A diesel EGT gauge kit helps you monitor exhaust gas temperature, or EGT, while driving or working your truck. The GlowShift 1500°F kit is best for a straightforward analog-style reading; its 2400°F model suits buyers who want a wider stated range. Digital-display options add features such as alarms or peak recall, while GlowShift’s three-gauge set also tracks boost and transmission temperature.
| Product | Best For | Stated EGT Range |
|---|---|---|
| GlowShift Black 7 Color Pyrometer | Analog-style monitoring | 0–1500°F |
| ZHSYMX Digital EGT Gauge Kit | Peak memory and alarm settings | Not stated |
| GlowShift Tinted 7 Color EGT Gauge | Wider temperature range | 0–2400°F |
| JJCOCO Digital Pyrometer Kit | Alarm and peak-recall features | Up to 1800°F |
| GlowShift Three-Gauge Diesel Set | Monitoring three engine readings | EGT: 0–1500°F |
GlowShift Black 7 Color 1500°F Pyrometer
This 2-1/16-inch analog-style pyrometer displays EGT from 0°F to 1500°F. It has a black dial, red illuminated needle, clear lens, matte-black trim ring, and aluminum housing. Seven solid color modes and two color-cycle modes let buyers choose among blue, red, green, teal, purple, white, and yellow illumination.
Best for: Diesel owners who want a conventional needle gauge and dashboard color options. It was selected for its clearly stated EGT range and configurable illumination. Connecting the dimmer wire to the headlight switch reduces brightness by 30% when the headlights are on.
Limitation: The stated display range ends at 1500°F, so compare that ceiling with the range you need before choosing.
ZHSYMX Digital EGT Gauge Kit
This kit uses a red LED display with a white background and includes a programmable alarm point, peak memory, and threshold warnings. Its two-button interface supports peak recall and a choice of standard or metric center LED readouts. A sweeping LED needle provides another visual way to follow temperature changes.
Best for: Buyers who prefer a digital readout with peak and threshold features rather than a basic dial. It was selected for its combination of warning settings and recall functions, which can help drivers check readings without relying on a needle alone.
Limitation: The supplied product details do not state the measurement range or describe the sensor and installation components. Confirm those specifications before purchase.
GlowShift Tinted 7 Color 2400°F EGT Gauge
This 2-1/16-inch gauge reads from 0°F to 2400°F. Its black dial, illuminated red needle, tinted lens, matte-black trim ring, and aluminum housing give it a different face treatment from the clear-lens GlowShift option. It also offers seven solid illumination colors and two color-cycle modes.
Best for: Buyers who want a needle-style gauge with a higher stated upper range than the 1500°F model. It was selected because the listed range reaches 2400°F and the selectable colors offer dashboard-matching flexibility.
Limitation: The tinted lens may not suit buyers who prefer a clear lens; consider the product’s appearance and your preferred viewing conditions.
JJCOCO 1800°F Digital Pyrometer Kit
The JJCOCO kit has a stated 1800°F capacity, a large red LED display, and a sweeping analog needle. Listed features include a programmable high-temperature alarm with flashing display, audible buzzer, and red needle warning, plus one-touch peak recall. The kit includes a 90-degree-bend sensor, mounting hardware, and wiring harness.
Best for: Buyers looking for a digital display and multiple alert cues, with installation components listed in the product details. It was selected for its alarm, peak-recall function, and specified 1800°F range.
Limitation: The feature description says installation is designed for self-installation, but buyers should still review the instructions and confirm the setup suits their vehicle.
GlowShift Three-Gauge Diesel Set
This set includes three 2-1/16-inch gauges: a 0–60 PSI boost gauge, a 0–1500°F EGT gauge, and a transmission-temperature gauge reading 80–260°F. Each has a black dial, red illuminated needle, clear lens, matte-black trim ring, and aluminum housing. The set provides seven solid colors and two color-cycle modes.
Best for: Diesel truck owners who want EGT alongside boost and transmission-temperature readings. It was selected because it combines three specified monitoring functions in one matching set.
Limitation: Choose another option if you only need an EGT gauge or want a stated EGT range above 1500°F.
Buying Guide: How To Choose A Diesel EGT Gauge Kit
What EGT range should you look for?
Compare the gauge’s stated upper range with the readings and operating conditions you need to monitor. The options here list limits of 1500°F, 1800°F, or 2400°F; the ZHSYMX details do not specify a range. A higher range provides more display capacity, but check that the product suits your intended use rather than choosing by maximum number alone.
Should you choose a digital or analog display?
Analog-style gauges show temperature with a needle and may offer selectable lighting. Digital options can include a numeric readout, peak memory, or alarms. If alerts and recall are priorities, compare the digital kits’ listed functions. If you prefer a traditional dial, consider the GlowShift pyrometers.
Do you need an EGT-only kit or a gauge set?
An EGT-only kit keeps the choice focused on exhaust temperature. A multi-gauge set is better for buyers who also want the specific boost and transmission-temperature readings included in the GlowShift set. Check each gauge’s stated range and size before selecting a group.
What should you check before installation?
Review the included sensor, wiring, mounting hardware, and instructions. The JJCOCO listing names a sensor, hardware, and harness, while the other descriptions provide different levels of installation detail. Verify that the kit’s stated components and display dimensions fit your intended installation.
Frequently Asked Questions
What does a diesel EGT gauge measure?
It displays exhaust gas temperature. These kits are designed to let drivers monitor EGT readings while operating a diesel vehicle.
What is a pyrometer gauge?
A pyrometer is a temperature-measuring instrument. In these product listings, “pyrometer” refers to a gauge kit for monitoring exhaust gas temperature.
Do all EGT gauges include an alarm?
No. The listed features vary. Alarm settings are specified for the ZHSYMX digital kit and the JJCOCO kit, but not for every product here.
Which option includes boost and transmission-temperature gauges?
The GlowShift three-gauge diesel set includes a boost gauge, an EGT gauge, and a transmission-temperature gauge.
