The Digital Thickness Measuring Instrument for Steel, model RUM7401, is an ultrasonic meter designed to assess wall thickness and corrosion on pressure vessels, chemical equipment, boilers and oil storage tanks. It offers a measuring range of 0.75 mm to 400 mm on 45 # steel, a large LCD screen, aluminium‑alloy housing and a resolution selectable at 0.01 mm, 0.1 mm or 0.001 in, with an accuracy of ±(0.5 % n + 0.05). The device stores material codes and sound‑velocity values automatically and provides USB, RS‑232 and optional Bluetooth output for data logging.
The instrument’s aluminium‑alloy case protects the internal high‑performance micro‑processor while the large LCD ensures clear reading in industrial environments. Bidirectional measurement lets users either input known thickness to obtain material velocity or input known velocity to calculate thickness, a feature common to modern ultrasonic meters. Typical ultrasonic thickness meters for steel use a 2 MHz probe, operate on less than 5 W power and are calibrated every six months to maintain accuracy, aligning with standard industry practice.
Target users include maintenance teams in petroleum refineries, shipyards, power stations and machine‑manufacturing plants that require reliable corrosion monitoring. Qingdao Realltech offers the meter with optional Bluetooth data transfer, packaged in sturdy boxes suitable for sea freight, and allows buyers to discuss MOQ, lead‑time and Incoterms directly with the supplier. Prospective importers should confirm the exact probe type, calibration certificate and shipping details before placing an order.

Before placing an order, buyers should request the latest calibration certificate for the RUM7401, verify that the aluminium‑alloy housing matches the specification listed, and confirm the exact probe model that will be supplied. It is also advisable to ask for a sample data file to ensure the USB or Bluetooth output meets your data‑integration requirements. These checks reduce the risk of receiving equipment that does not align with your inspection standards.
Logistics for this supplier are typically arranged from the Qingdao port. Packaging is performed in reinforced wooden crates to protect the LCD screen and electronics during sea transport. Importers should agree on Incoterms such as FOB or CIF, clarify the expected lead‑time, and confirm payment terms - commonly a 30 % deposit by T/T with the balance payable upon shipment. All of these details must be finalised in the purchase contract.
Quality assurance is best supported by a third‑party inspection before loading. Inspectors should verify the ultrasonic calibration against a known reference block, confirm the accuracy specification of ±(0.5 % n + 0.05), and review the stored material‑code database. Request copies of any ISO or CE certificates the supplier claims, and ensure that the test reports cover the full measuring range of 0.75 mm to 400 mm.
