Description
Product Introduction:
It is primarily used for photoresist curing, precision electronic components, and the drying of electronic ceramic materials.
Product Features:
1. Uses all-ceramic fiber insulation, ensuring rapid heating,
2. Supply and exhaust ventilation systems ensure uniform temperature within the furnace.
3. Fiberglass filter at the air intake, cleanliness requirements.
Oxygen content (oxygen analyzer):
1. Oxygen content in the high-temperature state: ≤10 ppm + oxygen content of the gas source;
2. Oxygen content in the low-temperature state: ≤20 ppm + oxygen content of the gas source
3. Temperature control stability: +1°C; temperature uniformity: +10°C
Control Output:
1. Temperature control instruments: Standard configuration includes a Fuji temperature controller from Japan; an Isokon temperature controller from Japan is available as an option.
2. Control: Independent temperature control, gas supply, and alarm protection for the furnace chamber;
3. Number of temperature control segments: 4 × 10 segments; Number of temperature control points: 2 points;
4. Number of over-temperature alarm points: 2; Number of detection points: 2;
5. Alarm and Protection: Audible and visual alarms for overtemperature, thermocouple failure, etc.; Overtemperature Protection: Independent temperature‑sensing overtemperature protector; Motor Protection: Motor overcurrent protection and water‑cooling protection; Surface Temperature Rise: <30°C;
