At ~16" these thickness gages have the largest throat depth we can offer. The inch or metric reading gage is designed for measurement of relatively soft materials such as felt, foam, elastics, leather, plastics and other compressible fabrics. (For harder substances see models at bottom of this page.) Shown with optional weights to increase measuring force.
The extra large 30 mm diameter flat anvils allow a precise measurement to be taken without unduly compressing the material. If, for some reason you prefer a smaller anvil, this will have to be specified at the time of ordering.
There is no extra charge for different sized anvils.
The anvils are closed when at rest. Depressing the lever causes the anvil to rise, which allows you to insert the material to be measured. The anvil closes under its own weight which is constant from one measuring sample to the next. The measuring force is 1.2 N but can be customized. You will have to request a custom measuring force when the order is placed. Additional measuring force can be added with weights placed above the indicator. These weights as shown in the photo above are optional.
A word of caution: when operating the lever, make sure you do not rest your hand on the gage frame. Even though the frame is made of aluminum, a slight amount of pressure on the frame can cause reading errors of several thousandths. Try it and you will see.
