went to harbor freight today to see if they have 845 left, they didnt. so i got some stuff and went to check out. noticed that they had cen-tech paint thickness gauge there in glass case. couldnt belive the price: $9.97 (no not 99.70, you read it right $10). so i grabed it
Test.
Cen tech
calibrated it with provided foil (was dead on accurate before calibration)
Accuracy
Math
((Reading - Plastic Shim Preordained Measurement) x 100) - 100 = Percentage over Plastic Shim Preordained Measurement
first reading Cen-tech. second reading HL II

Average Percentage= -2.4% @ 505 microns
Speed
Takes about 2 seconds to take one reading.
Ergonomics
Lightweight, fits easily in hand but you have to pull triger to take reading and hold it till it takes it. would have been better if it had ring around probe like Highline II. but does have blue light if you doing something in dark
Price
Cost me $9.87 plus tax (not available online (left over stock clearance) .
Final Thoughts
For $10 gauge, thats a hell of a deal and id say it is more accurate then HL II, WTF? and costs $210 less maybe something wrong with my HL II?
