GlowShift Black 1500F Pyrometer EGT Gauge Kit
The GlowShift Black 1500°F EGT gauge is designed to monitor diesel exhaust temperatures to prevent overheating. It features a 2-1/16″ (52mm) diameter gauge with a black dial, illuminated red needle, and a clear lens. Seven solid color modes plus two color cycle options let you match factory dashboard lighting or customize the interior. It includes a Type K EGT probe and wiring for straightforward installation. The dimmer wire can be tied into the headlight circuit to reduce brightness by about 30% when headlights are on, helping readability at night.
GlowShift Tinted 2400F EGT Gauge Kit
The GlowShift 2400°F EGT gauge is ideal for higher-heat applications, such as tuned diesel engines. It uses a tinted lens for reduced glare and a 2-1/16″ gauge with a black dial and red illumination. With seven color modes and two cycle options, it supports seamless integration with your interior lighting. The kit includes a 1/8-27 NPT Type K probe and wiring. As with other GlowShift products, dimming is possible via the headlight switch, improving visibility in night driving.
JJCOCO EGT Gauge Kit 1832℉
JJCOCO’s EGT kit provides a high-precision readout from 32°F to 1832°F with professional calibration (±0.5% accuracy). Its Type K probe offers universal compatibility across engines, while the sunlight-readable LED display ensures legibility in bright conditions. The included sensor and wiring simplify installation for cars, trucks, ATVs, and marine applications. The water-resistant housing enhances durability in harsh environments, and the kit supports easy setup of temperature alerts for overheating or critical temps.
GlowShift 10 Color Digital 2200F EGT Gauge Kit
The GlowShift 2200°F digital EGT gauge offers a bright, easy-to-read LED display with 10 selectable color modes and two color cycles. Its digital readout covers a broad range (200–2200°F) and includes a self-calibration feature at startup to ensure accuracy. The kit comes with a Type K probe and wiring, plus a tinted lens and a black housing for a clean dashboard look. It’s suitable for car, truck, and off-road installations where quick temperature awareness matters.
MaxTow Double Vision 1500F EGT Gauge Kit
MaxTow’s Double Vision 1500°F gauge combines analog and digital readouts in a single unit, with green LED lighting and a clear lens for easy daytime and nighttime readability. The 2-1/16″ gauge includes a Type K EGT probe and wiring for diesel truck applications. The dual-display design allows quick cross-checking of readings, which can be advantageous when diagnosing varying exhaust temperatures along a route or in different operating conditions. Dimming options are available to suit ambient lighting preferences.
MaxTow Double Vision 1500F (Blue LED Dial)
This MaxTow variant features a blue LED dial with the same Double Vision concept, blending analog and digital readouts for a comprehensive temperature overview. The 0–1500°F range and Type K probe support diesel truck installations, while the blue illumination offers a distinct nighttime look. The product emphasizes durability and versatile mounting options, making it a practical choice for enthusiasts who want a visible, flexible gauge kit with reliable performance.
Buying Guide: Key Considerations When Choosing an EGT Probe And Gauge
- Temperature range: Ensure the gauge covers the expected exhaust temperatures for your engine setup. Diesel apps often require higher ranges (up to 2400°F) for tuned systems, while stock setups may suffice with 1500°F.
- Display type: Analog gauges with color LEDs offer quick at-a-glance readings, while digital displays provide precise numbers. Consider readability in bright daylight and at night.
- Probe compatibility: Most kits use a 1/8-27 NPT Type K probe, which works with many engines. Check thread size and sensor material to prevent leaks and ensure accurate readings across environments.
- Lighting and visibility: Dimming options and tinted lenses reduce glare. If your vehicle’s interior lighting is bright, select a model with multiple brightness settings.
- Durability and mount: Look for water-resistant housings and robust materials designed for harsh engine compartments. Gauge size should fit your dash or pillar pod without obstructing visibility.
- Installation complexity: Some kits require only wiring to power and dimming control, others involve sensor installation and routing. If you’re not confident, seek professional installation or a kit advertised as easy to install.
- Additional features: Dual readouts (analog/digital), color-cycle modes, and alarms or warnings can help in proactive engine management and diagnostic conversations with mechanics.
- Compatibility: For modern vehicles, ensure the gauge does not interfere with other dash electronics and that it uses standard sensor types compatible with your engine’s exhaust system.
In choosing an EGT probe and gauge, balance measurement range, display readability, and installation effort. The options above cover a spectrum from simple analog-readout kits to digital, multi-color displays with robust probes. Consider whether you prioritize high-temperature range, color customization, or dual readouts for comprehensive monitoring. This will help you select a gauge that fits your vehicle, driving style, and maintenance goals.
