The ultimate engineers tool for calibration / validation of welding machines to BS EN50504

This range of Calibrator machines have set new standards for validation / calibration equipment and have become the leading product for validation in Europe.

The Calibrator 500i AC DC is extremely portable, weighs only 12.5kg and doesn’t need any external power supply. This design really speeds up the whole process of setting up and validating all types of machines including, MIG, MAG, MMA, TIG. They can also be connected to TIG machines with the HF running.

The Calibrator 500i is based around a resistive load bank (dummy load) with very accurate digital meters built in, the unique cooling design allows for a very compact and light machine unequalled by any competitive product.

Features and Functions:

• Hand portable – weighs only 12.5kg.
