1.Which type of vacuum pump can I choose for the electric drying oven?

The laboratory drying oven produced by our company can be equipped with a rotary vane vacuum pump, a diaphragm pump and a circulating water vacuum pump. Please contact us for specific specifications.

2. Can I monitor the temperature inside the instrument in real time?

Of course, you can observe the real-time temperature through the LED display for your convenience.

3.Why can't the laboratory blast drying oven be vacuumed?

-The vacuum pump is not the correct model specification.
- Various connecting pipes (heads) are loose, and the inner diameter is too fine
- Vacuum gauge damage
-The drying box door is not closed
- Vacuum drying oven door seal rubber aging loses elasticity
-The bleed valve and vacuum valve are connected incorrectly

4.Laboratory blast drying oven temperature measurement error alarm solution.

If “---” is displayed on the display window, it indicates that the temperature sensor is faulty or the temperature exceeds the measurement range or the controller itself is faulty. The controller automatically turns off the heating output, the buzzer sounds continuous, and the alarm light is always on. Please check the temperature carefully. Sensor and its wiring.
