Variacs

J-KEM's variac is built with solid state electronics making it the perfect instrument for research, especially useful in teaching labs.

Safety features include sparkless solid state regulation of voltage for oil baths, heating mantles, heat lamps, and many other devices. Offered in two configurations, the Trinity-1 replaces an existing receptacle for installation directly in hoods or other outlets. The Trinity-2 comes in its own case with an attached power cord. Both the Trinity-1 and Trinity-2 are offered with and without a built-in analog voltage meter.
