Image note: The main photo shows the UT622C with a Chinese-language display example. Additional supplier photos show the related UT622E as a series illustration. This listing is for the UT622C and does not include DCR measurement.
The UNI-T UT622C measures inductance, capacitance, resistance and related component parameters at test frequencies up to 100 kHz. Included Kelvin test leads support four-wire measurement. The UT622E adds DCR measurement; this listing is for the UT622C.

The UT622C is a professional-grade handheld LCR meter that extends component testing to 100 kHz. Across 100 Hz, 120 Hz, 1 kHz, 10 kHz, and 100 kHz it measures L, C, R, impedance, ESR, and D/Q at 0.1% basic accuracy, with a 4-wire Kelvin connection and included Kelvin test leads for repeatable low-impedance readings.
The higher 100 kHz frequency characterizes parts closer to their working conditions — useful for production QC and design verification — with series/parallel modelling, open/short correction, and tolerance sorting on a portable Li-polymer-powered instrument.
Extending the top test frequency to 100 kHz lets you characterize capacitors and inductors closer to the frequencies they operate at, where parameters like ESR and impedance differ meaningfully from their low-frequency values — important for production QC and design verification.
A 4-wire Kelvin connection separates the drive and sense paths so lead and contact resistance don't corrupt the reading — essential for low-impedance components where milliohm-level errors matter. Open and short correction nulls fixture and lead effects before a measurement run.
Beyond L, C, and R, the meter reads impedance (Z), equivalent series resistance (ESR), dissipation factor (D), and quality factor (Q), with series or parallel equivalent-circuit modelling and impedance phase from −179.9° to 179.9° — the parameters needed to characterize a part, not just read its nominal value.
A tolerance-comparison function sorts parts pass/fail from 1% to 20% bands at up to 20 measurements per second, suited to incoming inspection and small-batch QC. Results log to 500 groups and transfer over USB.
A 2.8-inch color display, included Kelvin test leads, and a rechargeable Li-polymer pack good for about 8 hours make the UT622C ready for bench and line use.

Production QC and incoming inspection; design verification of capacitors and inductors at higher frequency; component characterization on the bench; and tolerance sorting in small-batch manufacturing.
It characterizes components closer to their operating frequency, where ESR and impedance can differ from low-frequency values.
Yes — Kelvin test leads are included for repeatable 4-wire low-impedance measurement.
The UT622E adds DC resistance (DCR) measurement from 0.01 mΩ to 20 MΩ on top of the same 100 kHz LCR capability.

Shipping availability depends on the product, supplier, and delivery address. Enter your address at checkout to see the available shipping options and final shipping charge before payment. If no shipping option is offered for your address, we cannot ship that combination of items to that destination. A shipping zone does not mean every product is available in every location.
Apex Technica works with fulfillment partners, including suppliers through Shopify Collective, who ship products directly to customers. An order containing products from different suppliers may ship in separate packages. Shipping charges may be combined across packages; review the total at checkout.
Order handling generally takes 3–5 business days before dispatch, but varies by supplier and product. Business days are Monday through Friday, excluding holidays. Carrier transit time is additional to handling time. Contact hello@apextechnica.com before ordering if you need an item-specific dispatch estimate or delivery by a particular date. For Collective products, available shipping rates and carrier transit estimates are calculated at checkout. Carrier transit estimates describe time in transit after dispatch, not a guaranteed order-to-delivery date. Weekends, holidays, carrier disruptions, and customs processing can affect delivery.
We send shipping confirmation and tracking details when they become available from the fulfillment partner. Separate shipments may have different tracking numbers and arrive on different days. Tracking can take time to show the carrier's first scan.
Check your address before placing an order. Contact Apex Technica promptly to request a correction or cancellation; changes may be unavailable once processing begins. If a shipment is delayed, missing, damaged, or incorrect, contact us with your order number so we can investigate with the supplier or carrier. Do not send an item back without return instructions. See our return and refund policy.

Apex Technica accepts return requests for products fulfilled by Apex Technica within 30 calendar days after delivery. This standard 30-day return window does not apply to products fulfilled by our Shopify Collective suppliers. Collective-fulfilled products are subject to the applicable supplier's return eligibility, return window, condition requirements, and fees, which may differ from our standard policy.
Review any supplier-specific return terms shown on the product page before purchasing. If those terms are not shown, contact hello@apextechnica.com before placing your order to confirm the applicable return window, eligibility, shipping costs, and any restocking fee. The exception does not mean that every Collective product is non-returnable. Apex Technica remains your contact for return requests and will coordinate with the supplier. Do not send products directly to a supplier without our return instructions.
For products covered by our standard 30-day policy, items must be unused, in their original packaging, and include all accessories and proof of purchase. This condition requirement does not prevent you from reporting a damaged, defective, or incorrect product.
Email hello@apextechnica.com with your order number, the item you want to return, and the reason for the request. Include photos if the item arrived damaged, defective, or incorrect. We will review the request and provide authorization, the correct return address, and shipping instructions. Returns are made by mail; items from different suppliers may require separate return shipments. Please retain tracking and proof of shipment.
For standard Apex returns due to a change of mind, the customer pays return shipping and original shipping charges are not refundable. We do not charge a restocking fee for eligible standard Apex returns. For damaged, defective, or incorrect items, contact us so we can arrange the appropriate return or other resolution without charging you return shipping. For Collective-fulfilled change-of-mind returns, supplier-specific shipping and restocking terms apply.
After the authorized return is received and inspected, we will notify you of the outcome. Approved refunds are issued to the original payment method within 10 business days after receipt and inspection. Your bank or payment provider may require additional time to post the credit. Any applicable, previously disclosed return charges will be explained. For exchanges, contact us to arrange a return and a separate new order; replacement availability is not guaranteed.
Contact Apex Technica promptly if your order arrives damaged or incorrect, has a defect, or does not arrive. We will investigate with the supplier or carrier and explain the available resolution. Manufacturer warranty coverage is separate from this return policy. Nothing in this policy or a supplier exception limits rights that cannot be excluded under applicable law.
