SEM Vending Tester - Classic White

This is the original, field-proven SEM tester that preceded the CT3. This unit is refurbished with a 90-day warranty when operated by a trained vending technician. It tests the following interfaces and voltages: MDB, 12- and 15-pin logic changers (both 24VAC and 115VAC), and 115VAC single-phase changers. This versatile tester helps you save money on repairs and run more smoothly.  

These are popular, so the amount listed is all that is available.
