The F51 Crack Depth Detector is offered by China Coal Industry And Mining Group, located in Jining, Shandong, China. It measures surface crack depths up to 650 mm and records each test with a maximum error of ±10 mm. The unit stores up to 6,000 test data sets in its internal memory and displays results on a 160 × 128 pixel LCD screen. Power is supplied by six AA alkaline batteries, delivering more than ten hours of continuous operation.
The detector housing is fabricated from rugged engineered plastic, providing resistance to industrial environments. Its dimensions, 190 mm × 183 mm × 84 mm, fit comfortably on most inspection workstations. In the non‑destructive testing sector, devices of this class typically operate within a temperature range of - 10 °C to 50 °C and meet an accuracy standard of ±0.5 mm for repeatable measurements. Standard safety features include an over‑voltage protection circuit and a sealed keypad to prevent dust ingress.
The instrument is suited for steel manufacturers, pipeline inspectors and maintenance crews that need rapid on‑site crack assessment. Buyers usually request bulk shipments and may negotiate incoterms such as FOB or CIF, though exact quantities and pricing must be confirmed with the supplier. As the listing does not disclose a minimum order quantity, lead time or certification status, prospective importers should ask the supplier for those details before placing an order. The supplier’s response rate is currently recorded as zero, so clear written communication is advisable.

Before confirming a purchase, request the supplier’s calibration certificate and a copy of the device’s user manual to verify the 650 mm range and ±10 mm error claim. Ask for a recent factory inspection report that details the assembly process of the plastic housing and battery compartment. Confirm whether the detector complies with any regional safety standards such as CE or IEC 61010.
Discuss shipping options early; the supplier may offer FOB Jining or CIF Shanghai, but the exact incoterm must be agreed in the contract. Verify the package dimensions, which should accommodate the 190 mm × 183 mm × 84 mm unit plus protective padding. Ask for a pro‑forma invoice that includes freight estimates and the preferred payment method, typically T/T or L/C.
Arrange a third‑party inspection at the factory or upon arrival to check battery integrity, LCD functionality and IP54 enclosure rating. Request a functional test report that records sample measurements across the full 650 mm range. Ensure the supplier can provide a certificate of conformity for any applicable standards before the goods are released for shipment.
