Monitor hydraulic fluid or oil level in pressurized applications, such as hydraulic systems where overflow is a concern.

Made with clear, shatter-resistant plastic, these indicators don't require a shield to protect them like other oil-level indicators, so you can check your hydraulic fluid or oil level from any angle.

Check the level of liquids containing chemicals such as alcohol-based solutions, boric acid, and sodium bicarbonate.

Check both the temperature and the hydraulic fluid or oil level in a pressurized system.

Shut-off valves stop flow so you can clean and replace gauge glass without removing these indicators from your equipment.

Monitor liquid level in applications that have vibration, high pressures, and high temperatures. These indicators are also known as armored level gauges.

Use this gauge glass with heavy duty level indicators.

Avoid overfilling—these indicators pop up when your tank is almost full.

Use these gaskets with heavy duty level indicators to seal the glass.

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

View tank contents from multiple angles through the plastic domed window.

Continuously monitor oil quality through the clear plastic reservoir, and use the attached drain valve to remove water accumulation.

Often used in kilns and other heating equipment, these sights have a quartz window that can withstand temperatures up to 1600° F. They're also known as peep sights.

Press these sights into a hole in your tank wall; no additional mounting nuts are needed. They mount from the outside.

Weld these sights to single-wall tanks.

Designed with quick-clamp (KF) connections, these sights connect to a port on a high-vacuum chamber, so you can monitor what's happening inside.

With a stainless steel float and float rod, these gauges resist corroding from chemicals.

Mount these gauges on the flat end of a horizontal, cylindrical tank to monitor diesel fuel, fuel oil, or gasoline level.

Measure water, hydraulic fluid, or diesel fuel level in your drum.

Also known as level loggers, level sensors, and pressure transducers, these transmitters sit at the bottom of your tank in applications that make traditional mounting difficult.

Fold these vertical rulers for convenient storage and transport.

Connect continuous segments to create a ruler up to 10 ft. long.

Also known as oil-gauging tapes, use these tape measures to check the level of oil and other fluids in deep, large containers such as tanks and vats.

Reach deep into small holes and slots for precise depth measurements.

These gauges come with a calibration certificate traceable to NIST that states they've passed a test for accuracy.

Measure depth in dusty or wet environments--these gauges are rated IP67 for protection from dust and temporary water submersion.

These gauges come with a calibration certificate traceable to NIST that states they've passed a test for accuracy.

Check measurements at a glance.

Measure oil as it's dispensed.

Connect these dispensing stations to your bulk oil container to easily fill hand-held dispensers.

These are the most commonly used pressure gauges. Use them with pumps, filters, regulators, and in process lines to measure and display pressure.

Gauges come in a variety of colors so you can identify an important spot in your process line.

Measure small pressure changes in ventilation systems, hydraulic applications, and other critical processes.

A digital display allows for easy reading of measurements.

Unlike other gauges that have multiple moving parts that can shake loose, these have only one internal part. They are the most shock-resistant gauges we offer.

Gauges have an accuracy of ± 2%.

These gauges have a unique case design that eliminates the air bubble on the dial face, which can distort readings. They have a liquid-filled dial that reduces needle flutter for precise readings in high-vibration applications.

These gauges can withstand both extremely cold and extremely hot temperatures.

Gauges have an accuracy of ± 0.5% to ± 1%. They are suitable for critical processes that require high accuracy, such as hydraulic and laboratory applications.

These gauges have a liquid-filled dial that reduces needle flutter in high-vibration applications reaching 2,000 psi.

Use these gauges to monitor the pressure of compressed gas.

Gauges are UL 393 listed for use with fire-protection service equipment.

A liquid-filled dial reduces needle flutter in high-vibration food-processing applications.

Use in low-pressure applications up to 160 psi.

Test and calibrate transmitters, gauges, and other equipment that measures pressure.

With an accuracy of ±0.05%, these have the highest accuracy of all our test gauges.

All-stainless steel construction makes these gauges suitable for testing and calibrating in corrosive environments.
