    • QC is lacking. No excuse for shipping the tool when parts were missing!
Item was shipped missing the probe. Tool was needed for a job and now has to be reordered. Costly delay of job.

Well made! Expensive, but worth it. Tuning an oil-fired boiler is a dream with this device.

    • Warranty
Meter worked great the first heating season. Going into the second season the meter would not level back down to zero in fresh air. Fieldpiece won’t honor warranty because this was purchased through Amazon and not a Fieldpiece dealer.
