Features
 |
|
|
3 GROUP ZONE PID ALGORITHM Complete temperature range is divided into three zones (LOW/MIDDLE/HIGH) and each ZONE has its individual PID Algorithm to provides precise and superior temperature control characteristic of whole temperature range. |
|
|
3 POINT CALIBRATION FUNCTION An excellent calibration tool to calibrate chamber at THREE DIFFERENT TEMPEATURE POINTS to adjust multiple TEMPERTURE BIAS to increase temperature accuracy of whole temperature range. |
|
|
1 POINT OFFSET CALIBRATION Provides simple and easy calibration tool to calibrate chamber at ONE SPECIFIC TEMPERTURE POINT of frequent use. |
|
Performance |
|
• Control Temperature Range from ambient+10 oC to 250 oC • Natural (Gravity) air convection for drying applications of fine powder and/or glassware • Asymmetrically designed heating system enhances mild and uniform hot air circulation for better temperature uniformity • 50mm thick high thermal efficiency mineral wool with woven aluminum barrier sheet saves energy and less dust
