Solid cast and painted/coated metal handle. Measuring plates and measuring ruler made of stainless steel. Chrome counter drive lever. The accuracy is within 5 tens of thousands, which is ideal for measuring paper to adjust the press pressure. Easy-to-read display in US and metric units. Uses a standard button cell battery that is easy to replace. It even comes with a foam sleeve to keep it safe. Completely accurate for my specimen of this instrument, measured using a standard Starrett US micrometer with several gauges of sheet metal. I recommend this product.
