About Hazardous Location Environmental Ratings

Rated for environments where hazardous material is present, these gauges measure the thickness of steel, stainless steel, and aluminum without removing the coating. They have an ultrasonic probe that provides highly accurate readings; use the included ultrasonic gel for maximum surface contact. Gauges come with a calibration certificate traceable to NIST that states the product has passed a test for accuracy. They include a steel test block for verifying the accuracy of readings.

Hazardous location environmental ratings indicate whether manufacturers have included safety features in products to facilitate their safe use in a hazardous environment. Before selecting a product for a hazardous location, ensure it is rated for your environment. See About Hazardous Location Environmental Ratings.

Gauges cannot be sold to California or Oregon due to electrical efficiency requirements.

Ultrasonic Thickness Gauges

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.
