23DDG MiniGauge

Brand: Ashcroft Inc
Does not ship to Virginia, United States

In the world of compact operating systems, microcomputer chips, miniature pneumatics and general equipment downsizing, Ashcroft instruments are keeping up with the times.

The Ashcroft MiniGauge is designed for those applications where space is a limiting factor.

At 23 mm, the compact MiniGauge is smaller than 1" in diameter and available in 60 psi through 300 psi ranges.

Taking into consideration the small size of the MiniGauge, the dial face was designed for maximum readability. This product is offered in 1/8" NPT back connection with 15 mm (9/16") wrench flats for easy installation.

The versatile Ashcroft MiniGauge surpasses the demands of durability in two important ways: first, by using direct drive reading, the spiral tube transmits motion directly to the pointer - no gears or movement parts to wear out; and second, the case material is an ABS blend that is both enduring and attractive.

The Ashcroft MiniGauge is ideal for a multitude of applications where a 1-1/2" conventional size gauge is too large.
