I see on the adapter search page Commercial and MIL-Grade but what about laboratory and metrology grade? Is there a way to narrow the search parameters for these types? Does ECM carry these types? Some indicators of quality I don't see how to focus on are IEEE std. 287, metrology grade, LPC, and slotless (PSC). I'm a little disappointed I don't see some of the high end adapters from Keysight Technologies but then maybe their supply is in the list of manufactures you work with. I know Amphenol and Maury make some stuff for Keysight. I don't know who does the Keysight PSC connectors.

from Southwest Microwave:   

In short, we may meet the tolerances for the metrology grade, but our tolerances on the drawing are wider than metrology grade. As our adapters are performing very well, we promote them as precision adapters, for a much lower price than the metrology grade ones.Secondly, we are also supplying a lot of products to Keysight, they are our number 1 customer. We do a lot of switch connectors for them and we are currently designing new ones, up to 67 GHz and 110 GHz.

from Maury Microwave:

No, the products that you have listed on your website from us are not metrology grade. The ColorConnect are precision grade and the Test Essentials are lab grade. The "slotless" connector that the customer mentions below is a patented design that is used by Keysight. We have access to the patent and they actually supply us parts so we can build these into items we produce for them.

 

However, while the slotless (or "Botka" connector, because it was designed by Dr. Julius Botka) has extremely low VSWR, it is very fragile and can far too easily be destroyed by a single mating. Our metrology adapters use a traditional slotted contact because we feel that it offers better performance over the acceptable life of the connector.

 

It is incorrect to say that only slotless connectors are metrology, although Keysight might argue this point in a technical sales discussion.

What is being sighted below is an IEEE standard for slotless connectors, which are identified as metrology, but the term metrology is not restricted only to the slotless design.
