accurate temperature measurement

I just bought an interesting bit-o-kit.

Features

• Compatible with any of our EGT probes & CHT sensors
• Accepts up to12 probes
• High resolution LCD display with backlighting
• Temperatures can be displayed in °C or °F; from -100 to +1200ēC (-148 to +2192°F)
• Display up to 12 channels in an easy to read bargraph format
• Visible high temperature alarm; LED changes to red color
• Recall Max Peak temperature memory Button
• Power from either 12 VDC or 24 VDC
• Supports J, K, & E thermocouple probes

The 12-channel digital thermocouple pyrometer gauge display is 3-1/8” instrument that contains all the features necessary to monitor EGTs and/or CHTs. The instrument is fully programmable by the user resulting in the most flexible solution available. The gauge display can be configured to display up to 12 thermocouples in an easy to read bargraph format.

Features

Engineered for high horsepower applications!
• EGT-IP series
• Set of 8 EGT probes • Probe diameter 1/4 inch (0.250 inch)
• Exposed Tip Sensing Junction (Fast Response)
• Response time constant: 150 milliseconds
• Includes 316 SS adjustable compression fitting
(Recommended for fuel types: Gasoline, Nitromethane, & Alcohols)
I ordered 12 total 1/4" 125 ms response EGT K-type probes (125 ms to respond/start to react will take 5X the response time to read full. AKA 125ms =625 ms/ .625 sec) other more common response times 250,550, and 1200 ms.(1.25, 2.7, and 6 sec) the gage has a 1 sec refresh rate. The more comin probes need 1-6 refreshes to show engine damaging overheat condition.

I have a 6 cyl, so 6 ports will read individual cylinders 3 will measure intake air ambient (pre turbo), charge air (pre intercooler), and intake air temp just under the grid heaters in the manifold.

i also got (all with 12' leads)
some weld on probes
some stick ons
what would you like to see tested ?
oil temp rise compared to coolant temp rise.
how the grill block effects coolant , oil, trans , under hood/ IAT

What do you think ? Did Cummins properly balanced the fuel sys AKA each burning at the same air fuel ratio/ temp (the richer the hotter/ smokier)

Dream Big Chisel Down To Reality
