Summary:

The bottom line: if you have the time and patience to calibrate this unit every time and you're on a budget, go ahead and buy the extech but if you're a large wholesale buyer and need a tool that works in adverse conditions and will be accurate every single time sans-calibration, I suggest you look elsewhere. For me, the search continues.

Extech-CG204-Coating-Thickness-Tester

PAINT METER PROS

  1. Cheap, actually about 25% the cost of an Elcometer
  2. Screen easy to read
  3. Stores values (not very useful to me, but I can see the benefit)
  4. Compact and easy to carry
  5. Accurate when calibrated
  6. Come with a belt-mounted pouch
  7. Will automatically switch between Steel and Aluminum (Fe and NFe)
  8. Has an alarm that you can set for a minimum or maximum threshold (not sure how many people will use this, seems gimmicky to me)

PAINT METER CONS

  1. Requires calibration after every usage. Let me elaborate, for some reason, the paint meter loses its calibration within 5 minutes of usage or after you turn it off.
  2. Requires calibration when switching between ferrous to non-ferrous body panels
  3. Will default to micro-meters after turning off (I prefer using mils as my unit of measurement)
  4. Too many buttons
  5. Confusing instructions and menus
  6. Has a USB port but the software does not work on a Mac and it’s hard to figure out
  7. Does not seem very durable
  8. Does not come with a wrist band
  9. The measuring bezel is hard plastic and may scratch surfaces (others are rubberized)

I measured thicknesses using Elcometer and compared it to the Extech, they were within 1% of each other.
