These angle indicators come with a calibration certificate that's traceable to NIST and includes the test measurements that confirm accuracy.

Align guide rails or lay pipe at specific angles from a flat surface.

The pad below the base absorbs shock and vibration.

Direct your signal with these lights; they flash in one direction.

Place these lights in full sun and their batteries charge during daylight hours. Lights automatically switch on at dusk and off at dawn.

Small as hockey pucks, these lightweight strobe lights mount to surfaces and are unobtrusive when they’re turned off.

These lights have lenses that snap in and out, so you can easily swap colors or change their position in the stack.

Mount these lights horizontally or vertically in places where a tower will not fit.

These lights emit three colors from a single lens and can be mounted in tight spaces where a tower will not fit.

Give a signal with the push of a button. These lights have a control box for activating each of the three light modules.

Good for tight spaces where a tower of lights won't fit, these emit three colors from a single lens.

Sirens can emit both continuous and pulse tones—pulse tones alternate on/off to draw greater attention than continuous tones.

Buzzers are UL listed for use in environments where flammable gases, combustible dust, and combustible fibers may be present.

Buzzers meet NEMA 4X for protection and corrosion resistance in washdown environments.

Horns are UL and C-UL listed for indoor and outdoor use in Class I, Division 2, Groups A, B, C, and D; Class II, Division 2, Groups F and G; and Class III, Division 2 hazardous locations.

The quick-opening valve on these whistles allows manual operation—pull the valve while air or steam pressure is being applied to produce a shrill tone and alert workers.

These make great doorbells when used with a push button.

Monitor hydraulic fluid or oil level in pressurized applications.

These flexible indicators bend to follow the contours of a tank.

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

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

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

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

These sights have a glass window.

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.

Easier to read than U-tube gauges, these use an inclined scale to measure pressure or velocity changes in air applications. They are also known as manometers.

Place these indicators anywhere you need to detect and warn about the presence of carbon monoxide. The circle in the center darkens when carbon monoxide is detected and returns to its normal color when exposed to fresh air.

Continuously measure ambient sound levels. The display alerts you when levels either exceed or fall below your programmed thresholds.

In addition to an audible signal, these alarms flash a high-intensity strobe to draw attention during fire emergencies.

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.

A rubber coating or construction provides a comfortable grip. Use these knobs to control devices with round or D-shaped shafts and view settings at a glance with a pointer.

Slot these counters into a control or electrical panel cutout.

For quick installation, these counters fit into standard DIN panel cutouts.

The digits displayed on these counters are visible up to 100 ft. away.

Count metallic objects as they touch or pass within 0.059" of the built-in sensor.

These scoreboards automatically count days.

This horn has a built-in compressor, similar to that in a car horn, for a louder sound than other lift truck horns.

These horns produce a sound loud enough to be heard in industrial settings.

Indicate forward or reverse motion with these bells. They mount directly to a vehicle's wheel hub, without switches or wires.
