Where is the best and least expensive place to get a replacement O2 sensor (#0390 0047) for my Testo 327-1. Last one I bought was in 2021 and it was $100. Everything I can find now is $210

    Its been 4 years. It may be best to send it back to testo to have them give it a once over.

    If you buy one instead of sending the tool in for calibration I would want a calibration date for the sensor before purchasing, they have a shelf life which is why you typically do not see them hanging out at supply houses etc. When I asked my manufacturer if they thought I should stock them they told me absolutely not and they wanted the extra my customer didn't need returned at no charge so they didn't sit around waiting for a sale.
