Model ADP 21/31

 

 


Yamato model ADP-21 and ADP-31 Vacuum Drying Ovens greatly simplify the heating of samples at pressures below atmospheric. Significant features of the ADP-21/31 Vacuum Drying Ovens are as follows:

 

  • Precise control in a negative pressure environment. Microprocessor based three mode PID (Proportional Integral Derivative) with precise temperature control... 99% accuracy.
  • Microprocessor based safety circuit. Thermocouple malfunction is detected by microprocessor and heater is automatically shut off.
  • Economical. ADP-21/31 is the answer when cost is a primary concern.
  • Left or right opening door. Thanks to the unique door design which allows for either right or left opening, compensates for space limitation, and provides an extra measure of convenience.
  • Oven lined with Type 304 Stainless Steel for ease of cleaning.
  • Valves permit inert gas purge as well as vacuum operation.
  • The LED provides fast and positive display of operating parameters. Both SET and MEASURE are controlled and monitored digitally. Purging with Nitrogen or Argon is facilitated with gas inlet valve.
  • CSA approvable
