Rex platinum black / light sensor probe electrode conductivity meter DJS-10C conductivity meter common electrode

Selection 1. Common specifications constant electrode conductivity electrode (J0) there are four: 0.01, 0.1. Selection of the specifications of the conductivity electrode should be based on the measured liquid medium conductivity range may be. Four sizes of conductivity electrode, its adaptation to the conductivity measurement range include: ◆ When the conductivity value measured solution should be less than 20us / cm selection DJS-1C type bright electrode, when the conductivity is higher than this value, should be used DJS-1C platinum black electrodes. Should ◆ When the measured conductivity of the solution is higher than 20ms / cm selection DJS-10C type electrode, then expand 10-fold range. 20ms / cm profile can be measured to 200ms / cm. ◆ When the conductivity of less than 2us / cm, should be used in constant DJS-0.1 electrodes. For example: measuring water or high water. ◆ When conductivity less than 0.1us / cm, should be used in constant electrode DJS-0.01. For example: 2. ultrapure water measuring instrument range display the scope of the instrument has a fourth gear range. Table 2 J0 = 1 时 each range segment display range corresponding to the range number range switch position measuring range of usable specifications constant electrode 1 20uS 0.001 ~ 19.99 uS / cm 0.01 0.1 1 2 200uS 0.1 ~ 199.9 uS / cm 1 3 2mS 1 ~ 1999 uS / cm 1 4 20mS 10 ~ 19990 uS / cm 1 10 Note: Range 2 files, the unit uS; when the range 3,4 file, the unit mS choose other specifications constant electrode, which range display reading: K = D × JK: measured liquid conductivity D: instrument displays the value J: constant conductivity electrode Specifications
