性能特點
MaxiDirect采用現(xiàn)代化的設計,成功的將便攜式光度計與實驗室光度計合二為一,是一款既便攜又性能優(yōu)異的產品。
這款儀器涵蓋了從鋁到鋅等所有水質分析的重要參數(shù),使用高品質的Lovibond®試劑,操作界面友好,保證測量快速可靠。根據應用的需要,該儀器可以使用片狀試劑、粉末試劑、液體試劑或是測量瓶(16 / 13 mm)。
MaxiDirect內置6個干涉濾光片及長壽命的LED光源。結構緊湊,整機無活動部件。
MaxiDirect具有存儲功能,可存儲1000組數(shù)據。可選配紅外接口將數(shù)據傳輸?shù)诫娔X或是打印機(RS 232 / USB)。
N.I.S.T. 可追溯性
MaxiDirect的出廠校正報告是符合國際標準的,但不遵循N.I.S.T.可追溯性標準。用戶可使用符合N.I.S.T 可追溯性的標準采用“用戶校正模式”校正該儀器。(N.I.S.T.即國際標準和技術委員會)
新方法
為滿足市場的需求,檢測方法會不斷更新。
計算公式
借助于外部的數(shù)學程序,可以通過數(shù)據對建立相應的計算公式(濃度/吸光度)。已知的公式已被應用。儀器可存儲25條訂制公式(y = A+Bx+Cx2 +Dx3 +EX4 + FX5),相關參數(shù)可由用戶指定,如波長、測量范圍、單位及有效數(shù)字。
濃度
這一功能可用于測量2到14個已知標準。根據已知的濃度/吸光度數(shù)據,儀器可以校正測量點的線性。樣品測量可存儲多至10個方法。
適用范圍
廢水、飲用水、工業(yè)過程用水、科研開發(fā)、政府及第三方實驗室、便攜式測量

Description
This new unit covers all the important parameters of water analysis, from aluminium to zinc. The high level of accuracy of Lovibond reagents and the user-friendly nature of the instrument guarantee rapid and reliable analysis of your water samples. Depending on the application, the unit will operate with tablet reagents, powder packs, liquid reagents or tube tests (16 / 13 mm).
The MaxiDirect operates with 6 interference filters and uses long-life LEDs as a light-source. No moving parts are involved.
Of course, the MaxiDirect has a memory, in which up to 1000 data sets can be stored. The infra-red interface* enables data to be transmitted to a computer or printer (RS 232 / USB). * available as an option : IRIM (infra-red interface module)
Delivery content: The instrument is supplied complete and readyto-use incl. 4 batteries, 3 vials ø 24 mm, 3 vials ø 16 mm, 1 adapter each for 16 mm and 13 mm vials, carrying case with water.
N.I.S.T. Traceability
The instrument has a factory calibration, which is related to internal standards, which are not N.I.S.T traceable. The instrument may be calibrated by the user in a “user calibration mode” with N.I.S.T traceable standards. (N.I.S.T. = National Institute of Standards and Technology)
Datatransmission modul IRiM
The IRiM (infrared interface modul) uses modern infrared technology to transmit measurement data from the MaxiDirect photometer to one of 3 optional interfaces. These interfaces can be used to connect to a PC, a USB printer1) or alternative a serial printer2). The interface which is selected is displayed by an LED function indicator. The user can switch between the interfaces using the „Select“ button.
The unit is supplied complete with data logging software providing easy and rapid transfer of data to the PC. As an option the data can be saved as an Excel sheet or a .txt file. Measurement data can quickly be printed out, using a specified1) USB or alternative severalserial printer2) connected to the IRiM.
