<< We recommend the use of deionized water in all aqueous cleaning operations.
 For us, deionized water is 2.0 megohm-centimeters of resistivity or higher.
 Being metrically challenged, I am not sure what that is in microsiemens per
 centimeter.

Good Mornin' All!

Here's a little chart to convert resistance into microsiemens:


Deionized Water Resistance in Megohm                Equivalent readout in 
µS/cm 
1 Mohm                                      1.000 µS/cm 
2 Mohm                                      0.500 µS/cm 
5 Mohm                                      0.200 µS/cm 
10 Mohm                                         0.100 µS/cm 
15 Mohm                                         0.067 µS/cm 
20 Mohm                                         0.050 µS/cm 
50 Mohm                                         0.02 µS/cm
