Works good. ### ⭐⭐⭐⭐⭐ Review *by M***E on 24 March 2023* Very good value. ### ⭐⭐⭐⭐ Review *by S***S on 14 July 2023* Good price, I like that a good amount of reflective tape was included. Accuracy verified with 2 methods; a calibrated signal generator (HP 3325B) and a tachometer calibrator (Sargent 1100A). The first method uses an LED from the output of the signal generator, set at specific frequencies, ex. 4.1667Hz should show 250rpm on the tach. I found this method to be slightly difficult, as the tach wouldn't always detect the LED (I used white and red LEDs). The second method uses a Sargent tachometer calibrator and a 20:1 ratio gear box (with a wheel that uses the reflective tape). That method worked better, as I was able to focus the tach's laser on the tape. I set the calibrator to 6000rpm and 20,000rpm. Both were dead on. So, the tach works well, you can trust the readout IF you can get it to display a constant, identical reading. I'd hold it on the target for 20-30 seconds and average the readings. 4 stars for the accuracy and price. ## Frequently Bought Together - EHDIS Digital LCD Photo Tachometer Non-Contact RPM Meter Motor Speed Gauge Gun Style Includes 10 Reflective Tapes - 20 Pieces Reflective Tape Tachometer Tapes Strips for Optical and Laser Reflective Sticker for Non-Contact Digital Photo Tachometers Accessories Optical and Laser Tach RPM - NEIKO 20713A Digital Tachometer, Noncontact Laser Photo Sensor with 2.5 to 99,999 RPM Accuracy, RPM Gauge Marker with Batteries Included --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/326486231-digital-lcd-photo-tachometer-non-contact-rpm-meter-motor-speed](https://www.desertcart.us/products/326486231-digital-lcd-photo-tachometer-non-contact-rpm-meter-motor-speed) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-22*
