中文介紹： AZ8351/AZ8361/AZ8371筆式電導(dǎo)率/TDS/鹽度計是臺灣衡欣公司推出的便攜式水質(zhì)檢測儀器，具有多種實用功能和特點。該系列儀器采用筆式設(shè)計，便于攜帶和操作，適合在不同場景下快速測量水質(zhì)參數(shù)。其外殼符合IP65防水標(biāo)準(zhǔn)，能夠有效防止灰塵和水濺，確保儀器在潮濕環(huán)境中的穩(wěn)定性。

AZ8351型號主要測量電導(dǎo)率，范圍為0~1990μS或0~19.9mS，適用于檢測水溶液的導(dǎo)電性。AZ8361型號則專注于測量總?cè)芙夤腆w（TDS），其測量范圍為0~1999ppm或0~19.99ppt，能夠幫助用戶了解水中溶解物質(zhì)的總量。而AZ8371型號用于測量鹽度，范圍為1.0~70.0ppt（以氯化鈉為基準(zhǔn)），適合水產(chǎn)養(yǎng)殖、食品加工等行業(yè)。

這三款儀器均具備手動或自動溫度補償功能，能夠根據(jù)環(huán)境溫度變化自動調(diào)整測量結(jié)果，確保測量的準(zhǔn)確性。此外，它們還配備了低電量指示、數(shù)據(jù)鎖定功能以及20分鐘無操作自動關(guān)機功能，方便用戶使用。儀器的LCD顯示屏可同時顯示兩種數(shù)據(jù)，便于用戶快速讀取。

英文 Introduction: The AZ8351/AZ8361/AZ8371 pen-type conductivity/TDS/salinity meters are portable water quality testing instruments launched by AZ Instrument from Taiwan. They are designed with multiple practical functions and features. The pen-style design of these instruments makes them easy to carry and operate, suitable for quickly measuring water quality parameters in various scenarios. The instruments have an IP65 waterproof housing, which effectively prevents dust and water splashes, ensuring stability in humid environments.

The AZ8351 model mainly measures conductivity, with a range of 0~1990μS or 0~19.9mS, and is suitable for detecting the conductivity of aqueous solutions. The AZ8361 model focuses on measuring total dissolved solids (TDS), with a range of 0~1999ppm or 0~19.99ppt, helping users understand the total amount of dissolved substances in water. The AZ8371 model is used for salinity measurement, with a range of 1.0~70.0ppt (based on sodium chloride), and is suitable for industries such as aquaculture and food processing.

All three models are equipped with manual or automatic temperature compensation functions, which can automatically adjust measurement results according to changes in ambient temperature to ensure accuracy. In addition, they have low battery indicators, data lock functions, and an auto-shutoff feature after 20 minutes of inactivity, making them convenient for users. The LCD display of the instruments can show two types of data simultaneously, facilitating quick reading.
