以下是AR300紅外線測溫儀/AR-300的產(chǎn)品中英文介紹：

AR300紅外線測溫儀是一款功能強(qiáng)大的非接觸式測溫工具，廣泛應(yīng)用于工業(yè)、科研、日常檢測等多個(gè)領(lǐng)域。它通過紅外感應(yīng)和光學(xué)原理，能夠快速、準(zhǔn)確地測量物體表面溫度，無需與被測物體直接接觸。該測溫儀的測溫范圍為-32℃至400℃，測量精確度在不同溫度區(qū)間有所不同，-32℃至0℃時(shí)為±3℃，0℃至100℃時(shí)為±2℃，100℃以上為±2℃或±2%。其測量物距比為12:1，發(fā)射率可在0.10至1.00之間調(diào)節(jié)，分辨率高達(dá)0.1℃/0.1℉。此外，它還具備多種實(shí)用功能，如℃/℉單位轉(zhuǎn)換、數(shù)據(jù)鎖定、激光定位、背光顯示以及自動(dòng)關(guān)機(jī)功能。該設(shè)備采用9V電池供電，產(chǎn)品凈重僅108g，尺寸為150×89×34mm，便于攜帶和操作。

The AR300 infrared thermometer is a powerful non-contact temperature measurement tool, widely used in industrial, scientific research, and daily inspection fields. It can quickly and accurately measure the surface temperature of objects without direct contact, based on infrared sensing and optical principles. The thermometer has a temperature measurement range of -32℃ to 400℃. The measurement accuracy varies in different temperature ranges: ±3℃ from -32℃ to 0℃, ±2℃ from 0℃ to 100℃, and ±2℃ or ±2% above 100℃. It features a distance-to-spot ratio of 12:1, an adjustable emissivity from 0.10 to 1.00, and a resolution of 0.1℃/0.1℉. In addition, it is equipped with multiple practical functions, including ℃/℉ unit conversion, data lock, laser targeting, backlight display, and automatic shutdown. Powered by a 9V battery, the product weighs only 108g and has dimensions of 150×89×34mm, making it easy to carry and operate.
