Ideal for conveyor belts and motors, it also supports multiple sensor inputs for voltage, current, temperature, and more, making it a versatile tool for professional-grade speed and physical quantity monitoring. ## Description Buy EEEkit 4 Digital Blue LED Tachometer, RPM Speed Meter Digital Motor with Hall Proximity Switch Sensor NPN for Conveyor Belts: Tachometers - desertcart.com ✓ FREE DELIVERY possible on eligible purchases Review: Works as advertised, very good value - Price is one of the best I found. No instructions are included, however the pictures on desertcart give a wiring diagram.. This is necessary because the "printing" on the case is almost too small to see. Plenty (actually more than enough) wire length is provided. Using this is quite valuable for me, the previous (from the factory) minimum speed was around 650 RPM, using this RPM indicator as a reference I was able to modify the speed drive to lower my minimum speed to near the 500 RPM I desired. Also I was able to see how fast this machine would go if the max speed stop is bypassed. The display can be mounted in a "project box" for a more professional appearance. (The current installation is temporary, and I haven't done this yet). The photos show my "temporary" installation". Demonstrating the device works as advertised. I assume it is accurate, although I do not have a standard to compare it to. RPM indications (in photos) show the limits of the machine (normal speed controls overridden to achieve top attainable speed). One slight negative, the display does not give "instant" response. Once speed changes it takes about a second to update. This isn't an issue but I felt obligated to point this fact out in the review. Review: Great and hackable - If you look at the circuit board there are places where extra buttons can be soldered in. Do this and you get a preprogrammed set of goodies. Stop watch, speed count, slower count, number stuff and stuff. 9 of the stuffs. If you have a temp probe the right Ω then it has a stuff for that too already programmed and ready to use, just need a button.. worth the price, every penny.. ## Features - High Accuracy: The measurement range is 10-9999rpm with 0.1% accuracy. Clear zero time in about 10 seconds. Response frequency: > 3 times/second. Voltage: DC 12-24V, Current: 40mA - Clear & Easy Reading: Features a blue 4-digit LED display for clear and easy to read. The digital LED tachometer size is about 80*25*40mm(L*W*H) - High Stability: Uses the latest A/D conversion chip, high stability reference IC, and stick chip components. Stable and fast response. Overrange display shows "1" or "-1" for thousands of units, with the last three digits not displayed - Settable Parameters: Parameters are memorized when powered off. Ideal for detecting motor speeds - Extensive Applications: The digital rpm gauge tachometer is suitable for measuring voltage and current, and can be an external sensor to measure temperature, pressure, displacement, and other physical quantities ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | EEEKit | | Item Weight | 0.09 Kilograms | | Item dimensions L x W x H | 4 x 8 x 2.5 inches | | Manufacturer | EEEkit | | Material | Plastic | ## Product Details - **Brand:** EEEKit - **Material:** Plastic - **Item dimensions L x W x H:** 4 x 8 x 2.5 inches - **Item Weight:** 0.09 Kilograms - **Manufacturer:** EEEkit ## Images ![4 Digital Blue LED Tachometer, RPM Speed Meter Digital Motor with Hall Proximity Switch Sensor NPN for Conveyor Belts - Image 1](https://m.media-amazon.com/images/I/31fgqGkyN8L.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works as advertised, very good value *by G***Y on January 13, 2020* Price is one of the best I found.

Do this and you get a preprogrammed set of goodies. Stop watch, speed count, slower count, number stuff and stuff. 9 of the stuffs.

I printed a snug fitting collar for the end of the lathe spindle with a pocket for the magnet which was glued in place (be sure to check polarity first). A small box holds the board and display, a switch, and a 9V battery. The listing and photos have contradictory statements regarding voltage requirements, and the label stated 12-24V , but 8-24 seems to be correct. The device activates at a little over 8V. An aluminum bracket for holding the Hall sensor was attached to the back and that was it. The readings were accurate based in comparisons to a laser tachometer, and the display is fine and reasonably stable after a few seconds (the actual image is better than in the pictures because I just used a cell phone). Overall, this is a nice addition for 18 bucks. I subtracted one star because of the poor documentation. It is apparent from the reviews that many people found the hookup to be difficult. I believe it is actually very simple but needlessly confused by the bad description. One problem is that the connector wires are all white with red markings on the back to distinguish them. However, the photos show only the all white side. Since the plug can only be inserted one way, if the colored sensor wires connection to the labeled-side connector wires was shown in a single photo it probably would have eliminated all confusion. Anyway, several prior reviews have provided an accurate description of the hookup, and the Amazon description is also correct - just needlessly confusing. ## Frequently Bought Together - EEEkit 4 Digital Blue LED Tachometer, RPM Speed Meter Digital Motor with Hall Proximity Switch Sensor NPN for Conveyor Belts - uxcell a11121400ux0234 150K Ohm 2W Electrical Rotary Wirewound Pots Potentiometer with Knob - smseace 20Amp Electric Button Breaker 125/250VAC,Thermal Overload Protector L1 Series with Manual Reset, Waterproof Button Cap L1-20A --- ## 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.sn/products/120834747-4-digital-blue-led-tachometer-rpm-speed-meter-digital-motor](https://www.desertcart.sn/products/120834747-4-digital-blue-led-tachometer-rpm-speed-meter-digital-motor) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-06-02*
