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
