Control of Liquids, Gases, and Solids

Vibration-Resistant Pressure Gauges

A liquid-filled dial reduces needle flutter for precise readings in high-vibration applications.

Absolute Pressure Gauges

Unlike other gauges that measure the difference between your system and the atmosphere, these give measurements relative to zero pressure.

Flush-Mount Pressure Transmitters

The diaphragm on these transmitters mounts flush with your system’s connection, leaving no room for thick liquids to clog or harden. They’re often used to monitor pressure in wastewater, paint, and adhesive-dispensing applications.

Pressure and Vacuum
Transmitters with Digital Display

Monitor and control vacuum pumps, air compressors, and hydraulics while viewing readings and warnings on the display.

Shatter-Resistant Sights

The window and body are made from a single piece of plastic, making these sights more shatter resistant than sights with a glass window.

Sights

These sights have a glass window.

Any-Orientation Flowmeters

A spring piston instead of a float allows these flowmeters to measure flow rate in any mounting orientation.

Dimensional Measuring and Size Checking

Threaded Plug Gauges with
Handle for Pipe Threads

Verify whether pipe fitting threads fall within tolerance. These gauges are attached to a handle, giving you a solid gripping point to thread and unthread them quickly.

Threaded Ring Gauges for Pipe
Threads with Calibration Certificate

These gauges come with a certificate that’s traceable to NIST, confirming they were calibrated in a lab. Use them to verify whether external pipe threads are within tolerance.

Threaded Ring Gauges for Pipe Threads

Confirm that external pipe threads are sized within tolerance.

Thread Identifier Sets

Set includes calipers and gauges to identify external and internal threads
