Advantages
|
・The measured value of the pH meter/ORP is displayed in a graph on the LCD screen. The scale display width and sampling intervals can be changed.In addition, it is also possible to re-display previous data by scrolling. The data displayed are: time and pH meter/ORP value. |
| ・By connecting a pulse flow meter, it is also possible to display the total accumulated value. |
|
・The measured data are stored in the internal memory normally at intervals of 10 seconds(the intervals can be changed between 5 and 99 seconds). |
|
・If the attached software is installed onto a personal computer, the data can be taken out onto Microsoft Excel. (Connection: RS-232C）.The data that can be taken out are: Year, Month, Day, Hour, Minute, pH meter/ORP, Temperature, and Accumulated flow rate (continuous communication cannot be done). |
| ・LCD with backlight that is easy to see both at daytime and at night. |
|
・The waterproof construction that enables outdoor use is IP54 or equivalent. |
| ・2 relay contact outputs are available which are used for controlling the chemical injection pump for pH meter/ORP control. |
| ※Microsoft Excel is a registered trademark or trademark of Microsoft Corporation of USA in USA and other countries. |
Applications
| ・pH neutralization or oxidation/reduction treatment of drainage in the chemical industry, etc. |
| ・Incorporation of the apparatus of each process. |
| ・pH measurement and control in hydroponic culture, etc. |
| ・pH measurement and control of drainage from cleaning. |
| ・pH measurement and control for drainage from experiments, etc. |
