Measuring and Inspecting

Gas Leak Detectors

Gas Leak Detectors

Find gas leaks in pipes, tubes, fittings, tanks, cylinders, and valves

Leak-Detecting Dyes

Leak-Detecting Dyes

Bright colors help you spot leaks in water and hydraulic systems without using ultraviolet light

Leak-Detecting Pipe Flange Covers

Leak-Detecting Pipe Flange Covers

Wrap around pipe flanges to show when there's a leak and contain it

Smoke Pens

Produce smoke to observe airflow and detect leaks in HVAC systems; reusable, unlike smoke candles

Fog Machines

Produce a continuous fog to observe airflow and detect leaks in HVAC systems

Radiation Detectors

Radiation Detectors

Test for radiation, even in low amounts or from microwave ovens

Smoke Candles

Light the wick for a short burst of smoke to observe airflow and detect leaks in HVAC systems

Smoke Pellets

Detect airflow and leaks in HVAC systems near server rooms and other areas with electronics

Smoke Powder

No flame needed—release a burst of powder to detect airflow and leaks in HVAC systems

Ultraviolet Inspection Lights

Ultraviolet Inspection Lights

Shine on equipment to detect traces left behind by leaks, rodents, and other contaminants

Monoculars

Magnify still objects from far away to view features you couldn't see with the naked eye

Vibration Meters

Vibration Meters

Spot-check vibration to gauge the health of your machine

Thermal Cameras

Thermal Cameras

Detect hot spots, leaks, moisture problems, and construction defects invisible to the eye

Combustion Analyzers

Combustion Analyzers

Measure boiler and furnace combustion efficiency

Stethoscopes

Detect internal mechanical problems like worn parts, excessive vibration, and fluid leaks

Safety Equipment

Multi-Gas Detectors

Multi-Gas Detectors

Monitor air for carbon monoxide and combustible gases including methane, hydrogen, and propane

Carbon Monoxide Detectors

Carbon Monoxide Detectors

Alarms, lights, or color changes alert you to the presence of carbon monoxide

Oxygen Detectors

Oxygen Detectors

Too much or too little oxygen triggers alarms and warning lights

Carbon Dioxide Meters

Pigments and Dyes

Add color to liquids, mixtures, and materials

Fluid Handling

Water Detector Sensors

Water Detector Sensors

Place near tanks, sump pumps, and pipe lines to alert you to water leaks

Test Pumps

Force air or liquid through your system to look for leaks; often called hydrostatic test pumps

Electrical

Development Board Sensor Modules

Development Board Sensor Modules

Transform your development board into everything from an airflow monitor to a motion detector

Communication

Audible Alarms

Everything from bells and whistles to horns and sirens
