VD02 Inductive Alarm Voltage Tester R

It is a non-contact voltage detector that beeps and lights up when it senses an electric field — so you can verify a wire is live without touching it.

Yes, the tester combines a loud audible alarm with a bright LED indicator, so it can be seen and heard even on a busy site.

Most models detect AC voltage from around 12V to 1000V. The exact range is listed in the product specifications.

Hold the tester near the wire or outlet — if it alarms, the circuit is live. Always test on a known-live source first to confirm the tester works, then test the target.

The same units work in both regions. All six models in the line, VD02, VD06, VD10, VD11, VD21 and VD123, are battery-powered non-contact detectors, so they never plug into the outlet and there is no plug or mains version to match. You differentiate between regions with the printed instructions language and packaging, not the hardware. For the AC detection range on each model, check the specifications table on the product page.

A common starting assortment is one compact entry model, VD02 or VD06, one middle option, VD10 or VD11, and one higher-featured unit, VD21 or VD123. That gives you three price points across the six-model line without carrying everything at once. For the exact differences in detection range, body size and buzzer output, check the specifications table on the product page, and we can send a mixed sample set so you can compare them before you order.

Yes. You can combine VD02, VD06, VD10, VD11, VD21 and VD123 in a single mixed-assortment order, and we carton each model separately so your warehouse can match each carton to your own SKUs. The minimum per model and carton quantity differ across the line, so tell our sales team the split you have in mind and we will confirm before you place the order. We are the factory in Wenzhou, so stock models ship on the regular lead time and production runs are scheduled on our own line.

Yes, all six models, VD02, VD06, VD10, VD11, VD21 and VD123, are available for private label. We can print your brand on the unit body and the box, and you can pick between color box and bulk carton packing for this line. Send us your logo and packaging design and we will confirm the printing method and any setup cost before production.

We serve both small trial orders and container-scale wholesale. Tell us the models and quantity you need, and our sales team will reply with pricing and lead time within 24 hours.

Yes. As a factory founded in 2008, we offer OEM/ODM services including custom labels, packaging and adjustable measuring ranges. Send us your specifications and we will handle the rest.

Every instrument ships with a 12-month warranty. If a unit is defective, contact us and we will arrange a replacement or repair.

Orders ship from our factory in Wenzhou, and we can arrange FOB Wenzhou or FOB Ningbo, whichever suits your freight forwarder best. For sea freight we pack into cartons and pallets sized for a 20ft or 40ft container, and for small or urgent orders we ship by air or express. In-stock catalog models ship within 3 to 7 days after payment, while OEM orders with custom branding take 15 to 30 days depending on the work.

For bulk orders we work on T/T bank transfer with a 30% deposit to confirm production and the 70% balance before shipment. For larger amounts we also accept L/C at sight. For sample orders we take PayPal or full T/T in advance, so your first test order stays simple.

Yes, we encourage a sample order before you commit to bulk, so you can check build quality and calibration yourself. Samples are sent by express and usually arrive within 3 to 7 working days, and we refund the sample cost from your first bulk order of the same model. Just send us the models you want through the contact form or email, and we will quote the sample and ship on payment.

We provide a commercial invoice, packing list and certificate of origin with every shipment, plus CE and RoHS certificates and test reports when needed. Our export team prepares the documents to match your country's customs requirements and can amend them if your forwarder requests changes. The documents are sent by email ahead of the goods, so clearance at your port is not delayed.
