Digital Trainer



Accessory Backpack  
                              The ETW-3567 Backpack coupled with any 3000 or 5000 series trainer form a teaching combination unparalleled in versatility, expandability and convenience - and tough enough to withstand the rigors of classroom use.

The Backpack allows the use of pre-wired experiment boards so that your students won't use valuable lab time breadboarding - they'll spend their time learning.

The Backpack features three power supplies and a built-in digital voltmeter. The voltmeter enables your students to do many of their experiments on a trainer without additional test instruments.

Experimentation with live circuits is an essential ingredient in an electronics training program. These Heathkit Electronics Trainers enable the student to get the hands-on, real-circuit experience that they will need to master the many aspects of electronics.

These trainers are built to withstand years of classroom use. Connector blocks are recessed for extra durability. The power supplies are protected against short circuits and overloads. The breadboard are removable, so more than one student can work with a single trainer at the same time.
