EIS 9000 Package for 9-
The current Model 9000 instrument is now available as a package (see EIS price list). Please note that at this time, it can only monitor 12 total CHT/EGT inputs. We recommend monitoring 9 EGT and 3 CHT. A rotary switch can be used to select different cylinders to view their CHT readings.
The EIS 9000 package comes with 3 CHT probes. Additional CHT probes are available for $18 each.
A new version of the EIS that monitors all 9 EGTs and CHTs is currently in development. The current model 9000 will be upgradeable to the new version.
