Trying to find out the preferred laser tach being used in vibration programs. I have the entek 198 that has worked very well with our CSI 2120. We had an accident with the 198 and need to either have it repaired our purchace a new one.
Thanks for any input, Scott

The IRD 198 was a good old tach. Not sure if they are still available. CSI has their own laser tach that is desireable. We also provide a Smart Laser Tach - for information and pricing:
