    Ultrasonic Thickness Gauges

    Image of Product. Front orientation. Thickness Gauges. Ultrasonic Thickness Gauges.
    Measure the thickness of material such as metal and plastic. The ultrasonic probe provides highly accurate readings. These gauges come with a calibration certificate traceable to NIST that states they have passed a test for accuracy. They also include a USB cord for connecting to your PC. Use the included ultrasonic gel for maximum surface contact.

    Ultrasonic Portable Hardness Testers

    Image of Product. Front orientation. Hardness Testers. Ultrasonic Portable Hardness Testers.
    Using ultrasonic vibrations, these testers determine hardness without leaving an indent on hardened materials. They only leave minimal damage on softer metal and work on metal as thin as 0.08”. Use the included test block to determine the right amount of force to apply to your probe. To perform a test, press the diamond tip probe into your material and apply consistent pressure for reliable results. These testers are highly precise and convert measurements between Rockwell, Vickers, and Brinell ratings. Measurements are shown on a backlit digital display, so you can read them even in dark or dimly lit areas. Store up to 2,000 readings with their built-in memory or transfer the data to your PC using the USB port. Small enough to carry, take these testers to your material. Their lithium ion (Li-Ion) battery keeps them running for up to six hours before recharging is required.
    NIST calibrated test blocks are included to help you understand how to properly press the probe to your material for an accurate result. The test blocks can also be used to recalibrate the device. These testers must be calibrated to the specific hardness scale and material being tested. They come pre-calibrated with five combinations: aluminum on the Rockwell B scale, brass on the Rockwell B scale, steel on the Rockwell C and B scales, and steel on the Brinell scale.

    LCD Display

    This detector converts ultrasonic waves to an audible sound so you can find leaks. Unlike typical leak detectors, this unit doesn’t rely only on the presence of a gas to work, making it suitable for a wider range of applications. In addition to gas leaks, it identifies ultrasonic sound caused by failing solenoids, valves, and bearings.

    Remote-Reading

    Premium Compact

    Check the tension of your machine’s flat, timing, or V-belt—no matter its width. These gauges use ultrasonic sound waves to take noncontact readings. To measure, simply pluck the belt like a guitar string to create vibration. Because they don't touch the belt, they won't accidentally change the tension like a traditional gauge might.
    For gauges without a keypad, you’ll need to manually calculate your belt’s rating in pounds or newtons using its hertz rating, weight, and length.
    Economy—Economy gauges are often used to test standard rubber belts in light duty machinery and automotive engines.
    Premium—Premium gauges are specifically engineered for heavy machinery. Their software and sensors are fine-tuned to accurately measure high-performance belts, such as those made of carbon fiber or Kevlar.
    Remote Reading—Remote-reading gauges have a sensor attached to a cable to measure in hard-to-reach spots.
    Dual Sensor—Gauges with a dual sensor give you two ways to measure. For one-handed use, measure with the sensor built into the display instead of the cable sensor.
    Keypad—Gauges with a keypad convert the hertz rating into pounds or newtons when you input your belt’s weight and length.

    Distance-Measuring Modules for Development Boards

    Stream distance readings to your development board in real time. Set up these modules near your robotics, production lines, or liquid monitoring systems to capture changing positioning.
    Ultrasonic Modules

    Ultrasonic modules use sound pulses to measure distance. They can be used in low lighting. However, they may not be accurate on soft, small, or oddly shaped objects that won’t reflect sound waves properly.

    Acoustic Imaging Gas Leak Detectors

    Image of Product. Front orientation. ZoomedIn view. Contains Inset, Border. Gas Leak Detectors. Acoustic Imaging Gas Leak Detectors.
    Locate leaks up to 10 times faster than traditional leak-detecting methods. These detectors use 124 microphones to determine the precise location and size of leaks in compressed air and specific gas systems. The screen displays a high-resolution acoustic image that’s overlaid on a digital live shot of your facility to help you visualize the leak. It also displays analytics related to the leak, such as the rate and the potential cost savings of patching your system. You can capture the on-screen view through photos and video to review later. With a built-in flashlight, they remain accurate even in low-light spaces. Light enough to carry with one hand, you can bring these detectors on the go. A 650 ft. range means you can use them from one end of your facility to another, or to detect in hard-to-reach systems.
    Connect the detector to your computer using Wi-Fi or the included USB cable to quickly transfer collected data.
