Arrow Springs ASC/4 Temperature Controller

Selling my Arrow Springs ASC/4 temperature controller. It's a solid unit for glass work or kilns, helps keep things steady. It has the DTT-23 digital display from Canadian Instrumentation. Everything looks to be in decent shape, just don't need it anymore. Has the toggle switch for power and the relay cut out switch on the front. Pretty straightforward to use if you know your way around a kiln setup.
