儀器的人性化設(shè)計進(jìn)一步提升了操作體驗。機(jī)身采用防滑材質(zhì)，符合人體工學(xué)握持；探頭可通過磁性固定裝置吸附于金屬表面，解放雙手進(jìn)行多點測量。內(nèi)置數(shù)據(jù)存儲功能可記錄多達(dá)500組測量值，支持通過USB或藍(lán)牙（選配）傳輸至電腦或移動端，便于后續(xù)分析或生成報告。此外，低功耗設(shè)計和長續(xù)航電池保障了連續(xù)8小時以上的高強(qiáng)度使用需求。

Testo 425廣泛適用于樓宇通風(fēng)系統(tǒng)檢測、潔凈室壓差監(jiān)控、工業(yè)排風(fēng)效率評估等場景。其堅固外殼符合IP54防護(hù)等級，可應(yīng)對粉塵、潮濕等復(fù)雜環(huán)境。搭配可選配件如延長軟管或三角支架，可進(jìn)一步擴(kuò)展測量場景，滿足多樣化需求。無論是技術(shù)人員現(xiàn)場調(diào)試，還是實驗室環(huán)境研究，Testo 425均能提供可靠數(shù)據(jù)支持，助力用戶提升工作效率。

‌Testo 425 Thermal Anemometer Product Introduction (English)‌
The Testo 425 is a professional-grade thermal anemometer designed for precise measurement of airflow velocity, temperature, and volume flow, ideal for HVAC system commissioning, environmental monitoring, and industrial equipment maintenance. Utilizing advanced thermal probe technology and intelligent algorithms, it delivers rapid response and high accuracy, empowering users to optimize ventilation systems and assess indoor air quality with efficiency.

The Testo 425 excels in portability and versatility. Equipped with an extendable probe, it covers a measurement range of 0 to 20 m/s with a resolution of 0.01 m/s, ensuring precise detection of subtle airflow variations. The integrated temperature sensor supports simultaneous measurements from -20°C to +70°C, with real-time data displayed on a high-contrast LCD screen for instant readability. The volume flow calculation feature further simplifies data analysis by automatically deriving flow rates based on user-input cross-sectional dimensions.

User-centric design enhances operational convenience. The ergonomic housing with anti-slip grip ensures comfortable handling during prolonged use, while the magnetic probe mount allows hands-free fixation on metal surfaces for multi-point measurements. With onboard memory storing up to 500 data sets, users can transfer readings via USB or optional Bluetooth to PCs or mobile devices for report generation. The long-lasting battery provides over 8 hours of continuous operation, meeting demanding field requirements.

Suitable for building ventilation inspections, cleanroom pressure monitoring, and industrial exhaust efficiency evaluations, the Testo 425 boasts a rugged IP54-rated housing resistant to dust and moisture. Optional accessories such as flexible hoses or tripods extend its applicability across diverse scenarios. Whether for on-site technician diagnostics or laboratory research, the Testo 425 delivers reliable data integrity, enabling professionals to achieve higher productivity and informed decision-making.
