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.

Monitor hydraulic fluid or oil level in gear boxes, crank cases, and other reservoirs.

Simultaneously monitor the hydraulic fluid or oil level and temperature in gear boxes, crank cases, and other reservoirs.

Easily view liquid movement and level changes from a distance—these sights have an indicator ball inside the glass window.

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

If the oil in your line is too hot or pressurized for standard flowmeters, use these flowmeters to measure the flow rate.

Often used to find worn components or leaks, these flowmeters have a valve, so you can test the flow of oil from pumps and other equipment at different pressures.

The low-profile body fits in areas with limited clearance.
