Save the nitrogen in your hose reel for the next test
If you calibrate a high number of transmitters in a week, you definitely want to conserve your nitrogen. Especially when you're so far out in the field that going back to the shop isn't an option. Blowing off 100' of nitrogen in the test hose adds up over time.
With the addition of a few fittings, you can conserve the nitrogen in your hose between tests.
Note: The following diagrams show common examples of ways technicians kit out their hose reel to control nitrogen loss and perform calibrations. Not all items listed will necessarily fit your specific setup.
Info on the items listed in the diagrams
Regulator for your nitrogen bottle
XREG Pressure Regulator - Single stage pressure reducing regulator for use in providing a stable pressure to precision pressure control devices.

Test Manifold
QTCM - Fine adjust your test pressure right at the transmitter. Mount your calibration gauge to the top so you can see the readings as you fine-adjust.

Short (5 feet) Quick-test hose
QTQT-HOS-5ft - 5 feet of hose to connect your nitrogen regulator to the hose reel, the block and bleed valve to the test manifold, and the test manifold to the transmitter.

Fitting to tie-in to the transmitter manifold
QTF-4MBO - Easily connect a Quick-test hose to the transmitter for calibration. Easily sealed bubble-tight again when calibration is complete. Many pipeline organizations install the QTF-4MBO on all transmitter manifolds by default to speed up test setups and and post-test cleanup.
