Muffle Furnace – 1400°C

Muffle Furnace – 1400°C

Digiqual 1400°C Muffle Furnace Construction comprises of double walled chamber, outer made of cold rolled mild steel sheets and finished in powder coating paint. inner chamber formed by High temperature withstand zirconia vacuum board followed by ceramic fibre blankets on all the sides. double walled door mounted on heavy-duty hinges in the front is provided with effective locking arrangements. optionally, the door can be provided with door limit switch to cut off the power supply whenever the door is opened and to restart when the door is closed.

The High Temperature Furnace 1400°C / Muffle Furnace will be heated by means of HIGH QUALITY SILICON CARBIDE RODS. Temperature is maintained and controlled by Digital PID temperature controller with SSR output. Alternatively a Microprocessor based PID Controller auto tuned with Thyristor control Device working in conjunction with Pt/Pt/Rh 13% Thermocouple.
