Stratomaster Maxi Single 

 

ALT-3, ALT-4, ALT-5 

 

ALT-3: Wide range precision aviation altimeter 
ALT-4: Encoding altimeter with Gillman code transponder output  
ALT-5: Encoding altimeter with serial output, compatible with 
IIMorrow, Garmin/Trimble or MGL RS232 protocols. 

 
 

 

 
The ALT-3 altimeter is a 3.5” instrument that can be used as absolute or relative altimeter. 
In addition, it offers a wide range VSI (vertical speed) indicator as standard option. 
 
ALT-4 and ALT-5 models include a gillman code and serial transponder interface. 
 
The altimeter conforms to ANSI standard atmosphere rules from –700 ft up to a minimum of 
40.000 ft. Accuracy is ensured by thermal compensation of the laser trimmed pressure sensor. 
High resolution is made possible by stable and sensitive electronics. 
The altimeter can display altitude in feet or meters, local pressure can be set in millibars or inches 
or mercury.
