PH30  酸堿度測試計

實驗室里一毫升的水樣測試，野外水源的 pH 測定，紙張和皮膚的酸堿度測量。
PH30 酸堿度測試筆可以滿足您不同的測量需求，體驗測試的樂趣。

產品特點：

●   IP67 防水結構。操作簡易，單手完成精確 pH 值測量。                                                                 

●   廣泛應用場合：滿足實驗室內 1ml 的微量樣品測量到野外的水質檢測。                                      

●   可以進行拋投水質測量（自動鎖定功能）。                                                                                              

●   平面電極可用于皮膚或紙張 pH 值測量。                                                                                            

●   使用者可自行更換的高阻抗平面電極。                                                                                                 

●   MHX4 組件結構設計，堅固防水，握持舒適。                                                                                    

●   維護簡單，無須任何工具可輕易更換電池和電極。                                                                             

●   1-5 點，zui多 5 點自動校準，有效避免各量程誤差。                                                                       

●   自動識別 7 種標準溶液，涵蓋 USA 與 NIST 標準系統。                                                              

●   多行大屏 LCD，同時顯示各種工作數據。                                                                                           

●   屏幕儲能背光，方便暗處讀值。                                                                                                             

●   電極效能狀態自我診斷顯示。                                                                                                                 

●   一節 AAA 電池，使用壽命超過 500 小時，經濟方便。                                                                   

●   無按鍵動作后 6 分鐘自動關機。
