January 12, 2016
Q: Is this price for the instrument only? Do I have to buy the CHT and EGT probes separate?
Yes, this is the price for the instrument only. You will have to order the EGT and CHT probes separate. You can go to the Aircraft Spruce search box and type Westach to see a listing of the different types of probes we sell for this gauge.
Q: Do these Westach Dual EGT CHT instruments have a TSO or PMA? Or are they for experimental only?
No, this instrument is not FAA Approved. It is intended for use in experimental aircraft only.
