HT673 Pen-Style Laser Tachometer

Read rotational speed without placing a contact probe against the rotating part. The HT673 pen-style laser tachometer combines RPM measurement and revolution counting in a compact handheld instrument.

✅ Check rotation without physical probe contact - The optical measurement method reads a suitable rotating target from the permitted measurement position.

✅ Record a total when speed is not the question - The counting mode provides a separate function for tasks that need a revolution count.

✅ Read the result at the machine - The backlit LCD keeps the measurement indication on the handheld unit at the inspection point.

Choose Speed or Count for the Check

Use RPM mode when you need a rotation-rate reference, or select counting when the task calls for a total. Prepare the target according to the instrument instructions with the machinery stopped and safely isolated before arranging any measurement mark.

Keep guards and the measurement position appropriate for the machine, and confirm the instrument's working distance before taking a reading. The pen format and clip are practical for carrying between inspection points; two AAA batteries power the unit and are supplied separately.
