Three-Wire connection enable the Voltage Test Rang from 0.00 to 30V. (Two-wire meters cannot measure the voltage that is below 3V); - Measurement Accuracy: 0.01(0.01 - 9.99V) / 0.1(10.0 - 30.0V); And the meter is CALIBRATABLE: The screw on the back is used to Calibrate the meter. - BRIGHT & NICE Reading: Display: Three 0.36" digital LED Tube; Display Color: Red; - Reverse Polarity Protection: The meter won't burn out if reverse polarity is applied, but the screen will display nothing - NOTE: When measured voltage is larger than 30V, the voltmeter will be damaged. ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B00YALUXH0 | | Best Sellers Rank | #62,451 in Automotive (See Top 100 in Automotive) #28 in Automotive Voltmeter Gauges | | Brand Name | bayite | | Color | red | | Customer Reviews | 4.6 4.6 out of 5 stars (663) 4.6 out of 5 stars | | Item Dimensions | 0.9 x 0.55 x 0.39 inches | | Item Weight | 4.54 g | | Lower Temperature Rating | 14 °F | | Manufacturer | bayite | | Measurement Type | Voltmeter | | Minimum Operating Voltage | 3 volts_of_direct_current | | Model | 3B001x5 | | Part Number | 3B001x5 | | Style Name | Digital | | Unit Count | 5 Count | | Upc | 711463670098 | | Upper Temperature Rating | 149 °F | ## Product Details - **Brand:** bayite - **Color:** red - **Item Weight:** 0.01 Pounds - **Item dimensions L x W x H:** 0.9 x 0.55 x 0.39 inches - **Style:** Digital ## Images ![Pack of 5 DC 0-30V Digital Volt Meter, 3-Wire Voltage Gauge, Red LED | Measures Below 3V | Calibratable | Reverse Polarity Protection - Image 1](https://m.media-amazon.com/images/I/61iMNnewyhL.jpg) ![Pack of 5 DC 0-30V Digital Volt Meter, 3-Wire Voltage Gauge, Red LED | Measures Below 3V | Calibratable | Reverse Polarity Protection - Image 2](https://m.media-amazon.com/images/I/71+5PiNQOVL.jpg) ![Pack of 5 DC 0-30V Digital Volt Meter, 3-Wire Voltage Gauge, Red LED | Measures Below 3V | Calibratable | Reverse Polarity Protection - Image 3](https://m.media-amazon.com/images/I/710z-uqI8DL.jpg) ![Pack of 5 DC 0-30V Digital Volt Meter, 3-Wire Voltage Gauge, Red LED | Measures Below 3V | Calibratable | Reverse Polarity Protection - Image 4](https://m.media-amazon.com/images/I/61m8VNqDonL.jpg) ![Pack of 5 DC 0-30V Digital Volt Meter, 3-Wire Voltage Gauge, Red LED | Measures Below 3V | Calibratable | Reverse Polarity Protection - Image 5](https://m.media-amazon.com/images/I/61943qv846L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy to read, 5 pack, inexpensive, works great *by on Reviewed in the United States May 18, 2026* Excellent 5 pack of digital meters that are large enought to easily read. Used for solar readings on batteries in kitchen so I dont have to go the battery and controller/inverter area to check the condition of the system. ### ⭐⭐⭐⭐⭐ Easy to use and accurate little voltmeter. *by on Reviewed in the United States May 19, 2020* Great little voltmeter! Mounting is easy, I 3D printed a shroud to help with this and added some smoky Lexan to cut the brightness down a bit and improve the contrast. Calibration is simple and accurate, I set the 10ths digit to roll over to the next value with the input voltage reaches 0.05V (i.e. an input voltage of 12.44 reads as 12.4 on the LED, and 12.45 reads as 12.5). The accuracy is very good over the input range and the 10ths digit does not jump around excessively. Overall this is a very easy to use and acceptable voltmeter for most projects. I used it here in a mobile amateur radio setup to measure power supply/battery voltage and boosted voltage.I do wish the 3 wires were accessible so you could join the white and red (voltage for the LCD driver and voltage to measure) but they solder to the surface of the PCB under the LED, not a big deal though. ### ⭐⭐⭐⭐⭐ Great size, excellent function. *by on Reviewed in the United States February 8, 2026* Great size, excellent function. ## Frequently Bought Together - bayite Pack of 5 Three-Wire Calibratable DC 0~30V Red Digital Mini Voltmeter Gauge Tester Mount Car Motorcycle Battery Monitor Volt Voltage Meter 0.36" Red LED Display Panel - bayite Pack of 5 Three-Wire Calibratable DC 0~30V Blue Digital Mini Voltmeter Gauge Tester Mount Car Motorcycle Battery Monitor Volt Voltage Meter 0.36" Blue LED Display Panel --- ## 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.pt/products/28274208-pack-of-5-dc-0-30v-digital-volt-meter-3](https://www.desertcart.pt/products/28274208-pack-of-5-dc-0-30v-digital-volt-meter-3) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-08-02*
