Frequently Asked Questions
Is this part compatible with my device?
This listing is for UNI-T UT139A UT139B UT139C True RMS Digital Multimeter Ohmmeter Capacitance Tester Ammeter Auto Range AC DC Voltmeter. It is built as a direct-fit replacement for the model named in the title. Match the model number in the title against your own device before ordering. If you are not sure which version you need, email sales@iProGadget.com and we will confirm the correct part for you.
What is the quality of these replacement parts?
We supply iProGadgets OEM Quality / Premium Compatible replacement parts. Every part is manufactured to OEM specifications, so the fit, finish and function match the original component it replaces, and each unit is individually tested before it leaves our warehouse.
Is the part tested before it is shipped?
Yes. Every part we sell is inspected before dispatch and tested wherever testing applies — screen assemblies are checked on the panel, the touch response and the connector. Orders are processed and shipped within 1-3 business days after payment is confirmed.
How long does shipping take?
Orders leave our warehouse within 1-3 business days. Express Shipping (DHL, UPS or FedEx) takes 5-8 working days and is normally used for parcels over 2 kg. Registered Air Post takes 10-20 working days and is normally used for parcels under 2 kg. Every order ships with a tracking number. Customs clearance can add extra time, especially during peak season.
Will I be charged import duties or customs fees?
Customs charges depend on your own country's import rules and its de minimis threshold, not on the seller. Some destinations apply no duty at all on lower-value parcels, and where duty or VAT does apply it is collected by your local post office or courier before delivery. We ship every order with complete and accurate commercial documents, which is what keeps a parcel moving through customs instead of sitting in it. If you would like to estimate the charges before you order, email us your country and we will point you to the right authority.
What is your return policy?
We offer a 30-day return policy, which means you can request a return within 30 days of receiving your item. To be eligible, the item must be unused, uninstalled and in the packaging it arrived in. Once a part has been fitted, bonded or used it cannot be returned, so please test the part before installation. To start a return, email sales@iProGadget.com.
What should I do if the part arrives damaged or faulty?
Inspect your order as soon as it arrives. If an item is defective, damaged or not what you ordered, contact us at sales@iProGadget.com straight away with photos or a short unboxing video, and we will arrange a replacement or a refund.
Do you provide repair guides or installation tutorials?
No. We are a supplier of replacement parts only. We are not a repair shop, and we do not provide repair guides, tutorials or step-by-step installation support. Every part we sell is intended to be installed by a professional technician at a qualified repair shop, which also gives the best result: a technician can transfer the small components, handle the adhesives and test the finished repair. Please do not attempt the installation yourself if you have no previous repair experience, as these assemblies are fragile and incorrect handling can damage them permanently. We sell parts only and do not accept responsibility for installation carried out by the customer. Our warranty covers the part itself and remains valid until the part is installed. If a problem appears after the repair, please take the device back to the repair shop that fitted the part so they can inspect the installation and test the device.
Still have a question about this part? Email us at sales@iProGadget.com and we will confirm compatibility, shipping time or return details for you.
