The handheld calibrators HZ‑3521 and TKSX‑3 are 3‑phase energy meter calibration devices offered by Wuhan GDMK Electric Co., Ltd. They are marketed as high‑precision test instruments for field verification of power meters and are built for portable use on site. Both models incorporate built‑in voltage and current measurement functions and support automatic range switching across four voltage gears.
The voltage measuring range spans 0 to 400 V with automatic stepping at 57.7 V, 100 V, 220 V and 400 V. Current measurement covers 0 to 5 A via an internal transformer and optional clamp heads that reach up to 2000 A (5 A, 25 A, 100 A, 500 A, 400 A, 2000 A). Phase‑angle detection is continuous from 0 to 359.999°, while frequency is recorded between 45 and 55 Hz, matching typical utility grid conditions.
Typical buyers include electric utilities, metering laboratories and field service contractors who need on‑site verification of meter accuracy. The equipment is supplied without publicly disclosed minimum order quantities or price points, so interested parties should request a formal quotation. Buyers are advised to confirm any calibration certificates, warranty terms and the specific incoterm that will apply to the shipment.

Checking the supplier’s quality‑system documents, such as ISO or CE compliance, is also advisable.
Logistics for this product are typically arranged under FOB or CIF terms, but the exact incoterm must be agreed with Wuhan GDMK Electric Co., Ltd. Lead‑time estimates are not disclosed in the listing, so ask the supplier for a production and shipment schedule. Payment methods commonly include T/T in advance or after inspection, but confirm the preferred method and any escrow options before finalising the contract.
