hello,


i am think about getting a micron gauge... i seen that they have a tif 9450d micron gauge that reads down to 200 micron for $200.00

Then i see another one ( not sure of manufacter ) and reads down to 10 microns.. This one cost less... So why would the one that reads lower cost lower.. Is the tif 9450d a good buy??

Any info would be welcome
ryan
