MS-4A四聯加熱磁力攪拌器 4 Heads Magnetic Stirrer

MS-4A四聯加熱磁力攪拌器采用特制搪瓷盤加熱技術，表面最高溫度可達到340℃。磁力攪拌子攪拌技術，人性化操作設計，可滿足多種加熱攪拌實驗需求。

4 Heads Magnetic Stirrer has single-point and multi-point simultaneous stirring function, with mechanical timing, easy operation and stepless speed regulation, which can stably and precisely stir the liquid in a wide range. It is a common tool in petroleum, chemical industry, medical and health, environmental protection, biochemical laboratories, analysis rooms, and education departments.

1. 四個加熱盤面獨立控溫控速，獨立顯示。

2. 外殼采用金屬外殼，高強度，耐高溫，防腐蝕。

3. 控溫采用PID控制算法，數字顯示，精度高，沖溫小（±5℃以內），內、外PT1000測溫。

4. 可對50ml~2L×4標準或非標準反應瓶進行加熱或攪拌。

5. 直流無刷電機，性能穩定，噪音小，壽命長，無火花產生。
