Q
Is air gauge head compatible with every air micrometer of different maker?
ABasically, each air gauge head is designed and manufactured following the specification required by air micrometer used. Particularly, for air micrometer with back pressure type (digital type), each maker has its own specification upon its air gauge head. And hence, basically, there is no compatibility guaranteed between gauge head and air micrometer of different maker
For flow type air micrometer (analog type), its air gauge head almost has the same specification, regardless the maker.
It should be noted also that air gauge head designed for back pressure type does not always work well on the flow type.

Q
Is there any appropriate storage method of gauges?
AYou should pay attention to the following when storing the gauges.
• Do not store the gauge assembled into the product or other gauge.
• Remove it before storing.
• Wipe off dust, debris or fingerprints stuck on the gauge.
• The storage room needs stable temperature and low humidity.
• Clean the gauges with anti-rust oil to prevent rust.
• Before transportation, our gauges are covered with anti-corrosion packaging materials and moisture-proof plastics during the packaging process. Sealant is beneficial to the protection and anti-corrosion of the gauges. Moreover, this moisture-proof plastic is a rust-proof vinyl, which also prevents corrosion.

តើអ្នកផ្តល់សេវាកម្មសម្រាប់ដំឡើងទេ?
AYes.We also have an installation team abroad.Firstly,installation drawings will be given before the goods arrive at the destination port.If you need,we can arrange engineers to do the instruction on the project site.For big project and customers’ requirements,we can provide a whole project team.
・Do not store the gauge assembled into the product or other gauge.
・Remove it before storing.
・Remove any dust, chips, or fingerprint sticking on the gauge
・Store at room with stable temperature with low humidity
・Clean the gauges using anti-corrosion oil to prevent from rusty.
Most of our gauges are covered using anti-corrosive packing material (Seal Peel) and zerust plastic when shipping. Seal Peel can be used for guarding the gauges and corrosive prevention. Furthermore, zerust plastic is an anti-rasting vinyl which also can prevent from corrosion.

Q
Ten questions to ask when buying ring gauges
ATo determine whether the ring gauges you're considering will best meet your requirements, you need to ask the right questions.
While the quality of cylindrical ring can vary depending on the manufacturer, customers often treat these gauges as commodity items. As a result, the primary question that customers ask is, "What is your price and delivery?" In reality, that should be the last question asked. Here are several questions you should pose first, to ensure that the gauges you purchase truly meet your company's requirements and industry standards.
TWhat material is used to manufacture the ring gauges?
It is important that the ring-gauge material be stable and hard. Good-quality tool steels such as 8620 or O6 are appropriate choices. Steel blanks should be heat treated to a minimum of 62 Rc.
Do you inspect incoming material for adherence to hardening specifications?
The material is the foundation of ring-gauge quality, so the answer should be an emphatic "yes."
After heat treating, do you stabilize the material?
While heat treating helps stabilize steel blanks, subsequent grinding operations can affect the material by introducing heat and stress. A quality-conscious gauge manufacturer will eliminate material fluctuations entirely by putting blanks through a stabilization process, which involves cycling the rings through temperature extremes from -130 F to 300 F. Further, flange-type rings should be stabilized again after grinding.
Are your gauges precision lapped by hand?
Lapping is the process in which minute amounts of material are removed to bring the ring to final size and within tolerances. It is the final process in ring manufacturing, and extremely critical. It requires a highly skilled person who has learned to "feel" a millionth of an inch. No automatic lapping machine comes as close in accuracy and precision as a person who has mastered the art. Unskilled lapping can result in rings with excessive out-of-round or tapered conditions.
Do you inspect your gauges in a temperature-controlled metrology laboratory?
Although rings are inspected for size and class in a temperature-controlled lapping room, it is important that final inspection occur in a separate, environmentally controlled metrology laboratory.
What is the sampling of the gauges you inspect?
To ensure the utmost integrity, every ring should be inspected before it is shipped to the customer.
Will you certify my ring gauges?
This is becoming more important as International Organization for Standardization (IS 0), Geneva, Switzerland, and other quality-improvement programs demand gauge calibration and tracking documentation. Make sure your ring-gauge manufacturer has documentation systems in place to certify, track, store, and update gauge information.
Do you certify both class and size?
Both types of certifications detail the standards followed and include NIST-traceability statements for the laboratory. A Certification of Class simply states that the ring has been inspected and found to be within the tolerance band of the class that is marked on the ring. A Certification of Size provides actual size deviations from nominal for calibration points in two axes and three planes for each axis, for a total of six readings.
Does the certification contain a Statement of Uncertainty?
A properly prepared certification should also contain a Statement of Uncertainty for the readings given.
What is your price and delivery?
Only at this point, when you've received answers to the previous nine questions, is it an appropriate time to ask this final question.
