Brief Introduction:

This upgraded LCD Tachometer combines precision RPM tracking with voltage monitoring in one compact unit. Featuring a sun-shade design for clear reading under direct sunlight, a chrome-finished wear-resistant frame, and 3D textured surface for comfortable touch, this Digital RPM Gauge delivers reliable performance for monitoring your engine's real-time speed and electrical status at a glance

Technical Parameter:

Dimensions: 75 × 100 × 50 mm; Power supply: DC 9–36V; Operating temperature: -10℃–50℃; Humidity: ≤90% RH; Speed range: 50–9999 RPM; Signal frequency: 20 Hz–20 KHz; Accuracy: ±1%; Voltage alarms: >30V (overvoltage), 16–20V (warning), <10V (undervoltage); Speed alarm: >6000 RPM (default, customizable)

Application:

This universal Engine Tach Gauge works with 12V and 24V systems, suitable for cars, trucks, SUVs, RVs, boats, and industrial machinery. Its wide voltage compatibility and rugged design deliver consistent, reliable RPM tracking for both daily driving and heavy-duty commercial applications

Features:

Equipped with a sun-shading hood for glare-free visibility, a chrome screen frame for wear and heat resistance, and a visual speed bar for instant RPM feedback. The over-speed alarm is user-customizable beyond the default 6000 RPM. Built with imported key components for higher precision and longer service life

Quick Calibration:

Calibration is required on first use. Start the engine at steady idle, long-press the button >5 seconds to enter settings, and wait >5 seconds for auto-calibration — the gauge then displays real-time engine speed. Accurate manual calibration also supported for any engine type
