商品簡介

甲醛氣體感測器檢測模組輸出TTL電壓信號（可接單晶片微電腦IO連接埠如51等）和電壓模擬信號，另外模組可以檢測醛類/苯類/芳香類/酮類等。檢測誤差和一致性屬於中低端檔次。應用於定性判斷和非肯定性定量檢測。受VOC和TVOC氣體干擾，交叉數據較明顯。

 

商品特色

  • 具有信號輸出指示燈
  • 雙路信號輸出（模擬量輸出及TTL電壓輸出）
  • TTL輸出有效信號為低電壓；（輸出低電壓時信號燈亮，可接單晶片微電腦IO連接埠）
  • 模擬量輸出隨濃度增加而增加，濃度越高電壓越高
  • 對醛、醇、酮、芳族化合物具有很高的靈敏度
  • 可長期使用和可靠的穩定性
  • 快速反應並恢復特性
  • 帶安裝孔，方便固定安裝
  • 探頭可以插拔設計，方便試驗
