Reed Instruments TM-8811-NIST Ultrasonic Thickness Gauge with NIST Traceable Certificate

The REED Ultrasonic Thickness Gauge measures the thickness of steel, cast iron, aluminum, red copper, zinc, quartz glass, polyethylene, PVC, gray cast iron and nodular cast iron. The exclusive micro-computer LSI circuit and crystal time base offer high accuracy and the digital display provides exact readings with-out guessing or errors. The meter features a display sound velocity at the touch of a button, broad band receiving sensitivity (which means the meter can read probes of different frequencies) and automatic material calibration.
