Product Description

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

CHT Type J Black and Yellow
P/N	Resistance	Length
42535	7.76 +/- .20 Ohms	90"
42536	7.76 +/- .20 Ohms	144"
42543	7.76 +/- .20 Ohms	216"
42537	7.76 +/- .20 Ohms	240"

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.

EGT Type K Red and Yellow
P/N	Resistance	Length
42525	4.34 +/- .08 Ohms	90"
42526	2.71 +/- .06 Ohms	144"
42528	6.52 +/- .11 Ohms	216"
42527	7.25 +/- .12 Ohms	240"

Calibration note:
EGT gauges with relative lean to peak markings may be easily recalibrated in flight per the instructions provided with the gauge. TIT, CHT and EGT gauges with True Temperature markings must either be recalibrated with an Alcal System Tester or returned to Alcor for recalibration if the total lead and probe resistance does not match the gauge calibration.

Digital or amplified gauges from other manufacturers are not sensitive to lead resistance, therefore leads may be shortened as needed for these applications without requiring recalibration.

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
