A voltage tester quickly checks whether a circuit or outlet is live. It is the first tool an electrician picks up before touching any wiring.

A voltage tester gives a fast "live or not" answer and is cheaper and simpler to use. A multimeter measures exact voltage, current and resistance values. Many electricians carry both.

Yes, our basic voltage testers cover both AC and DC ranges suitable for household and light industrial work. Check the specifications table on each product page for the exact range.

Yes. They are CE and RoHS compliant and built with insulated housings. Always verify the tester works on a known-live source before and after use, and follow local electrical safety rules.

We are CHINYOO, the factory in Wenzhou, and we can help you put together a starter assortment for your channel. The 1AC-D and AC-1 are our compact non-contact detectors for pocket carry, and the 1805A/B/C/D family gives you four detection-level variants under one SKU series. The M100 and M200 round out the value end of the line if your customers want a lower-priced basic tester. Check the specifications table on the product page to match each model's rated voltage range to your local 120V or 230V supply.

Yes. The 1805A/B/C/D is one SKU series with four rated-voltage variants, so you can order a mix that matches the voltages your customers work with and manage it as a single part number. If you prefer a simpler pocket pen instead, the 1AC-D and AC-1 are the two single models. Check the specifications table on the product page for the detection range of each variant, and our sales team will confirm the per-variant minimum and lead time before you order.

Yes, we accept mixed-assortment container orders, so you can combine the 1AC-D, AC-1, the 1805A/B/C/D family and the EW001/EW002/EW003 testers in one shipment as long as each model meets its per-model minimum quantity. The 1AC-D and AC-1 are our steady stock models and leave Wenzhou faster than production-built units. For the per-model MOQ and lead time on slower SKUs such as the 1808, 1809 or 1888, confirm with our sales team before you finalize.

Yes, OEM printing is standard across this line. We print your logo and model marking on the 1AC-D, AC-1, 1805A/B/C/D and the EW series housings, and on the blister card or retail box. If you distribute to resellers rather than selling shelf-ready, we can ship the 1AC-D and AC-1 in bulk packaging without retail boxes. Send us your artwork and we will quote the packaging option, with CE and RoHS marking included on the label.

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.

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.
