The dial displays measurements in both decimal and fractional increments.

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

Read measurements on a dial or using the two mechanical analog counters.

Small enough to fit between your thumb and index finger, use these Starrett gauges for quick thickness checks on paper, film, and other flat stock.

Check measurements at a glance.

Sets include a Mitutoyo dial caliper, micrometer, ruler, and case.

For monitoring the number of shaft turns on instrumentation, these knobs have easy-to-read scales or digits for quick and accurate readings. Use them on devices with round shafts.

Quickly identify equipment controls and components by their color. Use these knobs to control devices with round shafts and view settings at a glance with a pointer.

The small dial on these gauges allows for installation in tight spaces.

Read your pressure from a distance with these large-dial gauges.

Keep tabs on liquid levels in pump and tank applications with these gauges—a dual scale displays pressure in feet of H2O and psi.

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.

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.

These gauges have a unique case design that eliminates the air bubble on the dial face, which can distort readings.

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.

Gauges have an accuracy of ± 1% to ± 1.5%. They are suitable for critical processes that require high accuracy, such as hydraulic and laboratory applications.

Use these gauges to monitor the pressure of compressed gas.

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

Check the pressure on your drinking water system with these gauges—they meet NSF/ANSI Standard 61 for safe use with potable water.

Clearly read pressure levels in your drinking water system, even with heavy vibration. The dial face is filled with glycerin, which absorbs shock and keeps the needle steady.

Use in high-pressure applications up to 2,000 psi.

Designed for harsh environments prone to vibration, these gauges pair a corrosion-resistant 304 stainless steel case with a glycerin-filled dial to reduce needle flutter.

The case and connection threads are stainless steel for protection in corrosive environments.

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

Also known as compound gauges, these measure both pressure and vacuum.

A 304 stainless steel case coupled with 316 stainless steel connection threads provide protection from corrosive environments.

Measure small changes in air pressure with these gauges. They are commonly used to indicate clogged filters and to monitor fans and blowers.

These gauges have a glycerin-filled dial to reduce needle flutter for precise readings in high-vibration applications.

With an accuracy of ±0.25%, these gauges are designed for critical processes that require precision.

The 1/4 NPT male back connection fits smaller equipment than other threaded thermometers.

For installation in tight spaces, these thermometers have a side connection and face upright for easy viewing.

In addition to a pointer that shows the current temperature, these thermometers have a second pointer that indicates the highest or lowest temperature reached.

A thermowell covers the thermometer stem for protection from vibration, corrosion, shock, and pressure.

Monitor the temperature of corrosive fluids in harsh conditions.

Dry dials with acrylic lenses eliminate the risk of contamination in case of breakage, so these thermometers are often used in food-processing applications.

Monitor the temperature of difficult-to-access system components from a distance.

The included thermowell protects the probe from the effects of vibration, shock, pressure, and corrosive liquids in tanks and pipelines.

Attach these thermometers to the rims of tanks, trays, vats, and other containers.

For dairy, food, and beverage applications that require frequent cleaning, these 3-A certified thermometers have a sanitary quick-clamp connection for easy removal.

For use in food processing and preparation applications, these thermometers meet NSF/ANSI standards.

A removable rubber float keeps these thermometers on the surface of liquid-filled containers for hands-free temperature readings.

More precise than analog potentiometers, these have a three-digit display that is easy to read.
