About Relative Visibility of Signal Lights

Heavy Duty Magnetic-Mount Angle Indicators

These angle indicators have a horizontal leveling vial and can measure angles between 0° and 180°.

Magnetic-Mount Angle Indicators

Temporarily mount these indicators to a metal surface. They have four quadrants that each read any angle from 0° to 90°.

Pocket Digital Angle Indicators

At 2 1/4" square and 1" wide, this angle indicator easily fits into your pocket.

Pocket Digital Angle Indicators with Level

These angle indicators also show level on the display.

Digital Angle Indicators with Laser

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

Digital Protractors with Level and Laser

A dot laser extends the working distance 200 feet beyond the tool length. This tool has two digital displays that invert when turned upside down; one shows the base angle and the other shows the moveable arm angle.

Vibration-Monitoring Kits

Keep machinery running smoothly by monitoring its health and status from your computer. Often used with electric motors, pumps, and lathes, these kits measure changes in vibration, and temperature—identifying equipment problems and potential failures before they occur.

Magnetic Digital Levels

These levels have a plastic housing.

Magnetic Post Levels

A magnet keeps this 90° level in place while you position posts and corners.

Control of Liquids, Gases, and Solids

Low-Pressure Differential Gauges with U-Tube

Also known as manometers, these gauges come with indicating liquid that moves up and down two columns—the difference in height between them is your pressure.

Air Sensors for Differential Pressure

Use these sensors with differential pressure gauges and switches to measure the static pressure drop across air filters, cooling coils, and blowers in air-handling equipment.

Remote-Reading Magnetic-Back Thermometers

Remotely check temperature on the go. These thermometers have a magnetic-back display for temporary mounting and a thermocouple probe with a 5-ft. coiled cable.

Minimum/Maximum Indicating Magnetic-Back
Surface-Temperature Thermometers

In addition to showing current surface temperature, these thermometers have pointers to indicate the minimum and maximum temperatures since the last reading.

Remote-Reading Magnetic-Back
Thermometers with Calibration Certificate

Externally monitor the air temperature inside freezers, refrigerators, water baths, and incubators. These thermometers come with a calibration certificate traceable to NIST that states they’ve passed a test for accuracy.

Magnetic-Back Surface-Temperature Thermometers

Check the surface temperature of tanks, generators, annealing ovens, boilers, and other metallic equipment.

Quick-Connect Thermocouple Probes for Surfaces

The probe tips come attached to mounting connections for fast installation.

Signal Lights

Pocket-Size Continuous/Flashing Lights

Carry these lights around with you and place them wherever needed. They can switch between being continuous or flashing.

Continuous/Flashing/Revolving Lights

These lights can switch between continuous, flashing, or revolving.

Battery-Operated Flashing Lights

Quickly position these portable flashing lights using the magnetic base to draw attention to hazards in areas such as docks and railroad crossings. They are battery operated, so they do not need to be wired or plugged in.

Solar-Powered Flashing Lights

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

Flashing Lights with Vehicle Plug

Flashing Light Bars with Vehicle Plug

These lights cycle through three different flashing patterns.

Multiple-Flash Strobe Lights with Two-Prong Plug

These strobe lights flash multiple times per cycle, making them easier to spot than standard strobe lights.

Compact Strobe Lights with Vehicle Plug

As small as a hockey puck and compatible with standard 12-volt vehicle plugs, these strobe lights are inconspicuous when not in use and quick to connect.

Low-Profile Dome Strobe Lights with Vehicle Plug

Multiple-Flash Strobe Lights with Vehicle Plug

Easier to spot than other strobe lights, these lights emit bursts of five flashes per cycle.

Narrow-Dome Strobe Lights with Vehicle Plug

Strobe Light Bars with Vehicle Plug

A series of four flashes per cycle makes these lights more visible than other strobe lights.
