01AUTOMOTIVE GAUGES
Precision in every rotation
Mounted securely within the engine bay or workshop bench, this compact instrument offers a continuous window into mechanical performance. The black casing blends seamlessly with industrial aesthetics while the illuminated digits provide immediate clarity.
Designed for engineers and hobbyists alike, it tracks rotational speed with high stability. Its broad measurement range suits diverse motor types, ensuring accurate data capture regardless of the application's specific demands.
02MATERIALS
Robust metal and plastic construction
The housing combines durable metal with sturdy plastic, creating a unit that withstands the vibrations and heat typical of motorized environments. This material choice ensures longevity without adding excessive weight to the installation area. The finish is matte black, reducing glare from surrounding lights.
04SENSORS
Hall switch detection mechanism
The included Hall proximity switch operates as an NPN normally open type, requiring the target to be within 10mm for optimal reading. Strong anti-interference capabilities allow for stable signals even near other electrical components. Users should ensure uniform rotation for consistent data.
INSTALLATION
Standard size easy setup
Designed for straightforward integration, the kit includes all necessary wiring: brown for power, black for test, and blue for signal. Parameters are memorized when power is off, preserving settings between sessions. Shielded wire or twisted pairs are recommended for conductors to minimize electromagnetic noise.

About this product
Easy to install, Suitable for detecting the speed of every kind of motors. Large measure range and large LED display, standard size, easy to install. Come with hall sensor, have good stability, high measurement precision. Setting parameters be memorized when power off. Strong anti-interference ability, can precisely test the rpm value for motors. Motor Type: for Motor Working Power Supply: 8-24V, 40mA Measure Range: 10 – 9999RPM Error Range: 0.1% Clear Zero: Automatic Display Refresh Rate: 3 Times / Second Sensor Wiring: Brown(Power+), Black(Test+), Blue(signal) Note: The hall switch is NPN normally open type, and the detection distance of the hall switch needs to be within 10mm. When the jump is too large, please check whether the test object rotates at a uniform speed and whether the installation is stable. Strong electromagnetic interference shall be avoided. It is best to use shielded wire or twisted pair for measuring conductor. Color: As Shown Material: Metal+Plastic Package Contents: 1 x Motor tachometer kit Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
