Includes custom protective cushioned storage case, 3 AA batteries, instructions and a 24-Inch of reflective tape (additional tape widely available at hardware and other stores). ## Features - TACHOMETER VS. SPEEDOMETER: While a digital speedometer will read the current speed of a vehicle, this automotive tachometer is used for measuring the rpm of a revolving shaft, as with the driveshaft of an automobile. - ACCURATE RPM METER: This handheld tachometer is highly accurate and noncontact. With high-speed laser-aim operation and instant readings from 2.5 to 99,999 rpm, this radar gun gives you accurate rotational speed readings from a distance. - AUTOMOTIVE TACHOMETER GAUGE: This big- or small-engine tachometer measures velocity in revolutions per minute. The information is displayed on a large and easy-to-read LCD screen. - TECHNICAL SPECIFICATIONS: This pocket radar device is accurate to +/- 0.05% and is capable of measuring at a distance from 2" to 20". It measures revolutions over a 1-second sampling time and stores them as the last, minimum, or maximum reading. - COMPACT DIGITAL COUNTER: The compact, lightweight design of this photo tachometer makes it easy to get speed readings for diagnostic and measurement purposes. This device operates on 9v battery (included). ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000I5LDVC | | Best Sellers Rank | #6,388 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #1 in Industrial Tachometers | | Brand Name | NEIKO | | Color | Black | | Customer Reviews | 4.2 4.2 out of 5 stars (2,713) | | Global Trade Identification Number | 00837013207139 | | Included Components | Digital Tachometer | | Item Dimensions | 6.25 x 4.25 x 1.75 inches | | Item Weight | 6.4 ounces | | Manufacturer | Ridgerock Tools Inc. | | Measurement Type | rpm | | Model | 20713A | | Number of Items | 1 | | Number of Packs | 1 | | Part Number | 20713A | | Power Source | Battery Powered | | Style Name | Tachometer | | UPC | 837013207139 | | Unit Count | 1 Count | | Warranty Description | Limited lifetime Warranty | ## Product Details - **Brand:** NEIKO - **Color:** Black - **Item Weight:** 6.4 ounces - **Power Source:** Battery Powered - **Style:** Tachometer ## Images ![20713A Digital Tachometer, Noncontact Laser Photo Sensor with 2.5 to 99,999 RPM Accuracy, RPM Gauge Marker with Batteries Included - Image 1](https://m.media-amazon.com/images/I/81LQdBFo7IL.jpg) ## Questions & Answers **Q: where do you get replacement tape** A: Instead of paying a $1 per strip, I use HVAC foil tape I had laying around the house. Only $10 for a 150-feet roll ($8 at HD/Lowes). Something like this https://www.amazon.com/Homemory-Aluminum-Inches-Yards-Furnace/dp/B01M7S4APP/ref=sr_1_7?s=industrial&ie=UTF8&qid=1506079959&sr=1-7&keywords=hvac+foil+tape **Q: Can a reading be taken on the end of a 5/8" dia shaft, or do you have to put the reflective tape on the side of the shaft and aim laser from the side?** A: You can make a "flag" out of reflective tape and wrap it around the shaft, then all you need to do is aim the tach at the flag (not the center of the shaft). If you're still having trouble, try holding a 3x5 note card with it's edge aligned (parallel) with the center line of the shaft so that only 1/2 of the shaft is visible to the device, then it will only be able to measure the flag one time per rotation and it won't accidentally pick up the flag's reflection twice as it goes around. **Q: how is the battery life when not in use... I had one similar to this one and if i left the battery in it would kill them. anyone else have this prob?** A: I received mine in December 2018. I use it infrequently. Up till now (about six months) the battery is still good and working well. **Q: I know this unit can read off the RPM, but does it also count a number of revolution?** A: It does not count the total number of revolutions. You would have to do the math (RPM x minutes). This is a basic unit that shows a minimum and maximum value (RPM) obtained during a reading. It also requires reflective tape to be applied on the shaft (or rotating object). It's not a unit that you can just point and shoot and come up with various readouts. ## Frequently Bought Together - NEIKO 20713A Digital Tachometer, Noncontact Laser Photo Sensor with 2.5 to 99,999 RPM Accuracy, RPM Gauge Marker with Batteries Included - 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 - EHDIS Digital LCD Photo Tachometer Non-Contact RPM Meter Motor Speed Gauge Gun Style Includes 10 Reflective Tapes --- ## 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.co.za/products/2719719-20713a-digital-tachometer-noncontact-laser-photo-sensor-with-2-5](https://www.desertcart.co.za/products/2719719-20713a-digital-tachometer-noncontact-laser-photo-sensor-with-2-5) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-09-21*
