Handheld Infrared Thermometers

Handheld Infrared Thermometers

Highly portable temperature sensing devices that use electromagnetic radiation to make non-contact surface temperature readings.

Humidity Meters / Hygrometers

Humidity Meters / Hygrometers

Measures the amount of water vapor in gases, most often air, in buildings, pipelines or as part of industrial processes to ensure the optimal amount of moisture is present.

Moisture Meters

Moisture Meters

Measures the percentage of water in solids, gases and hydrocarbon liquids through a variety of invasive or non-invasive technologies.

Air Velocity Meters / Anemometers

Air Velocity Meters / Anemometers

Used to measure the speed and/or volume of air movement. Commonly found in weather stations as well as applications such as the analysis of ventilation systems, aerodynamics testing, and fume hood verification.

Sound Level Meters

Sound Level Meters

Quantifies the intensity of sound waves to ensure sound levels are within acceptable ranges as regulated by occupational health agencies, the Environmental Protection Agency, state laws and local ordinances.

Light Meters

Light Meters

Precise instruments designed to quantify the amount of light, both natural and artificial, to ensure optimal levels of lighting to reduce the energy burden of buildings while fulfilling compliance with OSHA regulations.

Multimeters

Multimeters

Electrical testers that combine several measurement functions into one unit making it an essential instrument for testing or troubleshooting electrical problems in a wide array of industrial and household devices.

Clamp Meters

Clamp Meters

Non-contact current measurements using wide jaws which clamp around the outside of an electrical conductor. Usually also includes measurements for voltage, resistance, continuity, capacitance and others.
