Description
Elcometer 204 Steel Ultrasonic Material Thickness Gauge
Pre-calibrated for ease of use, the new Elcometer 204 steel ultrasonic thickness gauge provides fast, accurate measurement of the thickness of steel.
In addition to the material thickness measurement, the new Elcometer 204 displays key statistical values required to assess the overall material thickness; number of readings (n), the average material thickness (x), the lowest (Lo) and highest (Hi) material thickness, the standard deviation (σ) and the coefficient of variation (CV%).
Zero Point calibration for accuracy
The new, easy to use, Elcometer 204 has zero point calibration, ensuring accurate thickness measurements on steel surfaces.
As each measurement is taken, the new Elcometer 204 transmits the thickness values via USB straight into an inspection application or into ElcoMaster®, for instant report generation.
Key features of the Elcometer 204 Steel Ultrasonic Material Thickness Gauge include:
- Pre-calibrated for measuring on steel only
- Measures steel thickness from 0.63mm up to 500mm (0.025 – 20”)
- Pre-set measurement rate of 4Hz (4 readings per second) provides faster readings
- Supplied with everything required for use
- Measures the material thickness when there is access to only one side
- Integrated zero disc, ensures maximum accuracy
- Transfer live readings via USB to ElcoMaster®
- Intelligent transducer attached with auto recognition, ensures correct probe is identified when transducer is changed. The Elcometer 204 is supplied with a 5MHz ¼” Potted Right Angle Dual Element Thickness Transducer.
