Mahr Inc. has expanded its line of digital depth gages with the pocket-sized 30 EWRi for fast depth measurements, and the universal depth gage 30 EWR-U/40 EWRi-U.

The 30 EWRi is a compact depth gage with a 0.06inch (1.5 mm) contact and one-inch (25 mm) gaging range with integrated wireless data transmission. It is ideal for mobile use in manufacturing and inspection at the point of manufacture.

Mahr’s 30 EWR-U universal depth gage includes MarConnect output for wired USB RS-232 or Digimatic while the 30 EWRi-U with integrated wireless data transmission brings new application versatility to depth gage measurements.

Both gages incorporate interchangeable anvils to multiply the measurement capabilities of the gage. The gage also comes with a 30 Ud twin hook anvil standard for measuring basic widths and distances.

Five anvil choices are also optionally available to increase the gages’ measurement capabilities. Measuring depths and recesses with various configurations of ball or chisel-style anvils becomes easier.

Both the 30 EWR-U and 40 EWRi-U come in measuring ranges of 0-12 inches (300 mm) or 0-20 inches (500 mm) and each has resolution of 0.0005 inches (0.01 mm).

All MarCal depth gage products offer IP67 resistance to dust, coolants and lubricants, and feature high-contrast digital display, locking screw, zero reset function, and reference system for retaining zero immediate measurement readout.

Integrated wireless data transmission simplifies the recording and documenting process, especially in the networked factory of Industry 4.0. With the touch of a button on the instrument, keyboard, timer, remote control, or foot switch, acquired data is sent from the gage to an i-Stick radio receiver plugged into the USB port of the computer.
