ST201 Digital Clamp Meter

A clamp meter measures AC/DC current without breaking the circuit — you just clamp around a single conductor. It is the standard tool for motor, panel and machine current checks.

Yes, our digital clamp meters are multimeters too — they measure voltage, resistance, continuity and diode tests in addition to clamp current.

Most of our models measure up to 400A or 600A AC/DC. The exact range is listed in each model's specifications table.

If you mainly measure current on live wires or motor circuits, choose a clamp meter. For general voltage and resistance testing, a multimeter is more compact. We offer both.

For a general electrical trade market, the 266 family is the natural core of an assortment: the 266, XT266, XT266C and XT266FT share the 266 form factor and measure up to 1000A AC current. The VC3268 series (VC3268, VC3269, VC3270) is a separate catalog tier, and models like MT87, MT2010A and ST201 cover lighter and budget needs. We are the factory in Wenzhou, so share your customer segment and we will recommend an opening mix with the price tiers.

All three are part of the same 266 family, share the 266 form factor and measure up to 1000A AC current, so the difference is in added functions and the accessories in the box. The exact differences between XT266, XT266C and XT266FT are listed in the specifications table on each product page, and we can email a side-by-side comparison with your quotation. For a first order, start with the base XT266 and add the C and FT variants once your customers show which feature set they want.

Yes, you can combine models like XT266, VC3270, MT2010A and DM6266F in a single container order, and we will quote each model separately. The per-model minimum depends on the packaging and accessory kit, so send us your target SKU mix and we will confirm the minimum for each. High-volume models are usually available from stock, while less common ones such as XT266FT or ST201 may be made to order, so confirm lead time when you place the order.

Our clamp meters carry a 12-month warranty from the date of delivery. If units arrive defective or fail in use, send photos or a short video and we will confirm the fault; for a defective batch we arrange replacement or a credit against your next order. Because CHINYOO's factory is in Wenzhou, we can trace the production batch and keep spares for the 266 family and the VC3268 series, so claims are settled against the actual build, not through a middleman.

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.
