Extech Instruments Photo/Contact Tachometer RPM Surface Speed And Memory 2700

The Extech 2700 is a versatile, professional-grade tachometer designed for accurate measurement of rotational speed (RPM) and surface speed. Uniquely combining both non-contact (photo/laser) and contact measurement modes in one rugged tool, it’s the ultimate solution for maintenance technicians, mechanics, and production engineers. With a built-in memory function that stores up to 100 readings, the 2700 simplifies data logging and troubleshooting for a wide range of industrial and automotive applications.

Key Features & Benefits (H2)

• Dual Measurement Modes: Measure RPM from a safe distance using the non-contact laser reflex method, or switch to contact mode for direct drive applications using the included contact tips.

• Measures RPM & Surface Speed: Get readings in Revolutions Per Minute (RPM) for motors, shafts, and fans, or in Surface Speed (Feet/Minute or Meters/Minute) for belts, pulleys, and conveyor systems.

• Large Memory Function: Store and recall up to 100 measurements, allowing you to track speed variations over time or document conditions without manual note-taking.

• High-Accuracy Laser Sensor: The non-contact mode provides precise measurements from 5 to 50,000 RPM, ideal for fragile or hazardous machinery where physical contact is not possible.

• Complete Kit: Comes ready-to-use with a reflective tape roll, contact tips, a 4″ rubber wheel for surface speed, and a protective carrying case for organization and portability.

• Easy-to-Read Backlit Display: The large LCD with backlight ensures clear visibility of readings, even in poorly lit workshops or dim industrial environments.

The Ultimate Tool for Precision Speed Measurement

The Extech Instruments 2700 Tachometer is an indispensable diagnostic and maintenance tool for anyone who needs to measure rotational or linear speed. Engineered for versatility and reliability, it eliminates the guesswork in machinery setup, quality control, and preventive maintenance.

How It Works:

• In Non-Contact (Photo) Mode: Simply place a small piece of the included reflective tape on the rotating object. Aim the 2700’s laser beam at the tape, and it will calculate the RPM based on the reflected light pulses. This is perfect for measuring fans, spindles, and motors without disrupting operation.

• In Contact Mode: Attach one of the provided contact tips or the rubber wheel to the probe. Press the tip against the center of a rotating shaft or surface, and the 2700 will directly measure the RPM or surface speed. This mode is essential for lathes, drills, and conveyor belts.

Why Choose the Extech 2700?

• Versatility: One tool does the job of two. Save money and toolbox space by having both contact and non-contact capabilities.

• Data Logging: The 100-reading memory is a critical feature for troubleshooting intermittent problems and creating maintenance reports.

• Safety and Convenience: The non-contact laser allows for safe measurement of hot, electrically live, or otherwise inaccessible equipment.

• Professional Results: Achieve optimal machine performance by accurately setting speeds for motors, VFDs (Variable Frequency Drives), and production line equipment.
