JJCOCO 1832°F Pyrometer Kit

This JJCOCO kit provides high precision (±0.5% accuracy) across 32–1832°F, with an NPT 1/8″ sensor thread for a secure, leak-proof installation. It includes a sunlight-readable LED display and adjustable warnings for overheating. The kit is designed for 12V power, and its Type K probes offer universal sensor compatibility, making it suitable for cars, trucks, off-road vehicles, and marine systems that require robust diagnostics.
LEVANLIGHT 7 Color LED EGT Gauge Kit

The LEVANLIGHT kit covers temperatures up to 1200℃ with a 2-1/16″ gauge, black dial, and a seven-color LED display. The kit supports multiple color modes and dimming via the headlight switch, allowing seamless customization to match interior lighting. It includes an EGT sensor and mounting hardware, delivering a straightforward setup for cars and trucks while ensuring readable diagnostics in varying lighting conditions.
Buying Guide: Key Purchase Considerations
- Temperature range: Choose a gauge that covers your engine’s typical EGT range; higher ranges are essential for tuning and hot-running diesel engines.
- Display readability: Look for bright, easily readable displays with adjustable brightness and color options to suit day and night driving.
- Alarms and warnings: Programmable high-temp alarms help prevent overheating. Some models offer audible alerts and peak memory functions for tracking peak temperatures.
- Sensor connectivity: Ensure a compatible sensor thread (NPT 1/8″, Type K), and verify whether the kit includes all mounting hardware and a wiring harness for your installation scenario.
- Installation complexity: Kits vary from plug-and-play with minimal wiring to more extensive setups requiring more wiring. Consider your comfort level and tools available.
- Durability and environment: If installing in off-road or marine contexts, select water-resistant housings and rugged construction to withstand harsh conditions.
- Aesthetic integration: Seven-color displays and dimming options help you harmonize the gauge with your vehicle’s interior lighting and style.
- Compatibility: Some kits blend EGT and turbo boost sections; verify you’re selecting a dedicated EGT gauge or a combined package if you also want boost monitoring.
Overall, these options balance direct engine protections with clear visual cues, enabling drivers to act quickly when temperatures rise. Consider how your vehicle, usage patterns, and preferred interface influence your final choice, then follow the included instructions to install and calibrate the gauge for accurate readings.
