Pressure range (psig)
-14.69 to 608.22
Temperature range (°F)
-259 to 200
Note: PT points are stored in psig and °F. For blends, bubble and dew represent different saturation states. Always follow OEM charging procedures.

Quick actions

These routes are designed to be technician-friendly: minimal taps, prefilled context, and predictable URLs for bookmarks and sharing.
