Paint Thickness Gauge Meter Fe/NFe Probe Coating Thickness Gauge Professional Multifunctional Car Paint Depth Gauge Test Precise HW-300PRO for Car Automatic Detection(black) (white)

Very easy to use and good quality. Gives consistent results.

Let's be honest it's still in the box I haven't even put batteries in it yet but it looks kind of cool sitting there.

Excelente producto, confiable

Worked good but was a little small for a big hand.

It did a good job of letting me know when a body panel had been repaired during my recent car search. Totally worth the price!

No I returned it.

I got this device to measure the paint thickness on older cars we would consider for purchase. Comparing the difference in paint thickness on various panels can indicate any number of repairs or repainting performed. It works really well but must first be calibrated correctly which was initially a little confusing. Included in the package are 6 pieces of plastic samples of various thickness from .05mm to 2mm as well as an aluminum plate to place them on for calibration. After performing the 1st initial calibration procedure my unit proved to be very accurate in measuring the paint thickness on various cars. The aluminum plate simulates the cars base metal and the 6 plastic pieces serve to calibrate a range of paint thickness. The calibration process includes : A) Placing the aluminum plate and the 6 plastic samples in order. (You will be placing each thickness of plastic on top of the aluminum to take successive measurements.) B) Putting the device in calibration mode. ( While holding down the "up" key press the Power on key.) It's now ready to sequentially calibrate the aluminum and the 6 pieces of plastic one by one. C) Place the unit on the aluminum plate, wait for the beep and it should read "0" i.e. no thickness. D) Next place each of the 6 plastic pieces one by one on top of the aluminum plate and wait for the beep indicating the thickness measurement has been made. After the total of 7 measurements, Aluminum plate and 6 plastic thicknesses is made The word "End" will appear in the display indicating successful calibration. Note : The unit reads in um, mm and mils (Thousands of an inch) and defaults to um when turning it on. Pushing the "up" button cycles it thru the 3 units, make certain you are reading the correct units. It defaults to mm in the calibration mode as the test samples are in mm. The rest of the instructions are pretty typical and clearly written, the construction is high quality and the unit I received was accurate as far as I could determine on the few cars, a refrigerator, outdoor grill etc. that were sampled. So, highly recommended at it's price point.

Seems to work, but no instructions in the box. The calibration method is not intuitive, and I only got it from reading other people's reviews.
