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. Energy efficiency requirements restrict sales to the listed areas.

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.

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 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.

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.

Economy gauges are often used to test standard rubber belts in light duty machinery and automotive engines. 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 gauges have a sensor attached to a cable to measure in hard-to-reach spots. 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.

Gauges with a keypad convert the hertz rating into pounds or newtons when you input your belt’s weight and length. 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.

Measure the thickness of material such as metal and plastic. The ultrasonic probe provides highly accurate readings. This gauge comes with a calibration certificate traceable to NIST that states it has passed a test for accuracy. It also includes a USB cord for connecting to your PC. Use the included ultrasonic gel for maximum surface contact.

Use calibration blocks to calibrate your thickness gauge. All blocks have a serial number and come with a calibration certificate traceable to NIST.
