Forced convection ovens with controlled temperature upto 250°C through Microprocessor LED Digital Temperature Controller with Auto Timer & Alarms.


  • Designed for critical laboratory applications for controlled temperature range up to 250°C with an accuracy of ± 0.5°C.
  • Integrated built-in see-thru toughened glass window in the double-walled door.
  • Forced convection model accounts for temperature uniformity and higher control accuracy.
  • Auto cut-off of blower and heaters on door open position.
  • Seamless rounded back edges of internal work chamber and semicircular arcs at corners ensures easy clean-up and uniformities.
  • Temperature Range : Upto 25˚C
  • Temperature Accuracy : ± 0.5˚C
  • Microprocessor Based Autotune PID temperature controller for PV/SV indication, timer, and cycle end alarm.
  • These units are featured with Microprocessor Based AUTOMATIC DIGITAL TEMPERATURE INDICATOR-CUM-CONTROLLER with an in-built DIGITAL TIMER to control the temperature. Once the unit is switched “ON” heating starts automatically and once the set/desired value is achieved the in-built AUTOMATIC DIGITAL MINUTE TIMER starts automatically. Once this set time period is over the heaters are switched “OFF” automatically and the unit sounds a BUZZER, thus alerting the user that process is complete.
  • Inner chamber and adjustable trays are made of Stainless Steel (SS-304 grade).
  • Outer body made of CRC Sheet duly powder coated.
  • Horizontal on face cross-flow air circulation accounts for tighter uniformities and accuracy.
  • Specially designed silicone door gaskets accounts for minimal heat dissipation and leakages thus accounts in electrical energy servings.
  • To work on 220/230V AV, 50/60 Hz supply.
