Overview
The Defelsko STDB1 calibrate block is a tool for inspecting Ultrasonic Thickness Gauge calibrates and operations, and is an essential part of meeting ISO and internal quality control requirements. The product is made of 1018 steel and is available in metric and imperial units and comes with a calibrate certificate dating back to NIST/NPL.
Features
The material is 1018 steel, which is sturdy and durable.
2. Available in metric and imperial unit sizes.
3. Metric specifications include 2.5, 5, 7.5, 10 and 12.5 mm steps with an accuracy of +/- 0.02mm.
The imperial specifications include 100, 200, 300, 400 and 500 mil steps with an accuracy of +/- 1 mil.
5. A calibrated certificate traceable to NIST/NPL is provided with the product.
Principle
This product is used as a standard reference block for known Film thickness. Film thickness is measured by Ultrasonic Thickness Gauge, and the measurement result is compared with the standard value of the calibrated block to verify the measurement accuracy and calibrated state of the thickness gauge.
Applications
Ultrasonic Thickness Gauge calibrating, industrial quality control, equipment maintenance testing
Steps
1. According to the measurement needs, choose metric or imperial calibrated blocks.
2. Use Ultrasonic Thickness Gauge probe, according to the instrument operating specifications, measurement calibrated block is not synchronized long (such as 2.5mm, 5mm, etc.) Film thickness.
3. Compare the measurement reading of the thickness gauge with the standard value of the corresponding step on the calibrated block.
4. According to the comparison results, judge the measurement accuracy of the thickness gauge, and calibrate or adjust according to the calibrating certificate if necessary.
Notice
• Before use, please confirm that the unit system (metric/imperial) of the selected calibrated block is consistent with the thickness gauge settings.
• Follow the specifications for the use of Ultrasonic Thickness Gauges and calibrated blocks when operating.
• Please keep the attached calibrated certificate safe for inspection.
• Avoid hitting or scratching the calibrating block to prevent its accuracy from being impaired.
• The calibrated block is a precision tool and is recommended to be stored and used in a suitable environment.
