ZHSYMX Exhaust Gas Temperature (EGT) Gauge Kit 52mm Digital — LED Readout & Programmable Alarm

ZHSYMX Exhaust Gas Temperature (EGT) Gauge Kit is a compact 52mm digital pyrometer package with a threaded probe, LED readout, programmable alarm and peak memory for monitoring exhaust temperature.

Keep a close eye on exhaust gas temperature to help you spot abnormal engine conditions early. The ZHSYMX kit combines a clear digital gauge head, a rugged EGT probe, mounting hardware and a simple two-button interface so you can install, view and set alerts quickly. The ABS housing and compact 2-1/16" (52mm) footprint fit most dash openings and tolerate a range of operating climates.

How does the display show temperature and alerts?

The gauge uses a bright red LED numeric display with a white background and a sweeping LED needle to present real-time EGT readings. You can set a threshold alarm that triggers an indicator when temperatures exceed your chosen limit, plus recall peak values later.

• Numeric LED shows precise temperature values.
• Sweeping LED gives an easy visual trend at a glance.
• Programmable alarm point for threshold warnings.
• Peak memory and recall function store highest readings.

What components come in the kit and how easy is installation?

The kit includes the digital gauge head, a compatible EGT probe, necessary mounting hardware and basic wiring. The included probe is designed to fit and work out of the box, reducing the need to source additional sensors or parts.

• Complete gauge head and threaded EGT sensor included.
• Mounting bezel, clamp and screws ready for 52mm dash holes.
• Simple two-button controls for setting and recalling values.
• Clear wiring leads for power, ground and signal connections.

What build quality and environmental resistance does the gauge offer?

The housing is molded from high-hardness ABS plastic engineered for thermal stability and impact resistance. That makes the unit suitable for a range of vehicle and climate conditions while protecting internal electronics.

• Durable ABS housing resists heat and vibration.
• Compact 52mm size fits common gauge pods and dash cutouts.
• Sealed connections reduce exposure to dust and moisture.
• Manufactured components meet typical automotive installation needs.

How do controls and memory functions help during driving?

Two programmable buttons let you set an alarm threshold and recall peak readings without complex menus. The combination of a digital readout plus a sweeping LED needle helps you monitor both exact values and trends while driving.

• Two-button interface for quick programming and recall.
• Peak memory stores highest recorded EGT for post-run checks.
• Threshold alarm provides audible/visual warning when set value exceeded.
• Standard and metric display options for user preference.

Who is this for: The ZHSYMX EGT Gauge Kit is aimed at tuners, diesel truck owners, performance motorists and shop technicians who want a straightforward, compact solution to monitor exhaust gas temperature. It’s ideal when you need a plug-and-play sensor with clear readout, programmable alarms and durable construction for regular automotive use.
