This auto measuring pen is designed for mechanics and DIY users who need quick, accurate detection of voltage on car systems, ceiling lights, and other 5V to 30V circuits. With a clear dual-colour display and a flexible spring wire that reaches 1.2 metres, it eliminates the need to juggle separate tools while working under the bonnet or around the dashboard. The TPU antifreeze material body keeps it functional even in colder workshops, making it a practical addition to any tool kit.\u003c\/p\u003e\u003ch2\u003eFeatures and Construction\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Auto measuring pen with TPU body and spring wire for 12V 24V circuit testing\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US12\/5929\/2025-10-24\/original-image\/2b962005-af3a-4a9a-9c55-44c48532f99d.webp\"\u003e\u003c\/div\u003e\u003cp\u003eBuilt for durability and ease of use, this measuring pen combines a compact form with a robust spring wire and straightforward controls. Its design focuses on giving clear voltage feedback without complicated settings.\u003c\/p\u003e\u003ch3\u003eMaterial and Build\u003c\/h3\u003e\u003cp\u003eThe body is made from TPU antifreeze material, which remains flexible and impact-resistant at low temperatures. This construction means the tool can be used reliably during winter months or in unheated garages without becoming brittle. The pen measures just 138 x 17mm, so it fits comfortably in a pocket or toolbox drawer.\u003c\/p\u003e\u003ch3\u003eSize and Practical Fit\u003c\/h3\u003e\u003cp\u003eIts slender profile and lightweight design allow one-handed operation while probing connectors or terminals. The spring wire, which stretches to 1.2 metres, provides enough reach to connect to a chassis ground or battery negative without straining the tool or the user. The fine probe tip option helps access tight spaces on modern engine bays.\u003c\/p\u003e\u003ch2\u003eUses and Placement\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Auto measuring pen with TPU body and spring wire for 12V 24V circuit testing\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US12\/5929\/2025-10-24\/original-image\/3a1850a4-84cb-4e60-9f1a-4df1cac749ed.webp\"\u003e\u003c\/div\u003e\u003cp\u003eThis tester is suited for a range of automotive and low-voltage electrical tasks, from checking fuses and relays to verifying power at light sockets or sensors.\u003c\/p\u003e\u003ch3\u003eEvent or Professional Use\u003c\/h3\u003e\u003cp\u003eAuto repair shops and mobile mechanics benefit from the pen's ability to quickly identify live circuits with a voltage range of 5V to 30V. The ceiling lamp detection works for interior lights and indicator panels, distinguishing 2V to 30V signals with red or green LED indicators.\u003c\/p\u003e\u003ch3\u003eEveryday Home Use\u003c\/h3\u003e\u003cp\u003eDIY enthusiasts can use it for basic car diagnostics, such as testing trailer lights, battery voltage, or fuse continuity. The simple light display means no training is needed to understand the result.\u003c\/p\u003e\u003ch2\u003eBenefits and Buying Value\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Auto measuring pen with TPU body and spring wire for 12V 24V circuit testing\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US12\/5929\/2025-10-24\/original-image\/49914ce1-dac2-4bcb-ab1a-ff9dd959303f.webp\"\u003e\u003c\/div\u003e\u003cp\u003eInstead of carrying a multimeter for every simple check, this dedicated test light offers a faster, more focused solution for voltage presence and polarity.\u003c\/p\u003e\u003ch3\u003eReuse and Low Maintenance\u003c\/h3\u003e\u003cp\u003eThe TPU body resists cracking and the spring wire is permanently attached, so there are no loose parts to lose. No batteries are required for basic voltage detection, reducing long-term running costs.\u003c\/p\u003e\u003ch3\u003eWhy Choose This Product\u003c\/h3\u003e\u003cp\u003eAvailable with or without an LED tip and fine probe, you can select the configuration that matches your typical work. The 1.2-metre wire gives plenty of slack, and the wide voltage coverage works on both 12V and 24V systems used in cars, trucks, and motorcycles.\u003c\/p\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Auto measuring pen with TPU body and spring wire for 12V 24V circuit testing\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US12\/5929\/2025-10-24\/original-image\/8e6a4ce9-8280-402d-9c25-07fc5854d7b6.webp\"\u003e\u003c\/div\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Auto measuring pen with TPU body and spring wire for 12V 24V circuit testing\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US12\/5929\/2025-10-24\/original-image\/8f6e0b0f-543e-4b04-b0f2-9c24d7427151.webp\"\u003e\u003c\/div\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Auto measuring pen with TPU body and spring wire for 12V 24V circuit testing\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US12\/5929\/2025-10-24\/original-image\/cdfd21dc-60b6-43d7-bffd-5ec8e1308a6e.webp\"\u003e\u003c\/div\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Auto measuring pen with TPU body and spring wire for 12V 24V circuit testing\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US12\/5929\/2025-10-24\/original-image\/da37e4b5-c0c7-4c06-81fa-a8d9d204e403.webp\"\u003e\u003c\/div\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Auto measuring pen with TPU body and spring wire for 12V 24V circuit testing\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US12\/5929\/2025-10-24\/original-image\/db246327-18bd-400e-8955-32de0d33bcc1.webp\"\u003e\u003c\/div\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Auto measuring pen with TPU body and spring wire for 12V 24V circuit testing\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US12\/5929\/2025-10-24\/original-image\/f2842ea0-a4d1-411e-a3c1-483bd0f709e5.webp\"\u003e\u003c\/div\u003e","brand":"umvdr2-sp","offers":[{"title":"Black","offer_id":58316045582600,"sku":"CJQT165338505EV","price":28.68,"currency_code":"GBP","in_stock":true},{"title":"Black with Fine probe","offer_id":58316045615368,"sku":"CJQT165338506FU","price":29.68,"currency_code":"GBP","in_stock":true},{"title":"Black LED with Fine probe","offer_id":58316045648136,"sku":"CJQT165338508HS","price":32.68,"currency_code":"GBP","in_stock":true},{"title":"Black LED","offer_id":58316045680904,"sku":"CJQT165338507GT","price":31.68,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1039\/4664\/9864\/files\/8f6e0b0f-543e-4b04-b0f2-9c24d7427151.webp?v=1785214966","url":"https:\/\/avermora.com\/products\/auto-measuring-pen-12v-24v-multifunctional-auto-repair-test-light-circuit-maintenance-detection-tool-with-tpu-antifreeze-body-spring-wire-1-2m-5v-30v-detection-voltage-range-black-led-fine-probe-options","provider":"Avermora.com","version":"1.0","type":"link"}
