性能特點(diǎn)
MaxiDirect采用現(xiàn)代化的設(shè)計(jì),成功的將便攜式光度計(jì)與實(shí)驗(yàn)室光度計(jì)合二為一,是一款既便攜又性能優(yōu)異的產(chǎn)品。
這款儀器涵蓋了從鋁到鋅等所有水質(zhì)分析的重要參數(shù),使用高品質(zhì)的Lovibond®試劑,操作界面友好,保證測(cè)量快速可靠。根據(jù)應(yīng)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(cè)量瓶(16 / 13 mm)。
MaxiDirect內(nèi)置6個(gè)干涉濾光片及長(zhǎng)壽命的LED光源。結(jié)構(gòu)緊湊,整機(jī)無活動(dòng)部件。
MaxiDirect具有存儲(chǔ)功能,可存儲(chǔ)1000組數(shù)據(jù)。可選配紅外接口將數(shù)據(jù)傳輸?shù)诫娔X或是打印機(jī)(RS 232 / USB)。
N.I.S.T. 可追溯性
MaxiDirect的出廠校正報(bào)告是符合國(guó)際標(biāo)準(zhǔn)的,但不遵循N.I.S.T.可追溯性標(biāo)準(zhǔn)。用戶可使用符合N.I.S.T 可追溯性的標(biāo)準(zhǔn)采用“用戶校正模式”校正該儀器。(N.I.S.T.即國(guó)際標(biāo)準(zhǔn)和技術(shù)委員會(huì))
新方法
為滿足市場(chǎng)的需求,檢測(cè)方法會(huì)不斷更新。
計(jì)算公式
借助于外部的數(shù)學(xué)程序,可以通過數(shù)據(jù)對(duì)建立相應(yīng)的計(jì)算公式(濃度/吸光度)。已知的公式已被應(yīng)用。儀器可存儲(chǔ)25條訂制公式(y = A+Bx+Cx2 +Dx3 +EX4 + FX5),相關(guān)參數(shù)可由用戶指定,如波長(zhǎng)、測(cè)量范圍、單位及有效數(shù)字。
濃度
這一功能可用于測(cè)量2到14個(gè)已知標(biāo)準(zhǔn)。根據(jù)已知的濃度/吸光度數(shù)據(jù),儀器可以校正測(cè)量點(diǎn)的線性。樣品測(cè)量可存儲(chǔ)多至10個(gè)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(shí)驗(yàn)室、便攜式測(cè)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.
