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.
Do you check the accuracy of your weighing scales on a regular basis?
The Washington State Department of Agriculture will preform unannounced inspections on all industrial scales used for commercial use. Scales are subject to stringent requirements and rigorous testing before being approved for a COC.
Be prepared and stay ahead of the game. Have your scales calibrated by a service company or agent that is registered with the State of Agriculture, this this will ensure accurate measurement and prevent device malfunction. The service agent will provide you with a calibration certification that states it is in accordance to the specific requirements for WA State.
Your Basic Responsibilities
As an owner or operator of weighing or measuring equipment you are responsible for the maintenance and accuracy of your devices at all times. This includes but is not limited to assuring that:
- The device is suitable for its intended use (by design, capacity, etc).
- The device has an NTEP Certificate of Conformance.
- The device is installed according to the manufacturer’s instructions.
- All operating requirements are met such as indicating element visible, users are properly trained, and all transactions begin from a “zero” basis.
- Suspected device errors or out-of-adjustment conditions are promptly checked and repaired by a registered service agent.
- Security seals are properly installed on the device adjusting mechanism.
- Devices are correctly registered with the Department of Revenue, Business Licensing Service.

Do you know if your torque wrench is out of tolerance?
Mechanical and electronic torque wrenches require regular calibration because the internal mechanisms can wear, fatigue or become jolted out of accuracy by a drop or misuse.
CDI, a In Snap-on Industrial Brands has created the New DTC Digital Torque Checker. This new technology offers quick, accurate and affordable way to check your torque wrenches as easy as 1-2-3, taking only a few minutes. Simply mount torque checker close to each department where torque wrenches are used,attach the torque wrench to the checker and the accuracy will be displayed on the digital screen.
Features of this new digital torque checker:
- +- 1% Accuracy
- 1/2″ dr. 25-250 ft.lbs.
- Runs on 3 “AA” batteries
- Includes 3/8″ adapter
- Features excerciser socket
- Adjustable sleep timer
- Track peak and first peak torque force.
The video below will show you the benefits and how to use the Snap-on torque checker which is the same as the CDI Snap-on Industrial brands DTC torque checker.
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.
