. The dimensions are 124（L）x50（W）x33（H）mm, and the weight is only 140g, making it easy to carry and use. The power supply is a 9V battery, and the accessories include a paper box, battery, reflective tape, and user manual.

The tachometer is suitable for a variety of applications, such as in the production, manufacturing, and maintenance of automobiles and motorcycles, where it can be used to measure the speed of engine motors; in the production, manufacturing, and maintenance of home appliances, it can measure the speed of fan motors; and in factories, it can be used to measure the speed of motors, conveyor belts, and other equipment.
