Accurate and Contactless RPM Measurement

The NCTM-500 uses a visible laser beam to reliably measure rotations of moving objects without physical contact. Its 650 nm wavelength laser combined with a wide measuring range (2.5 to 99,999 RPM) ensures versatility for different machines and applications, maintaining an accuracy of (0.05% + 1 digit) and providing quick results with its 1-second response time.

Convenient Memory Backup and User-friendly Features

This tachometer automatically stores the last, maximum, and minimum readings for easy record-keeping, and it indicates when the battery is low. The ergonomic, lightweight ABS body and large LCD digital display allow comfortable handheld operation. All necessary accessories-reflective tapes, a user manual, and battery-are included for immediate use.

Ideal for Industrial and Laboratory Applications

Designed for professionals in India, the NCTM-500 suits a wide array of settings-from factories monitoring motor speeds to laboratories performing RPM tests. Its non-contact nature enhances safety and reduces machine wear, while its compact and portable design makes it convenient for field measurements.

FAQ's of Metravi NCTM-500 Non-contact Type Tachometer:

Q: How does the NCTM-500 Non-contact Tachometer measure RPM?

A: It operates by shining a 650 nm laser beam onto a reflective tape attached to the rotating object. The tachometer detects the reflected laser pulses as the object rotates, calculating the RPM without physical contact.

Q: What is the recommended distance for accurate measurements?

A: Effective RPM measurements can be obtained when the tachometer is held 50 to 500 mm away from the target, ensuring the laser beam adequately reflects off the tape for precise readings.

Q: When should I use the memory backup feature?

A: Utilize the automatic memory backup to review or record the most recent, maximum, and minimum RPM readings. This is especially useful for sequential tests or comparative analysis during machine performance checks.

Q: Where can the NCTM-500 be applied effectively?

A: This tachometer is ideal for use in manufacturing plants, workshops, laboratories, and other settings where non-contact RPM measurement of rotating machinery, motors, or parts is required.

Q: What is the process for setting up the device for measurement?

A: Simply affix the reflective tape on the rotating part, power on the tachometer using the included 9V battery, aim the laser at the tape, and read the RPM value on the LCD display. The process is manual and straightforward.

Q: How does contactless measurement benefit users?

A: Contactless measurement prevents wear and tear of both instrument and machinery, increases operator safety, and enables RPM readings on high-speed, small, or inaccessible rotating components.
