Why buy the LE1000-2 thickness gauge? Quite simply... The most accurate thickness gauge you will find A Low Force model with only 12g of force is available… essential for soft materials Used by Research Laboratories and countless companies throughout the World Extraordinary accuracy  (< 0.2 µm)  will save you money! No non-linearity Low cost Why ACCURACY Matters... NOT RESOLUTION! ACCURACY vs RESOLUTION:  Resolution is like sensitivity, it is the smallest possible change of the parameter that can be detected. Accuracy on the other hand is a deviation between the measured and the "true" value. In other words, the accuracy can be described as a maximum operating error that is intrinsic or can be expected under all conditions. The accuracy and the resolution are not the same, though they can be measured in the same units. For example, a thickness gauge can have a resolution of 1 um, while the accuracy of the results can typically be 3 - 10 times (or 3 - 10 um) worse. The LE1000-2 gauge has an Accuracy of better than 0.2 µm and a significant portion of the range is typically better than 0.1 µm. Most other gauges can only approach a 1.0 µm Resolution, and that "Resolution" number means very little since the gauge "Accuracy", as noted above, is typically a multiple of the resolution. In the example below, we compared the LE1000-2 to a gauge having 1.0 µm resolution. A 1.0 µm resolution gauge can have an Accuracy anywhere from ± 2 µm to 5 µm. We chose the best case, ±2 µm. Even at this accuracy, our gauge is 1.8 µm more accurate, so the possible "acceptable" error difference is 1.8 µm. This means you could be measuring 1.8 µm thinner than the "true" material thickness is, while still remaining within the acceptable gauge error, and you would never know it. Once again, wasting material and risking customer complaints. The lower portion of the example shows the huge impact of these small, often overlooked, issues. If you produce plastic, paper, foil, or any compressible product, this gauge is the best tool you can have to save you money and improve your quality. If you don't know exactly what you are making, you can't improve your process and maximize your profit. This is a "must have" tool for every plastic film manufacturer. A simple example Gauge Force / Compression Test:  The above test results demonstrate the effect of "force" on a typical thickness measurement. Most contact gauges have a force of 0.6N to 1.5N (60 gr to 150 gr). We took our LE1000-2 and applied a 0.85N force with a typical measurement tip and measured a 25 µm thick piece of PE film. The gauge measured 22.2 µm. We then took our Low Force (0.12N) LE1000-2 fitted with our low force tip and measured the same piece of film in the same spot. The gauge now read 24.8 µm; an increase of 2.6 µm. This increase was entirely due to the decrease in measurement force. Or, to put it another way... with a higher force gauge, there was a 2.6 µm material LOSS due to measurement force compression. If you were using the "other" gauge to manufacture your film, you would have needed to increased your material thickness by 2.8 µm to hit your 25 µm target. While in reality, all you needed to do was increase thickness by a mere 0.2 µm. And if that gauge had a normal 2 um possible error this increase could have been as high as 4.8 um.
