中文介紹：美國雷泰（Raytek）ST-20紅外測溫儀是一款性能卓越的非接觸式測溫工具。它采用先進(jìn)的紅外測溫技術(shù)，能夠快速、準(zhǔn)確地測量物體表面溫度，測溫范圍為–32℃至535℃。該設(shè)備的光學(xué)分辨率比為12:1，這意味著用戶可以在相對較遠(yuǎn)的距離測量較小物體的溫度。其單點(diǎn)激光瞄準(zhǔn)系統(tǒng)可幫助用戶精確對準(zhǔn)目標(biāo)，背光照明顯示屏則使在昏暗環(huán)境中讀取數(shù)據(jù)變得輕松。此外，ST-20還具備溫度讀數(shù)保持功能，可將測量結(jié)果保持7秒，方便用戶記錄和查看。

英文介紹：The Raytek ST-20 infrared thermometer is an outstanding non-contact temperature measuring tool from the United States. Utilizing advanced infrared temperature measurement technology, it can quickly and accurately measure the surface temperature of objects, with a temperature range of -32℃ to 535℃. The device has an optical resolution ratio of 12:1, allowing users to measure the temperature of smaller objects from a relatively greater distance. Its single-point laser aiming system helps users to precisely target the object, and the backlit display screen makes it easy to read data in dim environments. In addition, the ST-20 features a temperature reading hold function, which can keep the measurement result for 7 seconds, facilitating users to record and view the data.
