Digital Photo Tachometer RPM Meter Non-Contact Non-Magnetic Engineer's Precision Level Device

A Digital Non-Contact Laser Tachometer is a high-precision instrument designed to measure rotational speed (RPM) of moving objects without direct contact. It uses a laser or infrared beam to detect reflective tape placed on the rotating surface, ensuring safe, accurate, and reliable speed readings from a distance.

Key Features:

✅ Non-Contact Measurement – Uses a laser sensor for accurate RPM readings without physical contact.
✅ High Accuracy – Typically provides ±0.05% accuracy with a high-resolution digital display.
✅ Wide Measurement Range – Covers 2.5 to 99,999 RPM (varies by model).
✅ LCD Backlit Display – Large, clear display for easy reading in different lighting conditions.
✅ Data Hold & Memory – Stores last measured values (min/max/average).
✅ Portable & Durable – Compact, lightweight design with ergonomic grip.
✅ Battery Powered – Operates on standard AA or 9V batteries for convenience.

Applications:

🔹 Industrial machinery speed monitoring
🔹 Automotive engine RPM measurement
🔹 Fan, motor, and conveyor speed testing
🔹 HVAC systems and mechanical maintenance

Main Difference:

• DT-2234C: Only supports non-contact RPM measurement.

• DT-2236C: Supports both non-contact and contact RPM measurement, making it more versatile for different applications.
