INFICON Pilot® Plus is the only HVAC/R service gauge that uses a Pirani sensor to measure the entire evacuation process — from atmosphere right down to 1 micron. The G27 KF-16 version mates to KF vacuum hardware; add an adapter for 1/4″ SAE when needed. It’s dead-simple to read, filter-protected, and runs up to 45 hours on a single 9 V. Fair dinkum, this thing saves time on every pull-down.
Key Features & Trade Benefits
- Pirani sensor, full-range (atm to 1 micron) — see the whole evacuation curve, spot leaks fast, and finish with confidence. Fewer call-backs.
- Industry-first filter on the sensor — protects against oil/contaminants for more stable readings and less cleaning. More time on the tools, less maintenance.
- Quick calibration to local pressure — one-button ambient cal so your numbers stay honest from Perth to Cairns.
- Extended battery life (≈45 h) + auto shut-off — work multiple jobs on one battery; resumes with last reading. Too easy.
- Big, clear LCD + multi-units — display in microns, Pa, mbar or Torr to match your documentation.
- KF-16 connection (G27) — rock-solid vacuum interface; add a KF-16→1/4″ SAE adapter for common hose sets.
Why This Product Matters
Up on a Brisbane roof at 3 pm, you’ve hit 500 microns but the rate-of-rise creeps — is it moisture or a fitting? Pilot Plus shows the full pull-down and recovery so you can isolate, re-tighten and verify without guesswork. It’s a bloody good way to keep handover on schedule. If you’re comparing gauges, check our Vacuum Gauges for more options.
Pro Tip
Ambient-cal the gauge at the vehicle before you hook up. Use core removal tools and large-ID evacuation hoses direct to the pump; then perform a rate-of-rise check with the Iso-valve on your pump or service valves shut. She’ll be right when the micron curve holds flat.
Compatibility & System Info
- Connection: KF-16 flange (model 710-202-G27). Use a KF-16 → 1/4″ SAE female-flare adapter when connecting to standard HVAC hoses/manifolds.
- Measurement range: Atmosphere (≈760,000 microns) down to 1 micron.
- Display units: microns, Pascal, millibar, Torr.
Local Jobsite Note (AU)
Humid summer conditions in Sydney can slow dehydration. Use the filter-protected Pilot Plus with a fresh pump oil change and big hoses to keep moisture moving — no dramas.

FAQs
Yes — add a KF-16 → 1/4″ SAE FFL adapter and you’re good to go.
The Pirani sensor and built-in filter give stable, repeatable low-micron readings across the full range; quick ambient cal helps account for local pressure. Always verify with good hoses and a rate-of-rise test.
G1 has a 1/4″ refrigerant flare fitting; G27 is KF-16. Pick based on the interface you use most — adapters available either way.
