The price of an electromagnetic ultrasonic thickness probe varies widely because it is not a single commodity. A basic electromagnetic ultrasonic (EMAT) thickness probe for common carbon steel can cost $300 to $900. A high-temperature or high-resolution model often ranges from $1,200 to $3,500. Custom probes for boilers, pipelines, or automated inspection systems can exceed $5,000.

Several factors affect cost. Frequency, crystal size, cable length, connector type, temperature rating, and wear resistance all change the final quote. EMAT probes also require a compatible pulser-receiver and thickness gauge, which adds to the total investment. A complete portable kit with probe, cable, couplant-free setup, calibration blocks, and software may cost $2,000 to $8,000.

Cheap probes may suit simple thickness checks on clean metal. For corrosion monitoring, high-temperature steam lines, or rough surfaces, a premium probe is usually more reliable. Always confirm compatibility with your instrument, measurement range, and material type. Ask suppliers for a demo or calibration certificate. In short, expect $300 to $5,000 for the probe alone, or $2,000 to $8,000 for a full working system.

Prices also depend on brand, warranty, and supplier support. Imported EMAT probes often cost more than generic models. If you need custom coil design, fast repair, or frequent calibration, expect $1,500 to $4,000. Used or rental probes may cost less, but always verify accuracy. Ask for a detailed quotation. Confirm warranty terms.
