可更換，雙結(jié)電極傳感器節(jié)省時(shí)間和金錢
ip67級(jí)的房屋坐落在桌子上，漂浮在水面上
防水phtestr20對(duì)于戶外應(yīng)用非常重要，比如在湖泊和溪流中測(cè)量pH值。為了在水中漂浮，你甚至可以在外殼上附加一條線，便于檢索。Valox®傳感器住房能抵抗大部分化學(xué)物質(zhì)。
pHTestr 20有一個(gè)可更換的傳感器，便于維護(hù)。雙結(jié)電極傳感器處理含硫化物、重金屬和TRIS的廢水和溶液。電極傳感器提供了一個(gè)clog-resistant聚偏氟乙烯®結(jié)和嵌入玻璃燈泡pH值防止破損。
按鍵點(diǎn)擊確認(rèn)操作，并允許訪問(wèn)多種功能。在美國(guó)和NIST標(biāo)準(zhǔn)緩沖器的自動(dòng)緩沖識(shí)別中校準(zhǔn)三個(gè)pH值。附加功能包括自動(dòng)溫度補(bǔ)償(ATC)，保持功能，自動(dòng)關(guān)閉功能，自診斷錯(cuò)誤信息，以及一個(gè)三段電池壽命指示器。
儀表包括保護(hù)塑料儲(chǔ)存箱，lanyard，和電池。|

Versatile, compact design works in a field or laboratory setting

• pHTestr 20 features ±0.01 pH accuracy — suitable for most ASTM and EPA test procedures.
• A complete meter with key features at an economical price
• Replaceable, double-junction electrode sensors save time and money
• IP67-rated housing sits flat on the table and floats in water

• Waterproof pHTestr 20 is great for outdoor applications such as taking pH measurements in lakes and streams. Designed to float in water, you can even attach a line to the housing for easy retrieval. Valox® sensor housing resists most chemicals.
  
  The pHTestr 20 has a replaceable sensor for easy maintenance. Double-junction electrode sensor handles wastewater and solutions containing sulfides, heavy metals, and TRIS. Electrode sensor offers a clog-resistant Kynar® junction and a recessed, glass pH bulb to protect against breakage.
  
  The keypad clicks to confirm operation, and allows access to a variety of functions. Calibrate up to three pH points with the auto-buffer recognition at both USA and NIST standard buffers. Additional features include a automatic temperature compensation (ATC), hold function, auto-off function, self-diagnostic error messages, and a three-segment battery-life indicator.
   

  Meter includes protective plastic storage case, lanyard, and batteries.|
