  • Automatic Pressure Control Switch (PIEZOSTAT)  State of art semi-automatic device controls the pressure inside the chamber mechanically and cuts-off the current from the heating elements when the desired/ set pressure value level is attained inside the chamber and restarts the mechanism once the pressure inside the chamber falls from the desired level.


  • Automatic Low Water Level Cut-off Device. (For protection of Heaters)  This device is a safety device for the protection of heaters. This device ensures that the heater automatically switches “off” in case the desired water level fall below the prescribed level & thereby protects it from burning.


  • Digital Temperature Indicator. This device indicates the temperature inside the chamber.


  • Digital Timer with Alarm System (optional). This is a semi-automatic device which is initiated once the pressure level inside the chamber reaches the desired value, it regulates the sterilization time of the media to be sterilized and when the desired time is passed, it activates the buzzer, which indicates that the sterilization cycle is complete and media can be extracted


  • Temperature Chart Recorder. This a semi automatic self contained easy to use recording device, which permanently records the temperature is any given sterilization cycle on a graph sheet.


  • Microprocessor based Digital Temperature controller Cum Indicator


  • PLC Control System



  • Above mentioned sizes are of standard Autoclave series. However, we are capable to manufacture/fabricate any special size as per customer’s exact requirement.


  • Following company’s constant endeavor to improve design & quality, the   instrument may differ in detail, description or as exhibited in this manual.
