Tube FurnacesPrecision Series System Features ^ Standard working tube of C610 ^ Separate or integrated control system ^ Master and slave controller availability ^ Customized controller option ^ High-quality fiber material ^ High level temperature uniformity ^ Multi zone design PZF series tube furnaces are multi-zone furnaces that could be used when laboratory experimentation is performed horizontally, vertically, or at specific angles. Configuration of the tilt angle, and the stable temperature working lengths make these furnaces suitable for many possible processes. With an easy to replace working tube as well as additional standard equipment options, these furnaces can be operated with multiple zones of different lengths. ^ System operation with solid-state-relays ^ Standard long working tube protruding from sides suitable for operation with flanges ^ Electrical protection ^ Galvanized coating covered epoxy paint structure ^ High quality heating elements ensuring a long service life ^ Intuitive controller user interface *For system accessories please check the accessory page for furnaces. Optional Features ^ Over-temperature limiter for thermal protection ^ Display of inner tube temperature with an additional thermocouple ^ Check valve at gas outlet ^ Gas supply and blend systems for operation ^ Alternative working tubes ^ Gas and water cooled vacuum flanges ^ Universal design for vertical and angular usage ^ Data logger with the software ^ RS422/485 communication
