The CHT-100 is a color CHT instrument that provides real-time display of each cylinder, in either automatic (hottest cylinder), timed step mode or single selected cylinder. These instruments are available four and six cylinder configurations. Instruments with a “V” suffix contain a full function voltmeter on an additional display screen, selectable using the control switch. Cylinder head temperature functionality is TSO'd and meets the temperature accuracy requirements of SAE AS8005 for a Class IIa (+/- 1%) instrument. The STC applies to 699 different aircraft models. These instruments and kits are certified as primary replacement instruments.

Functional displays include:

• Hottest cylinder selects the hottest cylinder at any given time
  
• Step mode sequentially scans all cylinders at a 5 second scan rate
  
• Single cylinder mode allows one specific cylinder to be monitored
  
• The optional voltmeter screen displays
  the bus voltage
  
• Intensity control is via the front panel control switch or external intensity
