DT83 Series

It measures AC/DC voltage, AC/DC current and resistance — the essentials for home repairs, electronics work and basic electrical troubleshooting.

Yes. For socket checks, appliance repairs and DIY projects, a basic multimeter covers the vast majority of jobs while staying affordable and easy to read.

Accuracy varies by model — typically 0.5% to 1% for DC voltage. The exact spec is listed in each model's datasheet and specifications table.

Yes, we are the factory. Distributors and wholesalers are welcome — send your target models and quantity for wholesale pricing and lead time.

For a first order, stock the DT830 or A830L as the entry price point and the DT838 or DM101 as the step-up tier. That gives you two price bands without tying up container space in slow SKUs, and you can add DT832, DT858L or XT802 later based on sell-through. If you are not sure which band sells in your market, order both in roughly equal quantities and reorder from the data. Compare the full functions on each model's specifications table before you fix the mix.

Most distributors run two tiers for this line: the DT830, DT830L and A830L for hardware and home channels, and the DT838, DT850L or DT858L for trade and auto customers who pay up for the step-up model. You can keep a single SKU to simplify stock, but splitting the order lets you match price bands to each channel. Tell us your expected split by customer type and we will quote per-model pricing for the full order.

Yes, we are the factory in Wenzhou, so we can print your brand on the meter face, the dial and the box for the basic DMM line, including DT830, DT832, DT838, DM101 and the rest of the range. For retail we offer printed color boxes with a fitted insert; for cost-sensitive programs we ship bulk packs with a plain carton and your label applied. Send us the models and packaging you want and we will confirm print minimums and artwork lead time for each model.

Return the defective meters with your order number and we will repair or replace them at our Wenzhou factory, and we check the same production lot so you can keep the remaining stock on the shelf with confidence. For wholesale orders we process claims by lot and can credit the replacement value against your next order to save on return freight. The process covers the whole basic DMM line, from the DT830L to the XT803.

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.
