ph室內空氣質量檢測

一、 ph室內空氣質量檢測儀器的用途

PHS型數顯酸度計是用于實驗室測量PH值的高精度儀器。具有PH、MV雙重功能,標配E201-C復合電極,反應快,穩定性好。儀器適用于工礦企業、科研、農業、醫藥、教學、環保等單位,用于取樣測定水溶液的pH值和測量電極電位(mV值)。是武漢空氣檢測實驗室非常有用的基礎設備。

室內空氣質量檢測出具cma甲醛檢測報告的才是最權威的

二、ph室內空氣質量檢測技術指標型號

技術參數PHS-25
    
儀器級別0.1級
    
測量參數pH值、mV(ORP)
    
測量范圍pH(0.00~14.00)pH
mV(-1400~1400)mV
    
分辨率pH0.01pH
mV1mV
    
基本誤差pH±0.05pH±1個字
mV±1%FS
    
穩定性(±0.05pH±1個字)/3h
    
儀器功能
    
溫度補償手動(0.0~60.0)℃

標定二點標定(指針一點標定)
    
顯示LCD 指針
    
電源數顯:DC 9V

指針:AC(220±22)V,(50±l)Hz


 
三、 ph室內空氣質量檢測儀器的使用環境:

(1)環境溫度:5~40℃;

(2)相對濕度:≤80%;

(3)被測溶液溫度:5~60℃;

(4)供電電源:220V/50Hz電源

(5)無顯著的振動,及強電磁場干擾。


四、 ph室內空氣質量檢測儀器主要部件及功能

定位旋鈕:校準時根據相應溫度調節pH6.86標準緩沖液的值.

溫度旋鈕:設定待測溶液的溫度值.

斜率旋鈕:校準時根據相應溫度調節pH4.00或pH9.18標準緩沖液的值.

電極插口:連接pH復合電極(接口型號:Q9)

pH/mV轉換開關:選擇測量pH值或mV值

  電源開關:打開或關閉儀器電源

  電源插座:連接穩壓電源適配器,或電源線

室內空氣質量檢測一定要找專業有cma甲醛檢測資質的機構
