ST-622直板式紅外測(cè)溫儀是一款由中國(guó)臺(tái)灣先馳（SENTRY）生產(chǎn)的非接觸式測(cè)溫工具。其測(cè)量范圍為-32~535℃（-25~999℉），距離系數(shù)為12:1，能夠滿足多種場(chǎng)景的測(cè)溫需求。該測(cè)溫儀采用四位背光LCD顯示器，可清晰顯示測(cè)量結(jié)果。其具備掃描、鎖機(jī)、自動(dòng)功能，以及約6秒后的自動(dòng)關(guān)機(jī)功能，方便用戶操作并節(jié)省電量。此外，該測(cè)溫儀還支持?jǐn)z氏/華氏溫度切換、背光顯示、激光測(cè)量等功能，可幫助用戶更準(zhǔn)確地進(jìn)行目標(biāo)瞄準(zhǔn)和溫度測(cè)量。其熱放射率可調(diào)，能夠適應(yīng)不同材質(zhì)的測(cè)溫需求。該測(cè)溫儀的重復(fù)性為±1℃，準(zhǔn)確度在不同溫度區(qū)間分別為：-32~ -20℃時(shí)為±3℃，-20~100℃時(shí)為±2℃，100~535℃時(shí)為±2%。其操作溫度為0~50℃，相對(duì)濕度10~90%，能夠在較為廣泛的環(huán)境條件下正常工作。該測(cè)溫儀尺寸為205×62×55mm，重量約232g，便于攜帶和使用。其標(biāo)準(zhǔn)配件包括9V電池、說明手冊(cè)和便攜盒。

The ST-622 straight plate infrared thermometer is a non-contact thermometer produced by Sentry from Taiwan. It has a measurement range of -32 to 535℃ (-25 to 999℉) and a distance coefficient of 12:1, which can meet the temperature measurement needs of various scenarios. The thermometer features a four-digit backlight LCD display that can clearly show the measurement results. It also has functions such as scanning, locking, automatic operation, and automatic shutdown after about 6 seconds, which makes it convenient for users to operate and saves power. In addition, the thermometer supports switching between Celsius and Fahrenheit, backlight display, and laser measurement, which can help users aim at the target and measure temperature more accurately. Its emissivity is adjustable, which can meet the temperature measurement needs of different materials. The repeatability of the thermometer is ±1℃, and its accuracy is ±3℃ in the range of -32 to -20℃, ±2℃ in the range of -20 to 100℃, and ±2% in the range of 100 to 535℃. The operating temperature of the thermometer is 0 to 50℃ with a relative humidity of 10 to 90%, allowing it to work normally in a wide range of environmental conditions. The thermometer measures 205×62×55mm and weighs about 232g, making it easy to carry and use. The standard accessories include a 9V battery, a user manual, and a carrying case.
