Product Introduction
　　ACT-2K Digital Temperature Controller is appended with alarm function on Digital Temperature Gauge ACT-201. It can display temperature data in field and send out alarm signals. It can be set with upper limit , lower limit and back-difference , then drive the relay output. Signal isolated design prevents it from interference. Its advantages of high control precision, fast reaction speed, stability , small volume, easy to install, makes it a substitute product for traditional electric contact instrument.
