Real-World Testing: Putting Unico Tachometer Photo w/ Reflective Tape, Batteries & Storage Case to the Test

First Use Experience

My first real-world test of the Unico Tachometer Photo w/ Reflective Tape, Batteries & Storage Case took place on a standard laboratory bench, in front of a benchtop centrifuge that had recently undergone routine service. The process was remarkably straightforward. I applied a small strip of the provided reflective tape to one of the centrifuge’s rotor arms—a simple peel-and-stick operation that took mere seconds.

I then positioned the photo tachometer a short distance away, aiming the optical sensor directly at the rotating tape. Powering it on was as easy as pressing a single button, and the display immediately began to flicker with readings. I initiated a run cycle on the centrifuge at a moderate speed, around 2000 RPM. The tachometer’s screen stabilized quickly, displaying a reading that was within a few RPM of the centrifuge’s own dial, a promising start. I then increased the speed to its maximum setting. The device handled the higher RPMs without any sign of struggle, providing a consistent and clear readout that closely matched the centrifuge’s indicated speed.

The unit performed admirably in the controlled lab environment. The ambient fluorescent lighting didn’t interfere with the optical sensor’s ability to detect the reflective tape, and the consistent rotation of the rotor provided a stable target. There was no perceptible lag in the readings, and the display was bright enough to be easily read even with some overhead glare. The tactile feedback from the buttons was positive and distinct, ensuring I knew when a command had been registered. It felt intuitive; there was no need to consult a manual for basic operation, which is a significant plus when you need to perform a quick calibration check.

The only minor surprise was the sensitivity of the optical sensor; I found that slight movements of the tachometer could cause the reading to fluctuate momentarily. However, this was easily corrected by ensuring a stable grip and a direct line of sight to the reflective tape. This reinforced the importance of proper technique when using any optical measurement device.

Extended Use & Reliability

After several weeks of consistent use, involving checks on multiple centrifuges and occasional use on other rotating equipment in the workshop, the Unico Tachometer Photo w/ Reflective Tape, Batteries & Storage Case has proven itself to be a reliable workhorse. It has become an indispensable part of my routine equipment calibration checklist. The device has been used during checks where dust is present from general workshop activities, and the optical sensor has held up well, with no degradation in its ability to pick up the reflective tape.

Durability has been surprisingly good. Despite being moved around the lab and workshop frequently, and even experiencing an accidental, minor bump against a workbench edge, there are no visible cracks or performance issues. The plastic casing, while not heavy-duty industrial grade, feels robust enough for its intended purpose. The reflective tape itself has adhered perfectly to the rotor arms, showing no signs of peeling or degradation, even after repeated exposure to lubricant and general lab grime.

Maintenance has been minimal, which is a major advantage. The primary care involves wiping down the tachometer’s housing and lens with a soft, dry cloth. The reflective tape, when it eventually needs replacing (which I estimate will be after many months of use, given its current condition), is easily peeled off and reapplied. The batteries, which are standard AAAs, are also simple to replace by sliding open a small compartment on the back. Compared to older, analog tachometers I’ve used in the past, this optic is far simpler to maintain and far less prone to mechanical failure. It also significantly outperforms basic strobe tachometers that require careful synchronization and can be prone to misreads at high speeds or with uneven reflective patterns.
