Installation Instructions 

Alcor Leads

• High quality stranded material for flexibility and long life
  (cheapy single stranded leads are prone to break)
• Used to attach a thermocouple probe to a gauge
• Must be of the same type as the thermocouple
  (e.g. A type K probe must use type K leads)

CHT Leads:

• Integrated resistor ensures the same resistance regardless of length
• Choose leads based on the distance from the probe to the gauge

EGT/TIT Leads:

• Each length has a different resistance
• Total resistance of the lead and the probe must match the calibration of the gauge
• Choose replacement leads based on the calibration of the existing gauge
• For a new system, choose leads based on the distance from the probe to the gauge and choose a gauge with the corresponding calibration.

ALCOR Instruments and Probes

Don't waste your money on cheap instruments and probes. There is a big difference!

Increase engine life and enhance safety through proper monitoring

• Faster responding probes than low dollar alternatives
• Temperature compensated gauges for accuracy all year round at any altitude
• Single gauges monitor one cylinder, dual gauges for twin engine aircraft monitor one cylinder per engine. Add a selector switch to make an economical full engine analyzer. Lighted gauges and custom dials also available!

Alcor: A name you can trust

• Over 50 years experience - Designed, manufactured and supported in the USA
• Generous warranty: 3 years for gauges, 5 years for grounded probes, 1 year for ungrounded probes
• FAA-PMA/STC approved for all aircraft with reciprocating engines

Simple installation

• No power required from the aircraft (lighted gauges require power)
• Works even with an electrical failure
• Great for homebuilt or antique aircraft with no electrical system
• Gauges include all mounting hardware
• Standard 2 1/4" or 3 1/8" gauge sizes
