以下是一份關(guān)于ST-640紅外測(cè)溫儀的產(chǎn)品中英文介紹：

ST-640紅外測(cè)溫儀是一種非接觸式紅外溫度測(cè)量設(shè)備，具有多種實(shí)用功能。它配備4個(gè)背光數(shù)字LCD顯示屏，具備掃描、鎖定、自動(dòng)測(cè)量以及自動(dòng)關(guān)機(jī)（約6秒）等功能，操作便捷。在測(cè)量時(shí)，只需對(duì)準(zhǔn)被測(cè)物體，扣動(dòng)測(cè)量觸發(fā)器，即可快速讀取溫度。該設(shè)備還具備溫度報(bào)警功能，單束激光用于精準(zhǔn)的目標(biāo)瞄準(zhǔn)，同時(shí)支持外接熱電偶測(cè)量。

ST-640紅外測(cè)溫儀的測(cè)量范圍為-32~535℃（-25~999°F），能夠滿足多種場(chǎng)景下的溫度測(cè)量需求。其測(cè)量精度在不同溫度區(qū)間表現(xiàn)良好，例如在-32℃至-20℃時(shí)精度為±3.0℃，在-20℃至100℃時(shí)精度為±2.0℃，在100℃至760℃時(shí)精度為±2%。此外，該設(shè)備的熱電堆波長(zhǎng)范圍為5~14μm，重復(fù)率為±1℃或2°F，解析度為0.1℃/0.1°F，反應(yīng)時(shí)間為500毫秒。

在設(shè)計(jì)方面，ST-640紅外測(cè)溫儀采用了堅(jiān)固耐用的人體工程學(xué)設(shè)計(jì)，操作舒適，且具有超低電耗，適合長(zhǎng)時(shí)間使用。其背光LCD顯示器在光線較暗的環(huán)境中也能清晰顯示測(cè)量結(jié)果，激光測(cè)量切換功能則進(jìn)一步提高了測(cè)量的準(zhǔn)確性。此外，該設(shè)備還具備攝氏/華氏溫度轉(zhuǎn)換功能，方便用戶根據(jù)需要進(jìn)行切換。

ST-640紅外測(cè)溫儀適用于多種領(lǐng)域，如電力檢修、汽車維修與保養(yǎng)、科學(xué)實(shí)驗(yàn)、生產(chǎn)加工審計(jì)、HVAC能源審計(jì)、電路測(cè)試終端以及電子馬達(dá)及電板狀態(tài)監(jiān)視等。其尺寸為180×65×40毫米，重量為185克，便于攜帶和操作。標(biāo)準(zhǔn)配件包括9V電池、說(shuō)明手冊(cè)和便攜盒。

The ST-640 infrared thermometer is a non-contact infrared temperature measuring device with a variety of practical functions. It is equipped with four backlit digital LCD displays and features scanning, locking, automatic measurement, and auto shut-off (approximately 6 seconds) for convenient operation. To measure, simply aim at the target object and pull the measurement trigger to quickly obtain the temperature.
