It is great to be able to afford a CHT gauge that is compensated for ambient temperature. Thank you for carrying it! Van Baehr

Initial installation instrument read 200 degrees in 60 degree hangar. Almost any heat applied to probe would send it off scale to high side. Returned instrument for evaluation. Two months later received instrument that seems to work. No idea if the replaced instrument or repaired the one we sent in.

Q: Do I have to order the probes separately for the Micro 1000 CHT?

You must order the probes for the micro 1000 CHT separately. They come in 10, 12, 14, and 18mm.

Q: Other than than mounting design, are there any mechanical of functional differences between the 2 1/4 square mount and the 2 inch round gauges?

No, only the size and mounting design are different.

Q: Does the 2-1/4 square gage have a round bezel with a square mount that can be mounted into a round 2-1/4 hole?

The 2-1/4" gauge is a standard 2-1/4" round bezel with the 2-5/16" square plate for mount in a round hole.

Q: It is well indicated that the CHT guage Micro 1000 does not come with the cylinder probe, but does it come with a the lead between the guage and the probe?

No, it does not come with the lead. You will need to purchase that separately. 10-01442 is a 7ft lead and 10-01443 is the 15 ft lead.

Q: Does the Micro 1000 need 12 volts to operate? Will it work properly in an aircraft without an electrical system?

It will work fine in an aircraft without an electrical system.
