以下是一份臺灣貝克萊斯 BK8621C 溫濕度計的產(chǎn)品中英文介紹：

臺灣貝克萊斯 BK8621C 溫濕度計是一款便攜式、高性能的測量儀器，適用于多種環(huán)境的溫濕度檢測。它采用高精度的 Pt385/1000Ω RTD 溫度傳感器，溫度測量范圍為 -20℃至100℃，解析度可達 0.1℃，在 0℃至50℃的常用溫度區(qū)間內(nèi)，精確度為 ±0.5℃。濕度方面，配備快速反應(yīng)的電容式濕度傳感器，測量范圍為 0%至100%RH，解析度為 0.1%RH，在 25℃、10%至90%RH 的環(huán)境下，精確度為 ±2.5%。

該溫濕度計的顯示屏幕為 3½ 位數(shù)字液晶顯示，即使在光線較暗的環(huán)境中，背光功能也能讓用戶清晰讀取數(shù)據(jù)。此外，它還具備讀值及最大值鎖定功能，方便用戶記錄和對比測量結(jié)果。堅固的防震外殼設(shè)計，使其能夠適應(yīng)各種復(fù)雜的工作環(huán)境，同時附帶攜帶型皮套，便于用戶隨時隨地進行測量。其操作環(huán)境為 0℃至50℃，儲存環(huán)境在 -20℃至60℃、0至80%RH（電池移除后），尺寸為 170mm（高）×44mm（寬）×40mm（厚），重量僅約 160 克（含四顆 1.5V 四號電池），攜帶十分方便，單手即可操作。

The Taiwan Beckles BK8621C hygrometer and thermometer is a portable and high-performance measuring instrument suitable for detecting temperature and humidity in various environments. It employs a high-precision Pt385/1000Ω RTD temperature sensor, with a temperature measurement range from -20℃ to 100℃ and a resolution of 0.1℃. In the commonly used temperature range of 0℃ to 50℃, the accuracy is ±0.5℃. For humidity measurement, it is equipped with a fast-responding capacitive humidity sensor, covering a range from 0% to 100% RH with a resolution of 0.1% RH. At 25℃ and within the 10% to 90% RH range, the accuracy is ±2.5%.

The device features a 3½-digit LCD display, and the backlight function ensures clear data reading even in dimly lit environments. Additionally, it has a readout and maximum value lock function, facilitating users in recording and comparing measurement results. The robust shock-resistant housing design allows it to adapt to various complex working environments. Moreover, it comes with a carrying case, enabling users to conduct measurements anytime and anywhere. The operating environment is from 0℃ to 50℃, and the storage environment is from -20℃ to 60℃, with 0 to 80% RH (after battery removal). The dimensions are 170mm (height) × 44mm (width) × 40mm (thickness), and the weight is only about 160 grams (including four 1.5V AA batteries), making it very portable and operable with one hand.
