HW312 Voltage Tester R

A digital voltage tester shows an actual voltage reading on a display, instead of only indicating "live or not". This helps you confirm the voltage level, not just that power is present.

Yes. Most of our digital voltage testers include outlet testing with a clear digital readout, so you can verify wiring quickly.

Many models are auto-ranging — they select the right range automatically and show the reading. Check the model's specifications to confirm.

Yes, they combine speed with a precise readout, which makes them a practical choice for everyday electrical service work.

For a hardware or electrical supply counter, the 88 series (88-2, 88-4, 88-5, 88-6, 88-12) and the HW31x handheld line (HW311, HW312, HW313) are solid retail choices. For a wider stock list that serves both retail and wholesale customers, add 130805, 130855, MVD765 and WILK301 alongside them. We are the factory in Wenzhou, so send us your target channel and we will recommend the exact SKU mix for your first order.

HW311, HW312 and HW313 are three handheld digital voltage testers in the same CHINYOO family, and the models differ in measurement range and feature set. Open the specifications table on each product page and compare the AC/DC range and any extra functions before you order. If the differences are not obvious to you, order a small first lot of two models and scale up the one that sells in your market.

Yes, mixed-assortment containers are normal for this line, and you can combine models such as 130805, 130855, 1881, BQMVT646, HW311, HW312, HW313, 6877-18 and 6877-58 in a single order. Most digital voltage tester SKUs are stock lines with short production lead time, and the exact timing depends on quantity and whether the units are bulk or custom-labeled. Send your SKU list and we will confirm the per-model MOQ and delivery date before you place the order.

Yes, under an OEM agreement we can print your brand on the housing and packaging for the digital voltage tester line, including models such as 6877-18, 6877-58, 6885-48, SG5003A and SG8001. Packaging can be branded color boxes, blister packs, or bulk cartons depending on your channel. Per-model custom branding minimums apply, so send the SKU list and artwork, and we will confirm the order requirements.

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.

Our instruments are CE, RoHS and ISO 9001 compliant, and we can provide the relevant certificates on request.

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.
