Q & A

Questions You May Encounter on the 721Ex

Question: The 721Ex looks complicated. Isn’t it easier to just use a simple pressure gauge?
Answer: The 721Ex has a streamlined user friendly user interface. Easy to use right off the quick reference card, no need to read the manual.

Question: I’m used to using the Crystal IS-33, is the 721Ex as reliable?
Answer: The 721Ex is based on proven Fluke technology and features a 3-year warranty standard vs 1 year on the IS-33. It’s also important to remember that the 721Ex also measures temperature

Question: I’m not familiar with Fluke pressure calibrators, have they made them long?
Answer: Fluke has been making portable pressure calibrators for over 20 years. The 721Ex benefits from proven designs and state-of-the-art pressure measurement technology

Question: What is different between the 721 and the 721Ex besides being red and Ex rated?
Answer:To achieve the Ex rating is was required to remove 24 v loop power, voltage measure and connectivity to Fluke-750P series pressure modules. The 721Ex has a slightly narrower operating temperature range (45 C max vs 50 C max on the standard 721).

Questions you may encounter about pressure accessories:

Question: How do these pressure accessories make pressure calibration easier?
Answer: These premium accessories mean that No Tools Required to make pressure calibration test connections. This saves time and money for pressure maintenance activities.

Question: How to these accessories seal pressure connections without tools? Why is PFTE tape not needed?
Answer: These pressure accessories have a unique flush facing seal that seals to the flat surface on the input of most process devices and calibrators. 

Question: Once I get these accessories installed how do I use them best?
Answer: Once the kits are assembled, you permanently connect one end to either the hand pump or pressure calibrator. There is an easy NTR connection on the hose to easily connect and disconnect. On the other end of the hose kit is a flush facing seal designed to connect to most transmitter with IEC industry standard connections. There are also special kits for metric and Chinese M20 connections.

Question: What is the pressure ratings of the pump kits? 
Answer: There are two versions of the Transmitter Test Hose, 5,000 psi and a 10,000 psi rating. Also there are two different pressure ranges for the pump kits. The 700PTPK2 is rated to 600 psi and the 700HTPK2 is rated to 10K psi. 

Question: What is included in the pump kits?
Answer: The PTPK2 and HTPK2 include the hard case, pump, NTR transmitter test hose, Teflon tape (for initial assembly) and a special NTR connection for connecting and disconnecting 700G test gauges or other ¼” NPT male connections.
