Optical Comparators are inspection machines that project magnified images of parts onto a glass screen using illumination sources, lenses and mirrors for the primary purpose of making 2-D measurements.
Using an Optical Comparator allows the technician to see the part from the magnified form up to 50 times the actual size.
Very small radii and other featured can be easily checked when enlarged on the screen. Including thread gages, thread standards and specialized tooling.
This saves time, money and will ensure your gages meet specific federal guidelines.
RPTS meets the need for higher accuracy and more frequent calibration of thread plug and thread ring gages.
Thread plug and thread ring gages are used to check measurement of pitch and diameter of threaded items. Many companies are seeing costly mistakes and product recall due to these gages giving an incorrect measurement. To prevent these mistakes companies are requiring frequent calibration at higher accuracy to ensure the product delivered to the customer is an efficient and accurate tool.
RPTS recommends thread plug, thread ring gages and any precision instruments be calibrated by an accredited calibration laboratory with long form certification traceable to N.I.S.T. (National Institute and Technology) to ensure all gages meet the required industry standard. It is critical that these gages are calibrated on a regular cycle. This cycle depends on the amount of use and if the thread plug and thread ring gages that have been dropped or impacted. RPTS suggests an annual calibration, setting a date every year to have your gages calibrated.
Robb Precision Tool Services is an A2LA Accredited Calibration Laboratory that follows ANSI/ISO/IEC17025:2000 and will provide a long form calibration certificate traceable to N.I.S.T. standards for all thread plug and thread ring. A long form certificate lists in detail all of the characteristics needed to ensure conformance. All thread plug and thread ring gages are calibrated by a trained technician in temperature controlled laboratory.
