MIZ-28 Eddy Current Test Instrument

The Zetec MIZ-28 delivers more technology and exceptional performance for high-speed and high-efficiency inspection of heat exchanger tubing. It comes equipped with industry leading data management features with more on-board data storage and easy file transfer. It also features two injection technologies in one box. Multiplexed and simultaneous injections are combined into one box that can test most tube materials, including magnetic alloys like carbon steel.

Velocity Software

We’ve taken our popular Eddynet PC software and customized it for the balance-of-plant (BOP)/heat exchanger (HX) market. Our easy-to-use Velocity Software is the most effective solution for data analysis and management.  It offers significant enhancements over our older ET Analysis and EIM BOP software.

Velocity AN for Analysis

  • Bobbin, MRPC and Array Analysis
  • Enhanced C-Scan
  • E-Resolution
  • Multi-datafile Comparison

Velocity DM for Data Management

  • Inspection Planning and Management
  • Historical Data Management
  • Test Plans
  • PID Test
