Tachometer Price in Bangladesh | Digital & Non-Contact RPM Meter

If you’re comparing Tachometer price in Bangladesh before buying, ASTZ carries genuine Lutron and Smart Sensor tachometers covering both digital contact and non-contact laser measurement, from a budget-friendly ৳3,000 mini unit up to a professional ৳26,000 dual-function model. Whether you’re checking engine RPM on a production line or measuring motor speed without touching a hazardous rotating part, this guide breaks down every option so you can pick the right one without guesswork.

Types of Tachometer Available at ASTZ

Not every tachometer measures RPM the same way. Here’s how our range is organized.

Digital Tachometer (Contact & Non-Contact)

The Lutron DT-2236 Digital Tachometer, priced at ৳26,000, delivers precise digital RPM readings for demanding industrial and lab use, with the accuracy and build quality expected from a Taiwan-made professional instrument.

Photo/Contact/Laser Tachometer

The Lutron DT-2238 Tachometer, priced at ৳24,500, combines photo, contact, and laser measurement modes in one unit — a flexible choice when your work requires switching between direct-contact and non-contact readings depending on the job.

Non-Contact Digital Tachometer

The SMART SENSOR AR926 Non-Contact Digital Tachometer, priced at ৳3,000, is a precision RPM meter built for quick non-contact readings, making it the most accessible entry point in our tachometer range.

Pricing depends on measurement mode and brand precision, so it’s worth matching the model to your actual application before ordering.

Contact vs Non-Contact Tachometer — Which One to Choose

Contact Tachometer — For Direct Shaft/Wheel Contact Measurement

A contact tachometer touches the rotating shaft directly, which works well for accessible, low-speed components where physical contact won’t disturb the measurement or pose a safety risk.

Non-Contact Tachometer — For Hard-to-Reach or Hazardous Rotating Parts

The SMART SENSOR AR926 and the non-contact mode on the Lutron DT-2238 use a laser or infrared beam to read RPM from a distance, ideal for high-speed motors, fans, or any part where touching the shaft isn’t safe or practical.

How to Use a Digital Tachometer

Setting Up for Contact Measurement

Attach the tachometer’s contact wheel to the rotating shaft or center point, hold it steady, and read the RPM directly off the digital display once the reading stabilizes.

Setting Up for Non-Contact (Laser) Measurement

Apply a small piece of reflective tape to the rotating object, aim the tachometer’s laser at the tape from a safe distance, and the device will register RPM as the laser detects each pass of the reflective marker.

Top Tachometer Brands We Offer

Lutron Tachometer

Lutron covers our higher-precision range, with the DT-2236 for dedicated digital measurement and the DT-2238 for flexible multi-mode readings — both built in Taiwan for reliable industrial use.

Smart Sensor Tachometer

Smart Sensor’s AR926 gives you accurate non-contact RPM readings at an accessible price point, making it a practical choice for general workshop and maintenance use.

How to Choose the Right Tachometer (Buying Guide)

Contact vs Non-Contact Based on Your Application

If your rotating part is small, accessible, and safe to touch, a contact tachometer works fine. For high-speed, hard-to-reach, or hazardous components, non-contact measurement is the safer and often more practical choice.

Precision & Application Level

The Lutron DT-2236 and DT-2238 suit industrial and lab environments needing tighter precision, while the SMART SENSOR AR926 covers general workshop and maintenance-level RPM checks.

Single-Mode vs Multi-Mode

If you regularly switch between contact and non-contact measurement depending on the job, the Lutron DT-2238’s combined photo/contact/laser functionality saves you from needing two separate tools.

Frequently Asked Questions

What is a tachometer used for?

A tachometer measures the rotational speed of a shaft, motor, or engine in RPM (revolutions per minute), commonly used for engine diagnostics, industrial machinery monitoring, and maintenance checks.

What is the difference between a contact and non-contact tachometer?

A contact tachometer touches the rotating shaft directly to measure speed, while a non-contact tachometer, like the SMART SENSOR AR926, uses a laser or infrared beam to read RPM from a distance without physical contact.

How accurate is a digital tachometer?

Digital tachometers like the Lutron DT-2236 offer precise, repeatable RPM readings suitable for industrial and lab use, generally more accurate and easier to read than analog dial-based models.

What is the price of a tachometer in Bangladesh?

Tachometer prices at ASTZ range from ৳3,000 for the SMART SENSOR AR926 non-contact model up to ৳26,000 for the Lutron DT-2236 professional digital tachometer.

Can a tachometer measure the RPM of a car engine?

Yes, tachometers are commonly used to measure engine RPM, though the correct measurement method (contact or non-contact) depends on which part of the engine you’re testing.

Does a tachometer need calibration?

Most digital tachometers hold their calibration well under normal use, but periodic accuracy checks against a known reference are recommended for critical industrial or lab applications.

What is the difference between analog and digital tachometers?

An analog tachometer uses a needle and dial to show RPM, while a digital tachometer, like our Lutron and Smart Sensor models, displays the reading numerically on an LCD screen for faster, clearer results.
