產(chǎn)品概述

testo 825-T4是一款多功能紅外溫度測(cè)量?jī)x器，結(jié)合了非接觸式紅外測(cè)溫與接觸式測(cè)溫功能于一體。該設(shè)備采用激光瞄準(zhǔn)技術(shù)，可精準(zhǔn)定位測(cè)量目標(biāo)區(qū)域，并具備聲音報(bào)警功能，當(dāng)測(cè)量值超過(guò)預(yù)設(shè)限值時(shí)自動(dòng)提醒用戶。儀器配備保護(hù)軟套和扣件，便于攜帶且能有效防塵防撞擊。其設(shè)計(jì)符合人體工程學(xué)原理，操作簡(jiǎn)便，適用于工業(yè)維護(hù)、建筑檢測(cè)、暖通空調(diào)等多種場(chǎng)景的溫度監(jiān)測(cè)需求。1321

核心功能特點(diǎn)

testo 825-T4的顯著特點(diǎn)包括可調(diào)節(jié)發(fā)射率（0.20～1.00范圍），能適應(yīng)不同材質(zhì)表面的精確測(cè)量。儀器具備快速響應(yīng)能力，紅外測(cè)溫反應(yīng)時(shí)間僅1秒，接觸式測(cè)溫反應(yīng)時(shí)間為5秒。內(nèi)置雙模式顯示，支持℃/℉單位切換，并具有數(shù)據(jù)保持功能可凍結(jié)測(cè)量讀數(shù)。激光標(biāo)識(shí)點(diǎn)幫助用戶精確定位測(cè)量區(qū)域，而聲音報(bào)警功能則確保重要溫度閾值不被忽略。設(shè)備采用2節(jié)AAA微型電池供電，續(xù)航時(shí)間達(dá)20小時(shí)，滿足長(zhǎng)時(shí)間作業(yè)需求。82028

技術(shù)參數(shù)

該設(shè)備紅外測(cè)溫范圍為-50.0°C至+400.0°C（-60.0°F至+750.0°F），接觸式測(cè)溫范圍為-50.0°C至+250.0°C。在-50.0°C至100.0°C范圍內(nèi)精度為±2.0°C，100.1°C至400.0°C范圍內(nèi)精度為±2%測(cè)量值。儀器尺寸為43.4×184.0×19.0mm，重量?jī)H80克，緊湊輕便。工作溫度范圍為0.0°C至50.0°C，存儲(chǔ)溫度范圍為-40.0°C至70.0°C，適應(yīng)多種環(huán)境條件。212230

應(yīng)用場(chǎng)景

testo 825-T4廣泛應(yīng)用于建筑物表面溫度檢測(cè)（如墻面、天花板）、工業(yè)設(shè)備維護(hù)中的高溫部件監(jiān)測(cè)、食品加工過(guò)程的溫度控制，以及暖通空調(diào)系統(tǒng)的性能評(píng)估。其兩用設(shè)計(jì)特別適合需要快速篩查表面溫度后進(jìn)一步精確測(cè)量的場(chǎng)景，例如在食品安全檢測(cè)中先進(jìn)行非接觸式篩查再對(duì)異常區(qū)域進(jìn)行接觸式復(fù)測(cè)。配套的反射標(biāo)貼（選配）可提升光滑金屬表面的測(cè)量準(zhǔn)確性。61725

English Product Introduction

The testo 825-T4 is a dual-mode infrared thermometer combining non-contact and contact temperature measurement capabilities. Equipped with laser targeting and audible alarm functions, this compact device provides accurate temperature readings from -50.0°C to +400.0°C (-60.0°F to +750.0°F) for infrared measurements and -50.0°C to +250.0°C for contact measurements. Its adjustable emissivity (0.20-1.00) ensures reliable readings on various surface materials.320

Key Features

This handheld instrument features rapid 1-second response time for infrared measurements and 5-second response for contact measurements. The built-in laser pointer precisely identifies measurement areas, while the overload alarm immediately notifies users when temperature limits are exceeded. The unit includes a protective soft case and clip for easy portability, with ergonomic design allowing one-handed operation. The backlit display shows real-time readings with ℃/℉ toggle function, and data hold feature freezes measurements for documentation. Powered by 2 AAA batteries offering 20 hours continuous operation.82130

Technical Specifications

The testo 825-T4 delivers ±2.0°C accuracy from -50.0°C to 100.0°C and ±2% of reading above 100.1°C. The compact dimensions (184×43.4×19mm) and lightweight (80g) design facilitate field use. Operating temperature range is 0.0°C to 50.0°C with storage range of -40.0°C to 70.0°C.
